Psychological risk factors in headache

A comprehensive analysis of patients with cerebral arteriovenous malformation with headache: assessment of risk factors and treatment effectiveness

BACKGROUND

Due to the high mortality and disability rate of intracranial hemorrhage, headache is not the main focus of research on cerebral arteriovenous malformation (AVM), so research on headaches in AVM is still scarce, and the clinical understanding is shallow. This study aims to delineate the risk factors associated with headaches in AVM and to compare the effectiveness of various intervention treatments versus conservative treatment in alleviating headache symptoms.

METHODS

This study conducted a retrospective analysis of AVMs who were treated in our institution from August 2011 to December 2021. Multivariable logistic regression analysis was employed to assess the risk factors for headaches in AVMs with unruptured, non-epileptic. Additionally, the effectiveness of different intervention treatments compared to conservative management in alleviating headaches was evaluated through propensity score matching (PSM).

RESULTS

A total of 946 patients were included in the analysis of risk factors for headaches. Multivariate logistic regression analysis identified that female (OR 1.532, 95% CI 1.173-2.001, p = 0.002), supply artery dilatation (OR 1.423, 95% CI 1.082-1.872, p = 0.012), and occipital lobe (OR 1.785, 95% CI 1.307-2.439, p < 0.001) as independent risk factors for the occurrence of headaches. There were 443 AVMs with headache symptoms. After propensity score matching, the microsurgery group (OR 7.27, 95% CI 2.82-18.7 p < 0.001), stereotactic radiosurgery group(OR 9.46, 95% CI 2.26-39.6, p = 0.002), and multimodality treatment group (OR 8.34 95% CI 2.87-24.3, p < 0.001) demonstrate significant headache relief compared to the conservative group. However, there was no significant difference between the embolization group (OR 2.24 95% CI 0.88-5.69, p = 0.091) and the conservative group.

CONCLUSIONS

This study identified potential risk factors for headaches in AVMs and found that microsurgery, stereotactic radiosurgery, and multimodal therapy had significant benefits in headache relief compared to conservative treatment. These findings provide important guidance for clinicians when developing treatment options that can help improve overall treatment outcomes and quality of life for patients.

Pain medication beliefs in individuals with headache

OBJECTIVE

To evaluate pain medication beliefs in a community sample of individuals with headache.

BACKGROUND

Previous studies of medication adherence for individuals with headache have identified a high rate of prescription nonfulfillment, frequent medication discontinuation, and widely varying levels of medication-related satisfaction. Still, there is a limited understanding of how these individuals view their medications and their relationships with health-care providers. Insight into these perceptions could prove useful in explaining medication adherence behaviors.

METHODS

In this secondary analysis of a cross-sectional study, data from N = 215 adults with headache were analyzed. Participants completed the Pain Medication Attitudes Questionnaire (PMAQ), Center for Epidemiologic Studies Depression Scale (CES-D), State-Trait Anxiety Inventory Form Y-2, Weekly Stress Inventory Short Form, and Migraine Disability Scale. These participants also provided a list of their current pain medications.

RESULTS

Using the PMAQ, participants could be characterized as having medication beliefs that were "trusting and unconcerned" (n = 83/215 [38.6%]), "skeptical and somewhat worried" (n = 99/215 [46.0%]), or "skeptical and concerned" (n = 33/215 [15.3%]). Individuals with skeptical and concerned beliefs expressed elevated concerns (z > 1.15) about side effects, scrutiny, perceived need, tolerance, withdrawal, and addiction. Individuals who were trusting and unconcerned expressed low levels (z < -0.40) of these beliefs. Increasing levels of mistrust and medication concerns were correlated with higher depression scores on the CES-D, with values ranging from r = 0.23 to r = 0.38.

CONCLUSIONS

Subgroups of pain medication beliefs were identified, including two groups of patients with at least some concerns about their medical providers. Beliefs ranged from a lack of concern about using pain medications to worries about scrutiny and harm. It is unclear if poor experiences with pain medications cause these beliefs or if they prevent individuals from effectively utilizing medications. Additionally, more negative beliefs about pain medications were associated with more depressive symptoms.

Effectiveness of intensive short-term dynamic psychotherapy for Tension-Type Headache (TTH): A randomized controlled trial of effects on emotion regulation, anger, anxiety, and TTH symptom severity

Research has demonstrated the potential efficacy of intensive short-term dynamic psychotherapy (ISTDP) in addressing medically unexplained symptoms (MUS). However, the specific application of ISTDP for tension-type headache (TTH), a prevalent and common MUS, has not been extensively studied. In light of this gap in the literature, the current study investigated the effectiveness of intensive short-term dynamic psychotherapy (ISTDP) in treating TTH. The study assessed ISTDP's impact on emotion regulation (ER) capacities, levels of anxiety and anger, and TTH symptoms. 30 patients from the neurology clinic at Hazrat Rasool Hospital in Tehran were randomly assigned to either the intervention (n = 15) or control (n = 15) group. Pre- and post-treatment evaluations were conducted, followed by a ten-week follow-up assessment. Data were analyzed using repeated measures analyses of variance. The results indicated that ISTDP led to significant improvements in ER, reductions in anxiety and anger levels, and a significant decrease in TTH symptoms (ps < 0.001). Findings underscore the effectiveness of ISTDP as a valuable therapeutic approach for addressing TTH.

Headache Prevalence and Its Associated Factors in Makkah, Saudi Arabia

Primary headaches are more prevalent and associated with several risk factors, such as chronic diseases, unhealthy lifestyles, smoking, caffeine intake, work, and stress. However, these factors are not associated with specific headache disorders. We investigated the prevalence of primary headache disorders and the associated risk factors in Makkah. This cross-sectional study, conducted over a 6-month period, used an anonymous survey disseminated through online platforms. The questionnaire was a modified version of a validated questionnaire used to assess headaches in relation to modifiable and non-modifiable risk factors. In total, 1177 participants aged 18-65 (mean, 31.5 ± 12.6) years were included. Headaches were diagnosed among 44.2% of participants aged 20-59 years, with a high prevalence among young adults; additionally, 71.5% of participants with headaches reported experiencing headaches for <15 days per month. Chronic headaches were found in 28.5% of participants. Age, chronic diseases, work, caffeine consumption, and smoking were associated with having a significant effect on headache prevalence. The prevalence of headaches in Makkah has increased in comparison to that reported in previous studies. Certain modifiable and non-modifiable risk factors have been associated with headaches. Headaches impact all life aspects of individuals and communities. An educational program for professionals and patients can improve patient outcomes.

Understanding the gaps in headache and migraine treatment with psychological and behavioral interventions: A narrative review

OBJECTIVE

In this narrative review, we summarize relevant literature pertaining to psychosocial risk factors for headache and migraine progression, current behavioral and psychological treatments, and consider promising treatments.

BACKGROUND

Headache and migraine are common and associated with significant burden and disability. Current treatments targeting psychosocial risk factors show modest outcomes and do not directly address the impact of early life adversity, including the development of maladaptive emotional processing. An intervention that could address these factors and include components of current evidence-based interventions may lead to improved outcomes.

METHODS

We searched PubMed and Google Scholar for articles through December 2022. Search terms included headache, migraine, psychological interventions, behavioral interventions, cognitive-behavioral therapy, mindfulness, psychiatric comorbidities, adverse childhood experiences, trauma, and emotional processing.

RESULTS

Trauma and childhood adversity show a correlation with headache and migraine progression. Developmental adversity and trauma interfere with adaptive emotional processing, which may worsen headache and migraine symptoms, while adaptive ways of experiencing emotions are shown to improve symptoms. Current behavioral and psychological interventions, such as cognitive-behavioral and mindfulness therapies, are effective treatments for headache, but they produce small to medium effect sizes and do not directly address the impact of trauma and emotional conflicts-common factors that contribute to chronicity and disability, especially among certain subpopulations of headache patients such as those with migraine. Thus, there exists a gap in current treatment.

CONCLUSION

There is a gap in headache and migraine treatment for those patients who have a history of trauma, childhood adversity, and maladaptive emotional processing. We suggest that an integrated psychological treatment that includes components of current evidence-based interventions and addresses gaps by focusing on processing trauma-related emotions may improve chronic and debilitating symptoms.

Associations of Sociodemographic and Psychosocial Factors with Headache Symptom Among Indonesian Adolescents Based on the 5th Wave of the Indonesian Family Life Survey (IFLS-5)

BACKGROUND

Headaches are common among children and adolescents, with more than half of adolescents reporting headache symptom worldwide. The number of migraine sufferers among adolescents has increased dramatically in the past decade. Headache has negatively influenced children and has been linked with emotional and behavioral problems.

STUDY DESIGN

A cross-sectional study.

METHODS

This study was conducted using secondary data from the Indonesian Family Life Survey (IFLS) to evaluate the relationship between sociodemographic and psychosocial factors in Indonesian adolescents and headaches. We used data from the fifth wave of IFLS, which was conducted between September 2014 and April 2015. The figures represent roughly 83% of the Indonesian population. We investigated the possible relationship between sociodemographic and psychosocial factors in adolescents with headaches.

RESULTS

A total of 3605 participants (1875 females and 1730 males) aged 15 to 19 years with headache symptom were included in the study. Headache was associated with sleep disturbances (OR 1.99; 95% CI: 1.72, 2.30), depression (OR 1.94; 95% CI: 1.65, 2.28), and female gender (OR 1.72; 95% CI: 1.50, 1.98). Other factors contributing to headaches include poor/moderate sleep quality (OR 1.25; 95% CI: 1.08, 1.45) and low income (OR 1.22; 95% CI: 1.01, 1.48).

