Efficacy of psychological treatment for headache disorder: a systematic review and meta-analysis

2023 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guideline for the Management of Headache

DESCRIPTION

Headache medicine and therapeutics evidence have been rapidly expanding and evolving since the 2020 U.S. Department of Veterans Affairs (VA) and U.S. Department of Defense (DoD) clinical practice guideline (CPG) for the management of headache. Therefore, the CPG was revised in 2023, earlier than the standard 5-year cycle. This article reviews the 2023 CPG recommendations relevant to primary care clinicians for treatment and prevention of migraine and tension-type headache (TTH).

METHODS

Subject experts from the VA and the DoD developed 12 key questions, which guided a systematic search using predefined inclusion and exclusion criteria. After reviewing evidence from 5 databases published between 6 March 2019 and 16 August 2022, the work group considered the strength and quality of the evidence, patient preferences, and benefits versus harms on critical outcomes before making consensus recommendations.

RECOMMENDATIONS

The revised CPG includes 52 recommendations on evaluation, pharmacotherapy, invasive interventions, and nonpharmacologic interventions for selected primary and secondary headache disorders. In addition to triptans and aspirin-acetaminophen-caffeine, newer calcitonin gene-related peptide (CGRP) inhibitors (gepants) are options for treatment of acute migraine. Medications to prevent episodic migraine (EM) include angiotensin-receptor blockers, lisinopril, magnesium, topiramate, valproate, memantine, the newer CGRP monoclonal antibodies, and atogepant. AbobotulinumtoxinA can be used for prevention of chronic migraine but not EM. Gabapentin is not recommended for prevention of EM. Ibuprofen (400 mg) and acetaminophen (1000 mg) can be used for treatment of TTH, and amitriptyline for prevention of chronic TTH. Physical therapy or aerobic exercise can be used in management of TTH and migraines.

"I am now on 'speaking terms' with my migraine monster" - patient experiences in acceptance-based cognitive behavioral therapy delivered via the internet for migraine: a randomized controlled pilot study using a mixed-method approach

Migraine is a common neurological disorder globally. Migraines, with or without aura, are episodic and recurring with symptom-free periods. Frequent and prolonged attacks can lead to chronic migraine. This pilot randomized controlled trial (RCT) aimed to evaluate feasibility of therapist-guided, acceptance-based internet cognitive behavioral therapy (iCBT) as an adjunct to standard medical care for migraine patients in Swedish primary healthcare settings using a mixed methods approach. Participants (treatment n = 15, control n = 14) underwent qualitative and quantitative assessments to evaluate feasibility, acceptance, and initial treatment effects. Interviews with participants (n = 7) indicate that most participants had struggled with migraines for decades and expressed dissatisfaction with the limited medical care. They found the flexible, digital format particularly helpful, praising its accessibility and structured learning. While they appreciated the comprehensive content, some faced challenges with the psychological language and the program pace. Post-treatment, participants reported emotional and behavioral changes, and better migraine management. Seventy-two percent of the 29 participants completed both baseline and 3-month follow-up measures. On average, participants completed 7.7 modules, with 60% completing all 10 modules. Promising effect size indicated a reduction in migraine days during the three-month follow-up. Both qualitative and quantitative data support the feasibility and acceptability of the intervention in primary care settings.

Non-invasive Management of Head and Neck Neuralgia: A Literature Review

Head and neck neuralgia is a prevalent condition impacting millions worldwide, necessitating both invasive and non-invasive management strategies. This review focuses specifically on non-invasive approaches. Using the International Classification of Headache Disorders (ICHD-3), we categorized neuralgia causing head and neck pain to structure our literature search. Our review identified several non-invasive management techniques, including physiotherapy, pharmacological treatments, Pulsed Radiofrequency, local anesthesia blocks, Botulinum toxin injections, and non-invasive neuromodulation. This review highlights various effective non-invasive strategies for managing head and neck neuralgias, supported by studies published until 2023. These findings emphasize the clinical relevance of tailoring treatment plans to individual patient needs, considering the specific type of neuralgia and optimizing outcomes in clinical practice.