CONCLUSION

In Indonesian adolescents aged 15 to 19 with headaches, sleep disturbances were the dominant factor associated with headache occurrence. Other factors such as depression, female gender, low socioeconomic status (SES), and poor/moderate sleep quality showed a positive association with headaches but further large population-based studies with more refined variables are needed to elucidate this association.

Headache-a challenge across medical students' life: a systematic review and meta-analysis

BACKGROUND

Headache is a disabling disease that affects psychosocial factors. Medical students are recognized to be more susceptible to psychological stress than other. Quantitative summaries of prevalence studies on this subject are limited. The aim of this study was to quantify and comprehend the variance in prevalence at the global and regional levels.

METHODS

We used a comprehensive search approach to find studies on headaches prevalence in the medical literature published between November 1990 and May 5, 2022. Database searched were PubMed, Scopus, EMBASE, and Google Scholar. Studies that reported headaches (unspecified, migraine, or tension-type headache (TTH)) in medical students were included. Subgroup analysis and meta-regression were applied to investigate heterogeneity, with the risk of bias tool employed to assess study quality. PROSPERO number CRD42022321556 was assigned to the study protocol.

RESULTS

Out of 1561 studies, 79 were included. The pooled prevalence estimates of unspecified headache, migraine, and TTH were 70.44% (95% CI: 63.32-77.57), 18.9% (95% CI: 15.7-22.0), and 39.53% (95% CI: 31.17-47.90), respectively. TTH and migraine were more prevalent in Eastern Mediterranean and American region. TTH and migraine were less prevalent in higher income countries.

CONCLUSION

Although the prevalence of headaches among medical students varies in different countries, it is higher than the general population of the same age. Higher stressors and overwork in these students may contribute to this condition. The well-being of medical students should be a priority for the relevant authorities.

Pain-Related Cognitive Processes, Pain Interference, and Alexithymia in Patients With Primary Headaches

Objectives This study aims to investigate the effects of pain-related cognitive processes (PRCPs) and emotional state on pain-related disability (PRD) and pain interference (difficulty in performing daily routines, difficulty in engaging in social activities [the enjoyment of life], and the impact on work and/or school performance) in patients with primary headaches (PHs). Methodology PRCPs were evaluated with the Pain Anxiety Symptom Scale-20 (PASS-20), Pain Catastrophizing Scale (PCS), and Pain Belief Questionnaire (PBQ). Anxiety, depression, and alexithymia were investigated to assess the emotional state. PRD was assessed by Headache Impact Test-6 (HIT-6). Health-related quality of life (HRQoL) was evaluated under three headings: daily activities (with Short Form-36 [SF-36] Question [Q] 22), social activities (with Graded Chronic Pain Scale-Revised [GCPS-R] Q 4), as well as the working ability (with GCPS-R Q 5). Two separate models were constructed to identify the factors influencing PRD and HRQoL in PHP: M1 to reveal the factors affecting PRD and M2 to determine the independent factors affecting pain interference. In both models, correlation analysis was applied first and the significant data were then evaluated with regression analysis. Results A total of 364 participants (74 healthy controls [HCs] and 290 PHPs) completed the study. In M1, the following domains were significantly associated with PRD: cognitive anxiety (β = 0.098; 95% confidence interval [CI] = 0.001-0.405; P = 0.049); helplessness (β = 0.107; 95% CI = 0.018-0.356; P = 0.031); alexithymia (β = 0.077; 95% CI = 0.005-0.116; P = 0.033); depression (β = 0.083; 95% CI = 0.014-0.011; P = 0.025). In M2, factors associated with impairment in daily activities for PHP were as follows: duration of pain, pain intensity, alexithymia, escape-avoidance response, psychological anxiety, anxiety, and poor sleep quality (R = 0.770; R² = 0.588). The independent factors affecting social activities for PHP were pain intensity and pain-related anxiety (R = 0.90; R² = 0.81). Independent risk factors that affected the ability to work for PHP were pain intensity, cognitive anxiety, escape-avoidance response, and pain anxiety (R = 0.90; R² = 0.81). Conclusions This study highlights the importance of cognitive and emotional processes that help increase our understanding of the patient with PHs. This understanding may help to reduce disability and improve the quality of life in this population by helping to guide multidisciplinary treatment goals.

Psychosocial factors associated with pain outcomes in patients with painful temporomandibular disorders and headaches

The objective of this study was to assess the association between psychosocial factors (in terms of anxiety, somatization, depression, and optimism) and pain (in terms of headache pain intensity and pain-related disability), in patients with a painful temporomandibular disorder (TMD) and one of the following headache types: migraine, tension-type headache (TTH), or headache attributed to TMD, corrected for the influence of bruxism. A retrospective study was conducted at an orofacial pain and dysfunction (OPD) clinic. Inclusion criteria were painful TMD, with migraine, TTH, and/or headache attributed to TMD. Linear regressions were performed to assess the influence of psychosocial variables on pain intensity and on pain-related disability, stratified per headache type. The regression models were corrected for bruxism and the presence of multiple headache types. A total of 323 patients (61% female; mean age 42.9, SD 14.4 years) were included. Headache pain intensity only had significant associations in TMD-pain patients with headache attributed to TMD, and anxiety showed the strongest relation (β = 0.353) with pain intensity. Pain-related disability was most strongly associated with depression in TMD-pain patients with TTH (β = 0.444), and with somatization in patients with headache attributed to TMD (β = 0.399). In conclusion, the influence of psychosocial factors on headache pain intensity and pain-related disability depends on the headache type presenting.

Stress-induced headache in the general working population is moderated by the NRCAM rs2300043 genotype

OBJECTIVES

Earlier findings suggest that social stress such as abusive supervision may promote pain. In the present study we examine the possible moderating role of genetic variability in the NRCAM gene in this process.

METHODS

The data were collected through a national survey drawn from the National Central Employee Register by Statistics Norway. A total of 1,205 individuals returned both the questionnaire and the saliva kit. Abusive supervision was scored by a 5-item version of the Tepper's 2,000 scale. Headache was measured on a four-category scale; 'not bothered,' 'a little bothered,' 'considerably bothered', 'seriously bothered'. Genotyping with regards to NRCAM rs2300043 was carried out using Taqman assay. Ordinal logistic regression was used to analyse the data.

RESULTS

For males exposed to abusive supervision, those carrying the rs2300043 CC genotype reported the highest levels of headache. Women showed a trend towards the opposite pattern. Women with the rs2300043 CC genotype seem to have a weaker effect of abusive supervision regarding reported headache than their male counterparts with the CC genotype when exposed to abusive supervision.

CONCLUSIONS

The present results indicated that the association between abusive supervision and headache in men with the NRCAM rs2300043 C allele was stronger than in other men. This suggests that the NRCAM genotype in men is important for the tolerance of social stress e.g., repeated negative acts from a superior. In contrast, a trend, though non-significant, towards the opposite pattern was observed in women. Our result suggests that the NRCAM genotype in men manifestly affects stress-induced pain such as headache.

Psychological Responses of Health Care Workers Are Strongly Associated With Pandemic Management

Background

Globally, governments adopted protective measures to stabilize the worsening COVID-19 pandemic situation. These measures had a large impact on health care workers (HCWs) and could make the work environment more stressful for them. Therefore, we explored the associations of the psychological responses of HCWs and pandemic management among Slovak health care workers during the second wave of the pandemic.

Materials and Methods

We obtained data about psychological responses, COVID-19 experiences, information overload, non-adherence of the public, work stress and barriers and facilitators of health care provision from HCWs at the COVID-19-related departments of one hospital that mainly covered eastern Slovakia (215 health care professionals, 77.7% females, M/SD = 44.4). Data were analyzed using logistic regression models adjusted for gender.

Results

Pandemic management was most strongly associated with psychological responses, such as irritability, sadness, anxiety, dizziness, and back pain, in health care workers. The non-adherence of the public had the strongest associated psychological impact on HCWs, mostly affecting anxiety and irritability (odds ratios, ORs varying from 3.9 to 7.0). From the barriers and facilitators of health care provision, the use of personal protective equipment had the most impact psychologically, whereas efficient department management was most protective, with ORs around 0.3.

Conclusion

Pandemic management has a large impact on health care workers, and promoting resilience may seriously decrease job-related stress and associated psychological responses of HCWs.

An evaluation of the correlation between the severity and frequency of migraine and the Buss-Perry Aggression Scale

It is important to identify concomitant psychological factors such as depression and aggression in patients with migraine. In this study, our objective was to demonstrate the difference of aggression scores in patients with migraine compared with normal scores, and whether the severity of the disease and the frequency of pain had an impact. Ninety-nine patients with migraine and 67 healthy controls who presented to the Okmeydanı Training and Research Hospital were included in the study. The pain frequency, duration, and severity of the migraine were recorded. The respective severities of pain, depression and aggression were evaluated using a visual analogue scale (VAS), the Beck Depression Scale, and the Turkish version of the Buss-Perry Aggression Questionnaire. It was found that the anger scores of patients with migraine were high (p = 0.001; p < 0.01), and their hostility levels were lower compared with those of the control group in a case (p = 0.017; p < 0.05) where there was no difference in depression level (p > 0.05). No difference with the control group was found in terms of physical and verbal aggression. It was found that internalised anger was significantly higher. No correlation was found with the frequency and duration of pain. The anger scores of patients with migraine are higher, which may be directly related to the nature of migraine without any contribution of depression. The long-term impacts of the disease, and an evaluation of the psychological concomitants within the scope of the treatment plan are important for a more effective treatment method.

Role of Yoga as an Adjunct in the Management of Migraine Headache-Current Status and Future Indications

Migraine headache is a painful, disabling condition afflicting 7% of the population. The long-term effort of coping with a chronic headache disorder predisposes the individual to other psychiatric illnesses, ischemic cerebrovascular disease as well as medicine overuse headache. The use of nonpharmacological methods to reduce the stress and pain associated with headache can improve the overall quality of life and reduce the burden of the disease. To examine the utility of yoga as an adjunct to pharmacological treatment of migraine headache. The review article is based on the secondary literature collected through the Google Scholar database between the years 2010 and 2020. Several themes were identified regarding the burden of migraine/headache and the need for the integration of yoga into the existing healthcare system. Despite the limitations and the need for greater scientific rigor, there have been consistent reports of the beneficial effects of yoga in the reduction of stress, anxiety, depression, and an enhanced quality of life, as well as better pain management in chronic diseases. Studies on the role of yoga in the treatment of migraine have been few in number. They have consistently shown that yoga can be a valuable adjunct to the existing pharmacological interventions in the management of migraine headache. In recent years, the Indian government has made enormous strides in establishing yoga outreach programs throughout the country. The need of the hour is to integrate evidence-based yoga with the wellness centers and noncommunicable diseases treatment plan. It can help to reduce the burden on the existing health care resources.

The profile of musculoskeletal pain and its associations with sleep quality and depression during the COVID-19 in Turkey

Background

The current pandemic has affected people’s health multidimensionally. This study aims to investigate musculoskeletal pain, sleep quality, depression levels, and their relationships in individuals belonging to different age groups during COVID-19 in Turkey.

Methods

A web-based self-administered survey that consisted of demographic questions, The Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), and scores of musculoskeletal pain was sent to participants. Pearson correlation analysis was used for determining the statistical relationship between variables.

Results

The study includes 1,778 participants. The highest percentage for mild, moderate, and severe pain was in the head (49.8%), back (15.5%), and head (11.5%), respectively. The PSQI-total had shown a weak correlation with pain levels in all body parts. The highest correlation for sleep quality and pain levels was between the PSQI-5 and lower back pain. There was a weak correlation between PSQI-2 and the BDI score, and a moderate correlation between the PSQI-1, PSQI-5, PSQI-7, PSQI-total, and BDI score. Pain in all body parts showed a weak correlation with depression level.

Conclusions

This study showed that musculoskeletal pain was varied in body parts with different intensities according to age groups in Turkey during the pandemic. The most common pain was in the head, back, and lower back. Headache was found correlated with the parameters of sleep quality. Pain of the head, neck, back, lower back, and shoulder were correlated with sleep latency. Sleep quality was associated with depression and musculoskeletal pain, while musculoskeletal pain was correlated with depression.

Brazilian version of headache management self-efficacy scale

Background Headache-management self-efficacy has been associated with pain severity and headache-related disability. Objective The aim of this study was to test the cross-cultural adaptation and psychometric properties of a Brazilian version of the Headache Management Self-Efficacy Scale (HMSE) in a sample of patients coming from three tertiary headache centers in Brazil. Methods 137 migraine outpatients completed the Headache Management Self-Efficacy Scale (HMSE) and measures of psychopathological symptoms, pain catastrophizing, depression, anxiety, quality of life and headache-related disability. Results HMSE-10 showed good reliability (α = 0.84) and adequate corrected item-total correlation, ranging from 0.46 to 0.64. HMSE-10 was positively correlated with 6 of 8 domains of overall health status and negatively correlated with psychopathological symptoms, depression, anxiety, pain catastrophizing, headache-related disability, headache frequency and headache intensity. The difference between the means of the episodic and chronic headache patients had a magnitude of moderate effect in all the study measures, being headache-related disability the largest one found (d = 0.68). Along with headache intensity and depression, Efficacy Scale beliefs were predictors of headache-related disability. Conclusions The Brazilian short version of Headache Management Self-Efficacy Scale (HMSE-10) was revealed as a valid and reliable measure of headache-specific Efficacy Scale beliefs.

A Bio-Psychosocial Framework for Chronic Daily Headaches: A Mixed Methods Study

Chronic daily headaches (CDH) are primarily understood from a psychophysiological formulation. A broad biopsychosocial understanding, where there is equal importance given to biological, psychological and socio-cultural factors, is underexplored in headache. Socio-cultural factors, such as gender, socio-economic factors can perpetuate and worsen the condition. For an effective and sustainable intervention, these factors need to be considered. The current study aims to explore and develop a biopsychosocial framework for headache disorders. A convergent parallel mixed methods design was used and participants were recruited from a tertiary referral care hospital, Bengaluru, India. Headache Assessment Sheet, GAD 7, HDRS, PSS and B COPE were used in the quantitative phase. The data was analysed using r software. Qualitative phase of the study, in depth interview guide was used and data analysed thematically. Quantitative phase, 38 participants were recruited. The average age, was 38.02 (±10.17), majority of the participants being females 31 (81.58%). The mean duration of illness was 8.63 (±4.73) years. The anxiety scores positively correlated with pain intensity (r = 0.50 at P ≤ .001) and the median anxiety scores varied with photophobia (P ≤ .03). The anxiety scores correlated with PSS (r = 0.428 at P ≤ .007) and HDRS (r = 0.428 at P ≤ .007) scores. Gender variations in coping were seen, avoidant coping having higher median scores in women. (P ≤ .08). In qualitative phase of the study, six participants were recruited. Three main themes emerged from the qualitative phase of the study: headache - an illness, headache factors and the impact. Chronic daily headaches are influenced by biological, psychological, environmental and socio-cultural factors. A bio-psychosocial framework will help to understand and develop targeted interventions.

The impact of Pain-related emotions on migraine

The response to pain is highly individual and can be influenced by complex emotional perception. This study aims to investigate the status of the pain-related emotional response, and the influence on headache characteristics and disability in migraine. We studied the pain-related emotional response in 145 consecutive migraine patients using the Pain Anxiety Symptoms Scale (PASS), the Pain Catastrophizing Scale (PCS), and the Pain Sensitivity Questionnaire (PSQ) and compared them with 106 healthy controls. We investigated the relationship between emotional factors and migraine characteristics. The effect of pain-related emotion on migraine-related disability assessed with the Headache Impact Test-6 (HIT-6) and the Migraine Disability Assessment (MIDAS). Migraine patients showed significantly higher scores on total PASS (p < 0.001), PCS (p < 0.001) and PSQ (p = 0.002) compared to the healthy controls. The HIT-6 was weakly correlated with PASS (r = 0.390, p < 0.001) and PCS (r = 0.354, p < 0.001). PASS-Total (p = 0.001), headache frequency (p = 0.003), and HADS-Anxiety (p = 0.028) were independent variables associated with HIT-6. Headache frequency (p < 0.001) was an independent variable associated with MIDAS. The structural equation model indicated that headache severity has direct loading on emotion and subsequently influenced migraine-related disability. Disability has a significant effect on the frequency of abortive medication use. Migraine patients have altered emotional responses to pain perception. Pain-related anxiety made an important contribution to headache-related disability. The present results suggest that the management of disability by considering various pain-related emotional factors may be necessary for the therapeutic aspects of migraine.

Exploring Emotional Distress, Psychological Traits and Attitudes in Patients with Chronic Migraine Undergoing OnabotulinumtoxinA Prophylaxis versus Withdrawal Treatment

This explorative cross-sectional study aims at exploring emotional distress, psychological profiles, and the attitude towards receiving psychological support in eighty-seven patients with chronic migraine (CM) undergoing OnabotulinumtoxinA prophylactic treatment (OBT-A, n = 40) or withdrawal treatment (WT, n = 47). The outcomes were explored through a specific battery of questionnaires. 25% of patients undergoing OBT-A and almost half of the patients undergoing WT reported psychological distress of at least moderate-severe level, respectively. Coping strategies, self-efficacy, and perceived social support were similar in the two groups. Patients undergoing OBT-A presented lower psychological inflexibility than patients undergoing WT. Predictors of higher psychological distress were low perceived social support by friends, low self-efficacy, and higher avoidance strategies. In both groups, most of the patients evaluated receiving psychological support to be useful (79%). The potential beneficial effects of OBT-A on the severity of symptoms and psychological distress might further support its role in the multidisciplinary management of patients with CM. Identifying patients with psychological vulnerabilities who may benefit from psychological support is relevant in patients with CM.

Perceptions, experiences, and understandings of cluster headache among GPs and neurologists: a qualitative study

BACKGROUND

Cluster headache is a severe primary headache with a similar prevalence to that of multiple sclerosis. Cluster headache is characterised by unilateral trigeminal distribution of pain, ipsilateral cranial autonomic features, and a tendency to circadian and circannual periodicity.

AIM

To explore the perceptions, experiences, and understandings of cluster headache among GPs and neurologists.

DESIGN AND SETTING

Qualitative interview study in primary care surgeries and neurology departments in the north of England.

METHOD

Semi-structured interviews were conducted with GPs and neurologists, recorded, and transcribed. A thematic analysis was applied to the dataset.