Psychological treatments for temporomandibular disorder pain-A systematic review

OBJECTIVE

Temporomandibular disorders (TMD) are common. They affect abilities for carrying out daily tasks and influence different psychological aspects. In addition to standard treatment, psychological treatments have been suggested. The aim was to investigate the effects of psychological treatments on patients with painful TMD in a short- and long-term perspective.

MATERIALS AND METHODS

An electronic search was conducted in the databases MEDLINE, CINAHL, EMBASE, the Cochrane Central Registry of Controlled Trials (CENTRAL), and Web of Science for randomized clinical trials (RCTs) reporting psychological interventions for TMD. Registered beforehand in PROSPERO (CRD42022320106). In total, 18 RCTs were included; six RCTs that could be used in the meta-analysis, and all 18 RCTs were used in the narrative synthesis. Risk of bias was assessed by the Cochrane's tool for assessing risk of bias and certainty of evidence by GRADE.

RESULTS

The narrative synthesis indicates that psychological treatment options seem equivalent to standard treatment for painful TMD. The meta-analysis showed that a combination of psychological treatment and standard treatment and manual treatment (very low-quality evidence) are significantly better in pain reduction than just counselling and standard treatments of TMD.

CONCLUSION

This study indicates that psychological treatments seem to reduce pain intensity in individuals with painful TMD, and that the effect seems to be equally good as standard treatment. However, a combination of psychological treatments and standard treatments seems to have an even better effect. This indicates that psychological treatments are promising as an additional treatment approach for painful TMDs.

Effects of Dry Needling on Active Myofascial Trigger Points and Pain Intensity in Tension-Type Headache: A Randomized Controlled Study

Tension-type headache is the most prevalent type of headache and is commonly associated with myofascial pain syndrome and the presence of active myofascial trigger points. This randomized controlled trial aimed to assess the impact of dry needling on the total number of active trigger points, pain intensity, and perceived clinical change in tension-type headache subjects. Thirty-two subjects were randomly assigned to the control and dry needling groups. The presence of active trigger points in 15 head and neck muscles, the headache intensity, and the perceived clinical change were evaluated. A single dry needling technique was administered at each active trigger point across three sessions. Significant differences were observed in the post-treatment measures favouring the dry needling group, including reductions in the headache intensity scores (p = 0.034) and the total number of active trigger points (p = 0.039). Moreover, significant differences in the perception of clinical change were found between the control and treatment groups (p = 0.000). Dry needling demonstrated positive effects in reducing the number of active trigger points and improving the short-term headache intensity in tension-type headache patients. A single dry needling session applied in the cranio-cervical area resulted in a self-perceived improvement compared to the control subjects.

Headaches treatment with EMG biofeedback: a focused systematic review and meta-analysis

INTRODUCTION

The aim of this paper was to present an up-to-date evaluation of the efficacy of EMG-biofeedback (EMG-BFB) for primary headaches and to address possible mediators of outcome.

EVIDENCE ACQUISITION

PubMed, Scopus, Embase and Pedro databases were searched from inception to May 1, 2023. All randomized controlled trials (RCT) studies using an EMG-BFB to treat headache have been included in this systematic review. The current systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations and was registered in the PROSPERO database (CRD42022312827). Methodological quality was assessed through the Risk of Bias tool 2 (RoB 2). The effect sizes and 95% confidence interval (CI) were calculated by random-effect models on frequency, intensity, and duration variables. Egger regression and the Begg-Mazumdar rank correlation test were used for publication bias.

EVIDENCE SYNTHESIS

A total of 3059 articles were identified through the database searches. 29 articles, involving 1342 participants, met the inclusion criteria for the systematic review; of them, 4 were included in the meta-analysis. Ten studies reported a significant improvement in the EMG-BFB group with respect to the control group. Meta-analyses show a reduction in the intensity of attacks in patients subjected to EMG-BFB (ES 0.21 [(95% CI=-0.02; 0.44), P value=0.07] based on 293 patients).