RESULTS

Sixteen clinicians participated in this study: eight GPs and eight neurologists. Four main themes were identified following thematic analysis: challenges with the cluster headache diagnosis; impact of cluster headache; challenges with treatment; and appropriateness of referrals to secondary care. Clinicians recognised the delays in the diagnosis of cluster headache, misdiagnosis, and mismanagement, and were aware of the potential impact cluster headache can have on patients' mental health and ability to remain in employment. Findings highlighted tensions between primary and secondary care around the cost of medication and the remit of prescribing treatment regimens. Patients' anxiety, their need for reassurance, and their insistence about seeing a specialist are some of the reasons for referrals.

CONCLUSION

Clinicians acknowledged delays in diagnosis, misdiagnosis, and mismanagement of cluster headache. The responsibility of prescribing causes ongoing tensions between primary and secondary care. Clear referral and management pathways for primary headaches are required to improve patient outcomes and healthcare costs.

Temporomandibular disorders, pain in the neck and shoulder area, and headache among musicians

Background

Uncertainties still exist about the role of playing musical instruments on the report of musculoskeletal complaints and headache.

Objectives

To evaluate the prevalence of and risk indicators for symptoms of temporomandibular disorders, pain in the neck or shoulder, and headache among musicians.

Methods

A questionnaire was distributed among 50 Dutch music ensembles.

Results

The questionnaire was completed by 1470 musicians (response rate 77.0%). Of these, 371 musicians were categorised as woodwind players, 300 as brass players, 276 as upper strings players, 306 as vocalists and 208 as controls; nine musicians had not noted their main instrument. The mean age was 41.6 years (standard deviation [SD] 17.2), and 46.5% were male. Irrespective of instrumentalist group, 18.3% of the musicians reported TMD pain, 52.5% reported pain in the neck and shoulder area, and 42.5% reported headache. Of the functional complaints, 18.3% of the musicians reported TMJ sounds, whereas a jaw lock or catch on opening or on closing was reported by 7.1% and 2.4%, respectively. TMD pain was associated with playing a woodwind instrument, whereas pain in the neck and shoulder was associated with playing the violin or viola. For each complaint, oral behaviours were found as risk indicator, supplemented by specific risk indicators for the various complaints.

Conclusions

The current finding that pain‐related symptoms varied widely between instrumentalist groups seems to reflect the impact of different instrument playing techniques. Playing a musical instrument appears not the primary aetiologic factor in precipitating a functional temporomandibular joint problem.

State and trait anger and its expression in cluster headache compared with migraine: a cross-sectional study

BACKGROUND

Anger is involved in the emotional experience of pain. Individuals with migraine are more likely to hold their anger-in than controls. However, only one study evaluated anger in cluster headache (CH). The objective is to compare anger between migraine and CH patients.

METHODS

One hundred thirty-five migraine and 108 CH patients completed the State Trait Anger Expression Inventory (STAXI-2), composed of 7 subscales. State Anger measures the intensity of the individual's angry feelings at the time of testing. Trait Anger evaluates general predisposition to become angry. Anger Expression Out and Anger Expression In measure the extent to which anger could be overtly expressed or suppressed. Anger Control Out and Anger Control In evaluate how individual try to control the outward or inward expression of anger. Anger Expression Index is a general index.

RESULTS

CH patients have higher median scores than migraine patients in State Anger (46 vs 44, p = 0.012). CH patients have lower scores in Anger Control Out (44 vs 50, p = 0.016). In subgroup analysis, CH patients during the cluster period have higher scores than chronic migraine patients in State Anger (47 vs 44, p = 0.035), while CH patients in headache-free period did not differ from migraine patients.

CONCLUSIONS

Migraine and CH patients differ in state anger, indicating that CH patients experienced higher intensity of anger during the time of testing. These data add new information about emotional regulation in headache patients and could support the hypothesis of different emotional and behavioral responses to pain in migraine and CH patients.

The role of psychosocial risk factors in the burden of headache

Purpose: Psychosocial risk factors are common in headache patients and affect the impact of headache in multiple ways. The aim of our study was to assess how psychosocial risk factors correlate with the headache impact test-6 (HIT-6). To our knowledge this is the first study to evaluate the impact of several psychosocial factors on the HIT-6 score.

Patients and methods: Our study population consisted of 469 Finnish female employees reporting headache during the past year. Psychosocial risk factors were assessed using validated, self-administered questionnaires: the generalized anxiety disorder 7-item scale (GAD-7) for anxiety, the major depression inventory (MDI) for depressive symptoms, the ENRICHD short social support instrument (ESSI) for social isolation, the cynical distrust scale for hostility and the Bergen burnout indicator (BBI-15) for work stress.

Results: Exploratory factor analysis of the HIT-6 scores revealed two factors, one describing psychological and quality of life aspects affected by headache and the other describing severity of pain and functional decline. Internal consistency of the HIT-6 was 0.87 (95%CI: 0.85–0.89). Correlations between the total HIT-6 score and all measured psychosocial risk factors except for hostility were weak, but statistically significant.

Conclusion: The HIT-6 questionnaire has good construct validity and it describes reliably and independently the impact of headache without interference of psychosocial factors in general working-aged female population.

Cross-Sectional Evaluation of the Psychometric Properties of the Headache-Specific Locus of Control Scale in People With Migraine

OBJECTIVE

This study aims to investigate the psychometric properties (component structure, reliability, and construct validity) of the Headache-Specific Locus of Control scale in several clinical migraine populations.

BACKGROUND

Headache-specific locus of control beliefs may impact a person's behavioral decisions that affect the likelihood of migraine attack onset, emotional responses to migraine attacks, coping strategies used, and treatment adherence. The 33-item Headache-Specific Locus of Control scale is the most widely used measure of locus of control specific to headache yet psychometric evaluations remain limited.

METHODS

Six hundred and ninety-five adults with a diagnosis of migraine from 5 different research studies completed cross-sectional self-report measures including the Headache-Specific Locus of Control scale and measures of quality of life and disability (Migraine-Specific Quality of Life Questionnaire and Migraine Disability Assessment).

RESULTS

Five Headache-Specific Locus of Control components emerged from Horn's Parallel Analysis, Minimum Average Partial test, and Principal Component Analysis (eigenvalues: Presence of Internal = 5.7, Lack of Internal = 4.0, Luck = 2.9, Doctor = 2.0, and Treatment = 1.5). The 33 Headache-Specific Locus of Control items demonstrated adequate internal consistency for total (α = 0.79) and subscale scores (α's = 0.69 to 0.88). This study found preliminary evidence of convergent validity. For example, Lack of Internal (r = -0.12, P = 0.004), Doctor (r = -0.20, P < .001), and Treatment (r = -0.12, P = .004) beliefs were associated with higher overall migraine-specific quality of life impairments.

CONCLUSIONS

The Headache-Specific Locus of Control scale is a reliable and valid measure of headache-specific locus of control. Findings suggest that headache-specific locus of control is more multidimensional than previous conceptualizations and contribute to our understanding of control beliefs as a potential mechanism for migraine treatment.

Barriers to Behavioral Treatment Adherence for Headache: An Examination of Attitudes, Beliefs, and Psychiatric Factors

BACKGROUND/OBJECTIVES

Nonpharmacological interventions, such as biofeedback, cognitive behavioral therapy, and relaxation techniques are Level-A evidence-based treatments for headache. The impact of these interventions is often equivalent to or greater than pharmacological interventions, with fewer side effects. Despite such evidence, the rate of participation in nonpharmacological interventions for headache remains low. Once obstacles to optimizing use of behavioral interventions, such as local access to nonpharmacological treatment and primary headache providers are traversed, identification of barriers contributing to low adherence is imperative given the high levels of disability and cost associated with treating headache disorders. In this review of factors in adults associated with underuse of nonpharmacological interventions, we discuss psychological factors relevant to participation in nonpharmacological treatment, including attitudes and beliefs, motivation for change, awareness of triggers, locus of control, self-efficacy, acceptance, coping styles, personality traits, and psychiatric comorbidities associated with treatment adherence. Finally, future prospects and approaches to optimizing treatment matching and minimizing adherence issues are addressed.

METHODS

An interdisciplinary team conducted this narrative review. Neuropsychologists conducted a literature search during the month of July 2017 using a combination of the keywords ("headache" or "migraine") and ("adherence" or "compliance") or "barriers to treatment" or various "psychological factors" discussed in this narrative review. Content experts, a psychiatrist, and a complementary and integrative health specialist provided additional commentary and input to this narrative review resulting in integration of additional noteworthy studies, book chapters and books.

RESULTS

Various psychological factors, such as attitudes and beliefs, lack of motivation, poor awareness of triggers, external locus of control, poor self-efficacy, low levels of acceptance, and engagement in maladaptive coping styles can contribute to nonadherence.

CONCLUSIONS

To maximize adherence, clinicians can assess and address an individual's level of treatment acceptance, beliefs that may present as barriers, readiness for change, locus of control, self-efficacy and psychiatric comorbidities. Identification of barriers to adherence as well as the application of relevant assessment and intervention techniques have the potential to facilitate adherence and ultimately improve treatment success.

Suicidal ideation, perceived disability, hopelessness and affective temperaments in patients affected by Parkinson's disease

BACKGROUND

Previous studies investigating the risk of suicide in patients with Parkinson's disease (PD) have reported conflicting results. This study evaluated suicide risk in PD and investigated the relationship between suicide risk and perceived disability, hopelessness and affective temperaments in PD.

METHODS

One-hundred and twenty PD patients were consecutively enrolled. The diagnosis of PD was based on clinical criteria. All patients underwent a psychiatric evaluation that included the administration of the Columbia-Suicide Severity Rating Scale, the Italian Perceived Disability Scale, the Beck Hopelessness Inventory and the TEMPS-A questionnaire. The results were compared with those of a control group of 91 patients affected by another chronic disease, ie, open angle glaucoma.

RESULTS

Parkinson's disease patients had higher suicidal ideation, higher perceived disability and lower hyperthymia than the control group. In PD, higher perceived disability was associated with higher current and lifetime suicidal ideation, lower hyperthymia, older age and higher scores on negative temperaments. Suicidal ideation, negative temperaments and hopelessness were risk factors for perceived disability, while hyperthymia was a protective factor for perceived disability.

DISCUSSION

Patients with PD have an increased risk of suicidal ideation. Increased suicidal ideation in PD is associated with the increased perceived disability. A psychiatric assessment that includes the investigation of suicide risk and perceived disability is recommended in patients with PD.

The relationship between alexithymia and headache impact: the role of somatization and pain catastrophizing

PURPOSE

The present study compared psychological factors (i.e., alexithymia, somatization, pain catastrophizing (PC), anxiety, and depression) and QOL for headache patients and headache-free individuals, and examined whether somatization and PC mediate the relationship between alexithymia and headache impact in headache patients.

METHODS

Study participants consisted of 123 headache patients from an outpatient clinic at a university hospital and 124 headache-free individuals in Daegu, Korea. The survey employed the somatization and anxiety subscales of the Symptom Checklist-90-revised, the Patient Health Questionnaire-9, Pain Catastrophizing Scale, Toronto Alexithymia Scale, Short-Form Health survey-8 (SF-8), and the Headache Impact Test-6.

RESULTS

Headache patients showed a higher level of all psychological factors and lower level of two summary scores (physical and mental health) as well as the seven dimensions of the SF-8 compared with headache-free individuals. Examination employing the SPSS Process macro found that the direct effect of alexithymia on headache impact was not significant after controlling for somatization and PC. The total indirect effects of alexithymia on headache impact were significant without anxiety and depression as covariates with the significant indirect effects of alexithymia on headache impact via somatization or via PC as well as via somatization and PC. However, after controlling for anxiety and depression, PC was the only significant pathway through which alexithymia was related to headache impact.

CONCLUSIONS

Headache patients may benefit from interventions aiming at improving psychological factors in order to improve the functioning and QOL of headache patients.

Mindfulness for female outpatients with chronic primary headaches: an internet-based bibliotherapy

Our aim was to investigate effectiveness of mindfulness by bibliotherapy on disability, distress, perceived pain and mindfulness in women with tension headaches and migraines. Primary headaches have been of great interest to mental health researchers because of the high prevalence, as well as significant disability and distress in the affected people. Despite the promising results of in-person treatment and some limitations that such interventions may cause, patients may be encountered with problems when using health care services. The present study is a quasi-experimental randomized design with pre-test, post-test, and control group. The study population consisted of 1396 women with migraine headache referring to headache clinic of Baqiyatallah Hospital in Tehran. Of these, 30 patients (including tboh experimental and control group) were selected by objective sampling method and were randomly assigned to the two groups. The experimental group, in addition to medical treatment as usual, was treated for a period of 8 sessions by Mindfulness-based Stress Reduction Internet-based Bibliotherapy, but the control group used only the medical treatment. The sample had no attritions. Data were collected by the four scales of (DASS-21), Migraine Disability Assessment Test (MIDAS), McGill's Short Form Questionnaire (MPQ-SF), and Mindfulness Inventory (MAAS). We used covariance analysis to analyze the findings in the measured scales. MBSR-IBB treatment had no significant effect on pain sensory dimension (P <0.44), despite improvement of mindfulness (P <0.0001). In contrast, the greatest effect was on the level of disability (P <0.0001). We observed also a significant improvement in distress (P <0.0001). In conclusion, in spite of the presence of headaches, the mindfulness improved the quality of life and reduced the level of mental distress. In addition, using the Internet-based bibliotherapy method, these services can be used with easier access, lower cost, and more flexibility.

A Systematic Review and Meta-Analysis of Migraine and Suicidal Ideation

BACKGROUND

Previous studies have demonstrated an association between migraine and major depressive disorder. However, relatively little is known about the relationship between suicidal ideation, with or without concurrent depression, and migraine.

OBJECTIVE

We conducted a systematic literature review to synthesize the available research focused on investigating the association of migraine with suicidal ideation.

METHODS

Relevant research papers were identified through searches of major electronic databases including PubMed, Embase (Elsevier), Web of Science (Thomson Reuters), PsycINFO (EBSCO), and Google Scholar. We performed a meta-analysis to estimate the pooled unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (95% CI) for the association between migraine and suicidal ideation extracted from each study.

RESULTS

A total of 148,977 participants in 6 studies were included in this analysis. Overall, findings from available studies documented elevated odds of suicidal ideation among individuals with migraines. In unadjusted models, the odds of suicidal ideation was 2.49-fold higher among individuals with migraine (OR, 2.49; 95% CI, 2.34-2.65) compared with those without migraine. In multivariate-adjusted models, the pooled adjusted OR of suicidal ideation was 1.31 (OR, 1.31; 95% CI, 1.10-1.55).

CONCLUSIONS

A meta-analysis of available studies suggests a modest positive association between migraine and suicidal ideation. Further studies allowing for a more comprehensive investigation of the association between migraine and the full range of suicidal behaviors are warranted. A larger and more robust evidence-base may be useful to inform the clinical screening and diagnoses of comorbid conditions in migraineurs.

Maternal Alexithymia and Attachment Style: Which Relationship with Their Children's Headache Features and Psychological Profile?

INTRODUCTION

A growing body of literature has shown an association between somatic symptoms and insecure "attachment style." In a recent study, we found a relationship between migraine severity, ambivalent attachment style, and psychological symptoms in children/adolescents. There is evidence that caregivers' attachment styles and their way of management/expression of emotions can influence children's psychological profile and pain expression. To date, data dealing with headache are scarce. Our aim was to study the role of maternal alexithymia and attachment style on their children's migraine severity, attachment style, and psychological profile.

MATERIALS AND METHODS

We enrolled 84 consecutive patients suffering from migraine without aura (female: 45, male: 39; mean age 11.8 ± 2.4 years). According to headache frequency, children/adolescents were divided into two groups: (1) high frequency (patients reporting from weekly to daily attacks), and (2) low frequency (patients having ≤3 episodes per month). We divided headache attacks intensity into two groups (mild and severe pain). SAFA "Anxiety," "Depression," and "Somatization" scales were used to explore children's psychological profile. To evaluate attachment style, the semi-projective test SAT for patients and ASQ Questionnaire for mothers were employed. Maternal alexithymia traits were assessed by TAS-20.

RESULTS

We found a significant higher score in maternal alexithymia levels in children classified as "ambivalent," compared to those classified as "avoiding" (Total scale: p = 0.011). A positive correlation has been identified between mother's TAS-20 Total score and the children's SAFA-A Total score (p = 0.026). In particular, positive correlations were found between maternal alexithymia and children's "Separation anxiety" (p = 0.009) and "School anxiety" (p = 0.015) subscales. Maternal "Externally-oriented thinking" subscale correlated with children's school anxiety (p = 0.050). Moreover, we found a correlation between TAS-20 Total score and SAFA-D "Feeling of guilt" subscale (p = 0.014). Our data showed no relationship between TAS-20 and ASQ questionnaires and children's migraine intensity and frequency.

CONCLUSION

Maternal alexithymia and attachment style have no impact on children's migraine severity. However, our results suggest that, although maternal alexithymic traits have no causative roles on children's migraine severity, they show a relationship with patients' attachment style and psychological symptoms, which in turn may impact on migraine severity.

Association Between Migraine and Suicidal Behaviors: A Nationwide Study in the USA

BACKGROUND

Recent studies show migraineurs are at an increased risk of developing suicidal behaviors, even after controlling for comorbid depression. However, previous research has not examined the impact of psychiatric mood disorders on suicidal behaviors in migraineurs within a nationally representative sample.

OBJECTIVE

A cross-sectional study was used to investigate the association between migraine and suicidal behaviors and determine whether psychiatric comorbidities modify this association in a nationwide inpatient cohort.

METHODS

We analyzed the Nationwide Inpatient Sample of hospitalizations compiled from USA billing data. Migraine, suicidal behaviors, and psychiatric disorders were identified based on the International Classification of Diseases, 9^th Revision, Clinical Modification diagnosis codes from hospitalization discharges (2007-2012). Weighted national estimates were used to estimate odds ratios (OR) and 95% confidence intervals (CI).

RESULTS

156,172,826 hospitalizations were included, of which 1.4% had a migraine diagnosis and 1.6% had a diagnosis of suicidal behavior. Migraineurs had a 2.07-fold increased odds of suicidal behaviors (95%CI: 1.96-2.19) compared with non-migraineurs. We repeated analyses after stratifying by depression, anxiety, or posttraumatic stress disorder (PTSD). Among hospitalizations with depression, migraine was associated with a 20% reduced odds of suicidal behaviors (95%CI: 0.76-0.85). Among hospitalizations without depression, migraine was associated with 2.35-fold increased odds of suicidal behaviors (95%CI: 2.20-2.51). In stratified analyses, we noted that among hospitalizations with anxiety, migraineurs had slightly increased odds of suicidal behaviors (OR: 1.07, 95%CI: 1.02-1.13). Among hospitalizations without anxiety, migraine was associated with a 2.06-fold increased odds of suicidal behaviors (95%CI: 1.94-2.20). Similarly, in analyses stratified by PTSD, migraine was not associated with an increased risk of suicidal behaviors (OR: 1.00, 95%CI: 0.94-1.07) among those with PTSD. However, the odds of suicidal behaviors were increased among hospitalizations without PTSD (OR: 1.95, 95%CI: 1.84-2.08).

CONCLUSION

Chronic conditions that do not affect the current hospitalization may not have been reported. The presence of psychiatric diagnoses influences associations of suicidal behaviors with migraine in a national inpatient sample. Migraineurs with diagnosed comorbid psychiatric disorders may be receiving care that mitigates their risk for suicidal behaviors.

Opioid Treatment of Migraine: Risk Factors and Behavioral Issues

Migraine can impact every aspect of a person's functioning. Psychological comorbidities, cognitive constructs, and behavioral responses to pain greatly impact the perception of migraine pain, treatment efficacy and outcome, and overall quality of life and functioning. Current considerations for migraine treatment emphasize the utility of the biopsychosocial model in understanding and treating migraine, noting both the importance of addressing psychological factors such as cognitive beliefs as well as psychiatric comorbidities. The guidelines for migraine treatment implicate opioid therapy as a second or third tier treatment. Guidelines and recommendations for the safe use of opioid medications among patients with chronic pain emphasize the importance of screening prior to prescribing opioid medications. Chronic opioid therapy has been shown to further levels of disability, decrease quality of life, and correlate to psychiatric comorbidities, concerns that are already present in migraine patients. While opioid treatment provides an alternative for persons with contraindications for alternative migraine treatments, it is critical that opioids be used sparingly and exclusively in conjunction with comprehensive assessment and integration of psychological treatment.

A Broad Consideration of Risk Factors in Pediatric Chronic Pain: Where to Go from Here?

Pediatric chronic pain is a significant problem associated with substantial functional impairment. A variety of risk factors have been found to be associated with chronic pain in youth. The greatest amount of evidence appears to support that temperament, anxiety, depression, subjective experience of stress, passive coping strategies, sleep problems, other somatic-related problems, and parent and/or family factors are important variables. However, a great deal of this research focuses on a single risk factor or on multiple risk factors in isolation. Much of the literature utilizes older diagnostic criteria and would benefit from replication, larger sample sizes, and comparison across pain disorders. Problems also exist with disagreement across definitions, resulting in inconsistency or unclear use of terms. Furthermore, recent consideration has suggested that outcome measures should include functional disability in addition to pain. A second generation of research is needed to shed light on the complex interactions that likely play a role in the transition from acute to chronic pain. Building on recent calls for changes in research in this area, we propose the next steps for this research, which involve consideration of both biopsychosocial and developmental contexts.

Psychological Considerations in the Assessment and Treatment of Pain in Neurorehabilitation and Psychological Factors Predictive of Therapeutic Response: Evidence and Recommendations from the Italian Consensus Conference on Pain in Neurorehabilitation

Background: In order to provide effective care to patients suffering from chronic pain secondary to neurological diseases, health professionals must appraise the role of the psychosocial factors in the genesis and maintenance of this condition whilst considering how emotions and cognitions influence the course of treatment. Furthermore, it is important not only to recognize the psychological reactions to pain that are common to the various conditions, but also to evaluate how these syndromes differ with regards to the psychological factors that may be involved. As an extensive evaluation of these factors is still lacking, the Italian Consensus Conference on Pain in Neurorehabilitation (ICCPN) aimed to collate the evidence available across these topics.

Objectives: To determine the psychological factors which are associated with or predictive of pain secondary to neurological conditions and to assess the influence of these aspects on the outcome of neurorehabilitation.

Methods: Two reviews were performed. In the first, a PUBMED search of the studies assessing the association between psychological factors and pain or the predictive value of these aspects with respect to chronic pain was conducted. The included papers were then rated with regards to their methodological quality and recommendations were made accordingly. In the second study, the same methodology was used to collect the available evidence on the predictive role of psychological factors on the therapeutic response to pain treatments in the setting of neurorehabilitation.

Results: The first literature search identified 1170 results and the final database included 189 articles. Factors such as depression, anxiety, pain catastrophizing, coping strategies, and cognitive functions were found to be associated with pain across the various conditions. However, there are differences between chronic musculoskeletal pain, migraine, neuropathy, and conditions associated with complex disability with regards to the psychological aspects that are involved. The second PUBMED search yielded 252 studies, which were all evaluated. Anxiety, depression, pain catastrophizing, coping strategies, and pain beliefs were found to be associated to different degrees with the outcomes of multidisciplinary programs, surgery, physical therapies, and psychological interventions. Finally, sense of presence was found to be related to the effectiveness of virtual reality as a distraction tool.

Conclusions: Several psychological factors are associated with pain secondary to neurological conditions and should be acknowledged and addressed in order to effectively treat this condition. These factors also predict the therapeutic response to the neurorehabilitative interventions.

The efficiency of botulinum toxin type A for the treatment of masseter muscle pain in patients with temporomandibular joint dysfunction and tension-type headache

BACKGROUND

Temporomandibular joint dysfunction are often accompanied by symptoms of headache such as tension-type headache which is the most frequent spontaneous primary headache. Masseter muscle pain is commonly reported in this group. The purpose of the study was to assess the efficiency of intramuscular botulinum toxin type A injections for treating masseter muscle pain in patients with temporomandibular joint dysfunction and tension-type headache.

METHODS

This prospective outcome study consisted of 42 subjects of both genders aged 19-48 years diagnosed with masseter muscle pain related to temporomandibular joint dysfunction and tension-type headache. The subjects were treated by the intramuscular injection of 21 U (mice units) of botulinum toxin type A (Botox, Allergan) in the area of the greatest cross-section surface of both masseter bellies. Pain intensity was evaluated using visual analogue scale (VAS) and verbal numerical rating scale (VNRS) 1 week before the treatment and 24 weeks after the treatment. The obtained data were analyzed using the Wilcoxon matched pairs test (p ≤ 0,005).

RESULTS

The results of this study showed a decrease in the number of referred pain episodes including a decrease in pain in the temporal region bilaterally, a reduction of analgesic drugs intake as well as a decrease in reported values of VAS and VNRS after injections (p = 0,000).

CONCLUSIONS

The intramuscular botulinum toxin type A injections have been an efficient method of treatment for masseter muscle pain in patients with temporomandibular joint dysfunction and tension-type headache.

Patients' experiences of a behavioural intervention for migraine headache: a qualitative study

BACKGROUND

Migraine headache has a high prevalence and a severe impact on personal, social and work life, forming a significant burden on patients, service providers and society. There is some evidence of the effectiveness of behavioural interventions to supplement drug therapy but a recognised need to identify an effective minimal contact approach to enhance access and provide a model for use in publicly funded health systems. This study uses in-depth interviews to examine patients' experience and responses to a behavioural intervention with relaxation and CBT components delivered in three individual therapist sessions with follow-up.

METHODS

Qualitative study of 20 adults aged 18-75 years in London, UK, with clinically diagnosed migraine and at least four headache days per month. Semi-structured and tape recorded interviews were held post intervention based on a topic guide. Transcripts were coded and charted for all participants and analysed thematically.

RESULTS

The majority of participants cited the impacts of migraine and a desire for additional non-drug treatment as their main reasons for taking part and almost all completed the course. They valued contact with the therapist and almost all reported benefiting from the therapy. Post intervention they used those techniques they found most beneficial and implemented them flexibly in their daily life to reduce stress and risks of migraine or to respond to migraine. Relaxation training (deep breathing) was easily adopted and often used post intervention. The CBT components were mainly viewed positively but regarded as more challenging to learn and implement.

CONCLUSIONS

Patients' selectively identified and employed the techniques learned as 'tools' to assist in preventing and managing their migraines, with reported benefits supporting the development of minimal contact behavioural therapy to increase accessibility for adults with migraine headache and the conduct of a definitive trial.

Migraine equivalents and related symptoms, psychological profile and headache features: which relationship?

Background

Migraine equivalents are common clinical conditions in children suffering from headache. Very few studies dealt with the psychological profile of children/adolescents with migraine equivalents. Our main aim was to compare the psychological profile between migraine children with and without migraine equivalents. Moreover, as secondary aim, exclusively in children with migraine equivalents, we investigated the possible relationship between migraine attack frequency and intensity and psychological factors.

Methods

We enrolled 136 young migraineurs. They were divided in two groups (patients with and without migraine equivalents). The psychological profile was assessed by means of SAFA Anxiety and Somatization questionnaires.

Results

Migraine equivalents were present in 101 patients (74.3 %). Anxiety (p = 0.024) and somatization (p = 0.001) levels, but not hypochondria (p = 0.26), were higher in patients with migraine equivalents. In children with migraine equivalents, a low frequency of attacks was related to separation anxiety (p = 0.034).

Conclusions

Migraine equivalents patients tend to feel more fearful and to experience more shyness. This, together with the tendency to somatization, may lead them to become vigilant in attachment relationships with their caregivers.

Negative affectivity, emotion regulation, and coping in migraine and probable migraine: a New Zealand case-control study

BACKGROUND

Migraine is a prevalent and disabling health condition. While there have been some suggestions that personality may be linked to migraine incidence, dose-response links to disability or impact are yet to be conducted and multivariate analyses are uncommon.

PURPOSE

The purposes of this study are to evaluate the personality characteristics differentiating migraine and probable migraine sufferers from matched controls in multivariate models and assess the possibility of a dose-response relationship.

METHODS

Fifty migraine sufferers and 50 age-, sex-, and ethnicity-matched controls in New Zealand completed personality measures including negative affectivity, coping, and monitoring-blunting.

RESULTS

Logistic regressions indicated that migraine status was concurrently predicted by Type D negative affectivity, more frequent venting and planning coping, and lower monitoring. There was little evidence to suggest a consistent dose-response type effect of personality on migraine; lower impact and disability were associated with greater openness to experiences, acceptance, and behavioural disengagement.

CONCLUSIONS

A personality profile characterised by moderate levels of negative emotion and irritability together with failures in inhibitory self-regulation may be associated with an increased risk of strict and probable migraine.

Factors associated with disability and impact of tension-type headache: findings of the Korean headache survey

BACKGROUND

Although mostly mild in symptom severity, tension-type headache (TTH) can cause disability. However, factors associated with disability of TTH have been rarely reported. This study sought to assess the factors associated with TTH-related disability and impact.

METHODS

We analyzed data form the Korean Headache Survey, a nation-wide survey regarding headache in all Korean adults aged 19-69 years. TTH-related disability was measured by surveying actual disability and Headache Impact Test-6 (HIT-6). Actual disability was defined as having one or more days of activity restriction or missed activity due to headache in the last 3 months. The HIT-6 score ≥ 50 was regarded as significant headache impact associated with TTH. We assessed factors associated with TTH-related disability and impact using logistic regression analyses adjusting for sociodemographic variables and headache characteristics.

RESULTS

Among 1507 individuals, the 1-year prevalence rate of TTH was 30.7% (n = 463), of which 4.8% reported actual disability and 21.3% had headache impact, respectively. In univariate analyses, sociodemographic variables were not associated with actual disability and headache impact, respectively. There were relationships between several headache characteristics and actual disability/headache impact. After adjustment of potential confounders, moderate headache intensity was correlated with actual disability (odds ratio [OR]: 4.41, 95% confidence interval [CI]: 1.46-13.27), while an inverse association was observed between no aggravation by routine activity and actual disability (OR: 0.32, 95% CI: 0.12-0.88). Multivariate analyses showed that ORs for headache impact were increased in those with higher headache frequency (OR: 2.54, 95% CI: 1.47-4.39 for 1-14 days/month; OR: 23.83, 95% CI: 5.46-104.03 for ≥ 15 days/month), longer headache time duration (OR: 1.84, 95% CI: 1.04-3.25 for ≥ 1 and < 4 hours; OR: 2.44 95% CI: 1.17-5.11 for ≥ 4 hours), and phonophobia (OR: 1.73, 95% CI: 1.02-2.95), whereas decreased in those with no aggravation by routine activity (OR: 0.32, 95% CI: 0.12-0.88).

CONCLUSIONS

Several headache characteristics were associated with actual disability and headache impact among TTH individuals. Our findings suggest that there needs to be consideration careful of troublesome headache characteristics for TTH individuals suffering from disability and impact.

Psychological evaluation of a primary headache patient

A patient's experience with headache is influenced, not only by the frequency and pain of the attacks, but also by the patient's perception of the controllability of the attacks, their willingness to engage in activities despite attacks and their attitude towards the medications used to treat the headaches. Clinicians are often aware of the need to evaluate their patients for the existence of comorbid psychiatric disorders but may be less aware of the importance of these nonpathological beliefs/attitudes that are present to some degree in every headache sufferer. This article gives an overview (by no means exhaustive) of several important psychological constructs, with an emphasis on how these constructs can be assessed in headache patients using freely available paper-pencil questionnaires.

Clinical features, anger management and anxiety: a possible correlation in migraine children

BACKGROUND

Psychological factors can increase severity and intensity of headaches. While great attention has been placed on the presence of anxiety and/or depression as a correlate to a high frequency of migraine attacks, very few studies have analyzed the management of frustration in children with headache. Aim of this study was to analyze the possible correlation between pediatric migraine severity (frequency and intensity of attacks) and the psychological profile, with particular attention to the anger management style.

METHODS

We studied 62 migraineurs (mean age 11.2 ± 2.1 years; 29 M and 33 F). Patients were divided into four groups according to the attack frequency (low, intermediate, high frequency, and chronic migraine). Pain intensity was rated on a 3-levels graduate scale (mild, moderate and severe pain). Psychological profile was assessed by Picture Frustration Study test for anger management and SAFA-A scale for anxiety.

RESULTS

We found a relationship between IA/OD index (tendency to inhibit anger expression) and both attack frequency (r = 0.328, p = 0.041) and intensity (r = 0.413, p = 0.010). When we analyzed the relationship between anxiety and the headache features, a negative and significant correlation emerged between separation anxiety (SAFA-A Se) and the frequency of attacks (r = -0.409, p = 0.006). In our patients, the tendency to express and emphasize the presence of the frustrating obstacle (EA/OD index) showed a positive correlation with anxiety level (“Total anxiety” scale: r = 0.345; p = 0.033).

CONCLUSIONS

Our results suggest that children suffering from severe migraine tend to inhibit their angry feelings. On the contrary, children with low migraine attack frequency express their anger and suffer from separation anxiety.

Validation of criterion-based patient assignment and treatment effectiveness of a multidisciplinary modularized managed care program for headache

This prospective observational study evaluates the validity of an algorithm for assigning patients to a multidisciplinary modularized managed care headache treatment program. N = 545 chronic headache sufferers [migraine (53.8 %), migraine + tension type (30.1 %), tension type (8.3 %) or medication overuse headache (6.2 %), other primary headaches (1.5 %)] were assigned to one of four treatment modules differing with regard to the number and types of interventions entailed (e.g., medication, psychological intervention, physical therapy, etc.). A rather simple assignment algorithm based on headache frequency, medication use and psychiatric comorbidity was used. Patients in the different modules were compared with regard to the experienced burden of disease. 1-year follow-up outcome data are reported (N = 160). Headache frequency and analgesic consumption differed significantly among patients in the modules. Headache-related disability was highest in patients with high headache frequency with/without medication overuse or psychiatric comorbidity (modules 2/3) compared to patients with low headache frequency and medication (module 0). Physical functioning was lowest in patients with chronic headache regardless of additional problems (modules 1/2/3). Psychological functioning was lowest in patients with severe chronicity with/without additional problems (module 2/3) compared to headache suffers with no/moderate chronicity (module 0/1). Anxiety or depression was highest in patients with severe chronicity. In 1-year follow-up, headache frequency (minus 45.3 %), consumption of attack-aborting drugs (minus 71.4 %) and headache-related disability decreased (minus 35.9 %). Our results demonstrate the clinical effectiveness and the criterion validity of the treatment assignment algorithm based on headache frequency, medication use and psychiatric comorbidity.

Placebo and other psychological interactions in headache treatment

We present a theory according which a headache treatment acts through a specific biological effect (when it exists), a placebo effect linked to both expectancy and repetition of its administration (conditioning), and a non-specific psychological effect. The respective part of these components varies with the treatments and the clinical situations. During antiquity, suggestions and beliefs were the mainstays of headache treatment. The word placebo appeared at the beginning of the eighteenth century. Controversies about its effect came from an excessive interpretation due to methodological bias, inadequate consideration of the variation of the measure (regression to the mean) and of the natural course of the disease. Several powerful studies on placebo effect showed that the nature of the treatment, the associated announce, the patients' expectancy, and the repetition of the procedures are of paramount importance. The placebo expectancy is associated with an activation of pre-frontal, anterior cingular, accumbens, and periacqueducal grey opioidergic neurons possibly triggered by the dopaminergic meso-limbic system. In randomized control trials, several arms design could theoretically give information concerning the respective part of the different component of the outcome and control the natural course of the disease. However, for migraine and tension type headache attacks treatment, no three arm (verum, placebo, and natural course) trial is available in the literature. Indirect evidence of a placebo effect in migraine attack treatment, comes from the high amplitude of the improvement observed in the placebo arms (28% of the patients). This figure is lower (6%) when using the harder criterium of pain free at 2 h. But these data disregard the effect of the natural course. For prophylactic treatment with oral medication, the trials performed in the last decades report an improvement in 21% of the patients in the placebo arms. However, in these studies the duration of administration was limited, the control of attacks uncertain as well as the evolution of the co-morbid psycho-pathology. Considering the reviews and meta-analysis of complex prophylactic procedures, it must be concluded that their effect is mostly linked to a placebo and non-specific psychological effects. Acupuncture may have a slight specific effect on tension type headache, but not on migraine. Manual therapy studies do not exhibit difference between manipulation, mobilization, and controls; touch has no proven specific effect. A comprehensive efficacy review of biofeedback studies concludes to a small specific effect on tension type headache but not on migraine. A review of behavioral treatment conclude to an interesting mean improvement but did not demonstrated a specific effect with the exception of a four arm study including a pseudo meditation control group. Expectation-linked placebo, conditioning, and non-specific psychological effects vary according clinical situations and psychological context; likely low in RCT, high after anempathic medical contact, and at its maximum with a desired charismatic healer. The announcements of doctors strongly influence the beliefs of patients, and in consequence their pain and anxiety sensibilities; this modulates the amplitude of the placebo and the non-specific psychological effects and is therefore a major determinant of the therapeutic success. Furthermore, any repetitive contact, even through a placebo, may interfere positively with the psychopathological co-morbidity. One has to keep in mind that the non-specific psychological interactions play a major role in the improvement of the majority of the headache sufferers.

Psychopathology and quality of life burden in chronic daily headache: influence of migraine symptoms

The aim of this study is to compare the psychopathology and the quality of life of chronic daily headache patients between those with migraine headache and those with tension-type headache. We enrolled 106 adults with chronic daily headache (CDH) who consulted for the first time in specialised centres. The patients were classified according to the IHS 2004 criteria and the propositions of the Headache Classification Committee (2006) with a computed algorithm: 8 had chronic migraine (without medication overuse), 18 had chronic tension-type headache (without medication overuse), 80 had medication overuse headache and among them, 43 fulfilled the criteria for the sub-group of migraine (m) MOH, and 37 the subgroup for tension-type (tt) MOH. We tested five variables: MADRS global score, HAMA psychic and somatic sub-scales, SF-36 psychic, and somatic summary components. We compared patients with migraine symptoms (CM and mMOH) to those with tension-type symptoms (CTTH and ttMOH) and neutralised pain intensity with an ANCOVA which is a priori higher in the migraine group. We failed to find any difference between migraine and tension-type groups in the MADRS global score, the HAMA psychological sub-score and the SF36 physical component summary. The HAMA somatic anxiety subscale was higher in the migraine group than in the tension-type group (F(1,103) = 10.10, p = 0.001). The SF36 mental component summary was significantly worse in the migraine as compared with the tension-type subgroup (F(1,103) = 5.758, p = 0.018). In the four CDH subgroups, all the SF36 dimension scores except one (Physical Functioning) showed a more than 20 point difference from those seen in the adjusted historical controls. Furthermore, two sub-scores were significantly more affected in the migraine group as compared to the tension-type group, the physical health bodily pain (F(1,103) = 4.51, p = 0.036) and the mental health (F(1,103) = 8.17, p = 0.005). Considering that the statistic procedure neutralises the pain intensity factor, our data suggest a particular vulnerability to somatic symptoms and a special predisposition to develop negative pain affect in migraine patients in comparison to tension-type patients.

Psychiatric comorbidities and migraine chronification

A growing body of literature has implicated comorbid psychopathology as a potential risk factor for the chronification of migraine. Of the psychiatric disorders, depressive and anxiety disorders have been most consistently associated with the chronification of migraine. A shared dysfunction of the serotonergic system, medication overuse, and psychological factors have been proposed to mediate this relationship, although the responsible mechanisms are still largely unclear. This article overviews literature on psychiatric comorbidities and migraine chronification, considers mechanisms underlying this relationship, and notes directions for future clinical and empirical work.

Migraine education improves quality of life in a primary care setting

OBJECTIVE

The objective of this study was to evaluate the effectiveness of the Mercy Migraine Management Program (MMMP), an educational program for physicians and patients. The primary outcome was change in headache days from baseline at 3, 6, and 12 months. Secondary outcomes were changes in migraine-related disability and quality of life, worry about headaches, self-efficacy for managing migraines, emergency room (ER) visits for headache, and satisfaction with headache care.

BACKGROUND

Despite progress in the understanding of the pathophysiology of migraine and development of effective therapeutic agents, many practitioners and patients continue to lack the knowledge and skills to effectively manage migraine. Educational efforts have been helpful in improving the quality of care and quality of life for migraine sufferers. However, little work has been performed to evaluate these changes over a longer period of time. Also, there is a paucity of published research evaluating the influence of education about migraine management on cognitive and emotional factors (for example, self-efficacy for managing headaches, worry about headaches).

METHODS

In this open-label, prospective study, 284 individuals with migraine (92% female, mean age = 41.6) participated in the MMMP, an educational and skills-based program. Of the 284 who participated in the program, 228 (80%) provided data about their headache frequency, headache-related disability (as measured by the Headache Impact Test-6 (HIT-6), migraine-specific quality of life (MSQ), worry about headaches, self-efficacy for managing headaches, ER visits for headaches, and satisfaction with care at 4 time points over 12 months (baseline, 3 months, 6 months, 12 months).

RESULTS

Overall, 46% (106) of subjects reported a 50% or greater reduction in headache frequency. Over 12 months, patients reported fewer headaches and improvement on the HIT-6 and MSQ (all P < .001). The improvement in headache impact and quality of life was greater among those who had more worry about their headaches at baseline. There were also significant improvements in "worry about headaches,""self-efficacy for managing headaches," and "satisfaction with headache care."

CONCLUSION

The findings demonstrate that patients participating in the MMMP reported improvements in their headache frequency as well as the cognitive and emotional aspects of headache management. This program was especially helpful among those with high amounts of worry about their headaches at the beginning of the program. The findings from this study are impetus for further research that will more clearly evaluate the effects of education and skill development on headache characteristics and the emotional and cognitive factors that influence headache.

Chronic headache: the role of the psychologist

The role of the psychologist in chronic headache needs to be tailored to the patient's presentation. For some patients, psychological issues need to be directly addressed (eg, psychiatric comorbidity, difficulties coping with headache, significant problems with sleep and/or stress, medication overuse, and history of abuse). Other situations (eg, patients' beliefs about their readiness to change ability to actively manage headaches, medication adherence, and managing triggers) involve behavioral/psychological principles even when there is no direct contact with a psychologist. This article reviews the literature on the importance of psychological issues in headache management and provides suggestions for how to address behavioral and cognitive factors and their potential for improved headache care.

Do psychiatric comorbidities influence headache treatment outcomes? Results of a naturalistic longitudinal treatment study

This study examined if the presence of one or more psychiatric disorders influences headache treatment outcomes in patients in headache specialty treatment centers. Using a naturalistic, longitudinal design, 223 patients receiving preventive therapy for headache disorders completed 30-day daily diaries that assessed headache days/month and severity at acute therapy baseline and 6-month evaluation and also provided data on headache disability and quality of life at acute therapy baseline, preventive therapy initiation, preventive therapy adjustment, and 6-month evaluation visits. Psychiatric diagnoses were determined using the Primary Care Evaluation for Mental Disorders (PRIME MDs). Of the 223 patients, 34% (n = 76) had no psychiatric disorder, 21% (n = 46) were diagnosed with Depression-Only; 13% (n = 29) were diagnosed with Anxiety-Only; and 32% (n = 72) were diagnosed with Depression-and-Anxiety. Prior to initiating new preventive therapy, patients with one or more psychiatric disorders reported more frequent and disabling headaches and poorer life quality compared to patients with no psychiatric disorders. Rates of improvement in headache days/month, disability, and quality of life were significant and comparable across the four groups. Contrary to clinical wisdom, patients with psychiatric disorders respond very favorably to contemporary headache treatments administered in headache specialty treatment centers.

Spinal segmental stabilisation exercises for chronic low back pain: programme adherence and its influence on clinical outcome

Exercise rehabilitation is one of the few evidence-based treatments for chronic non-specific low back pain (cLBP), but individual success is notoriously variable and may depend on the patient's adherence to the prescribed exercise regime. This prospective study examined factors associated with adherence and the relationship between adherence and outcome after a programme of physiotherapeutic spine stabilisation exercises. A total of 32/37 patients with cLBP completed the study (mean age, 44.0 (SD = 12.3) years; 11/32 (34%) male). Adherence to the 9-week programme was documented as: percent attendance at therapy, percent adherence to daily home exercises (patient diary) and percent commitment to rehabilitation (Sports Injury Rehabilitation Adherence Scale (SIRAS)). The average of these three measures formed a multidimensional adherence index (MAI). Psychological disturbance, fear-avoidance beliefs, catastrophising, exercise self-efficacy and health locus of control were measured by questionnaire; disability in everyday activities was scored with the Roland-Morris disability scale and back pain intensity with a 0-10 graphic rating scale. Overall, adherence to therapy was very good (average MAI score, 85%; median (IQR), 89 (15)%). The only psychological/beliefs variable showing a unique significant association with MAI was exercise self-efficacy (Rho = 0.36, P = 0.045). Pain intensity and self-rated disability decreased significantly after therapy (each P < 0.01). Adherence to home exercises showed a moderate, positive correlation with the reduction in average pain (Rho = 0.54, P = 0.003) and disability (Rho = 0.38, P = 0.036); higher MAI scores were associated with greater reductions in average pain (Rho = 0.48, P = 0.008) and a (n.s.) tendency for greater reductions in disability (Rho = 0.32, P = 0.07) Neither attendance at therapy nor SIRAS were significantly related to any of the outcomes. The benefits of rehabilitation depended to a large extent on the patient's exercise behaviour outside of the formal physiotherapy sessions. Hence, more effort should be invested in finding ways to improve patients' motivation to take responsibility for the success of their own therapy, perhaps by increasing exercise self-efficacy. Whether the "adherence-outcome" interaction was mediated by improvements in function related to the specific exercises, or by a more "global" effect of the programme, remains to be examined.

Anxiety disorders and migraine intractability and progression

Comorbid psychopathology has been implicated as a risk factor for the chronification and progression of migraine. Although past research has focused principally on depression and migraine, recent research consistently has confirmed that a disproportionate number of migraineurs suffer from one or more comorbid anxiety disorders. Moreover, this research has implicated anxiety disorders as factors potentially associated with migraine intractability and progression; growing evidence suggests that anxiety disorders may be even more prognostically significant than depression. This article summarizes these recent developments, considers mechanisms underlying this comorbidity, discusses strategies for assessing and managing comorbid anxiety, and notes directions for future clinical and empiric work.