CONCLUSIONS

EMG-BFB represents a non-pharmacological approach to headache treatment as shown via qualitative synthesis, despite not impressive results, this technique can be particularly useful in paediatric or in adult patients who cannot undergo drug therapies. Quantitative synthesis revealed a promising effect in the intensity of headaches attacks. Moreover, no significant effect was found about the effectiveness of EMG-BFB in the reduction of frequency and durations of headache attacks. Future studies with new multimodal technologic assessment and following RCT guidelines can unmask the potentiality of EMG-BFB in the treatment of headache.

Debate: differences and similarities between tension-type headache and migraine

Tension-type headache (TTH) and migraine are two common primary headaches distinguished by clinical characteristics according to the 3^rd edition of the International Classification of Headache Disorders. Migraine is identified by specific features such as being more prevalent in females, being aggravated by physical activity, certain genetic factors, having photophobia, phonophobia, nausea, vomiting, or aura, and responding to specific drugs. Nonetheless, TTH and migraine share some common characteristics, such as onset occurring in the 20 s, and being triggered by psychological factors like stress, moderate pain severity, and mild nausea in chronic TTH. Both conditions involve the trigeminovascular system in their pathophysiology. However, distinguishing between TTH and migraine in clinical practice, research, and epidemiological studies can be challenging, as there is a lack of specific diagnostic tests and biomarkers. Moreover, both conditions may coexist, further complicating the diagnostic process. This review aims to explore the similarities and differences in the pathophysiology, epidemiology, burden and disability, comorbidities, and responses to pharmacological and non-pharmacological treatments of TTH and migraine. The review also discusses future research directions to address the diagnostic challenges and improve the understanding and management of these conditions.

Effects on neuromodulation, acupuncture, and aerobic exercises on migraine and tension-type headache outcomes: A systematic review and meta-analysis

BACKGROUND

Headache disorders are common diseases that cause a social burden. This systematic review and meta-analysis aimed to evaluate the effects of various non-pharmacological treatments to address or prevent acute headaches, including neuromodulation, acupuncture, and aerobic exercises in patients with episodic migraine and tension-type headache (TTH).

METHODS

We performed a systematic search of the electronic databases PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, WANFANG MEDICINE ONLINE, and Chinese Medical Journal database using Stata/SE 14.0 to obtain weighted mean differences (WMDs). The outcomes included monthly headache days, headache intensity, headache duration, days per month of acute medication use, and the Medical Outcomes Study 36-Item Short-Form Health Survey.

RESULTS

Of 872 identified articles, 27 were included in the meta-analysis. Neuromodulation was associated with reduced headache days (WMD: -1.274, 95% CI [-1.914, -0.634], P < .001), duration (WMD: -2.2, 95% CI [-3.32, -0.107], P < .001) and medication consumption (WMD: -1.808, 95% CI [-2.546, -1.071], P < .001) in cases of migraine. Acupuncture was associated with the alleviation of headache days (WMD: -0.677, 95% CI [-0.932, -0.422], P < .001) and intensity (WMD: -0.893, 95% CI [-1.573, -0.212], P = .01) in cases of migraine and acute medication use (WMD: -3.29, 95% CI [-4.86, -1.72], P < .001) in cases of TTH. Aerobic exercise was associated with reduced headache duration (WMD: -5.1, 95% CI [-8.97, -1.22], P = .01) in cases of TTH. The risk of bias for included articles was moderate.

CONCLUSIONS

There is low- and moderate-quality evidence that neuromodulation, acupuncture, and aerobic exercises are associated with attenuated headache symptoms in patients with episodic migraine or TTH. However, high-quality studies are needed to draw more detailed conclusions.

Migraine in the context of chronic primary pain, chronic overlapping pain disorders, and functional somatic disorders: A narrative review

OBJECTIVE

To contextualize migraine as the most common primary headache disorder in relation to other chronic primary pain and non-pain functional somatic and mental conditions.

BACKGROUND

Migraine is increasingly understood as a sensory processing disorder within a broader spectrum of symptom disorders. This has implications for diagnosis and treatment.

METHOD

Narrative review based on a search of the literature of the last 15 years on the overlap of migraine with other symptom disorders.

RESULTS

Migraine as the prototypical primary headache disorder not only comprises many non-headache symptoms in itself, it also shows high comorbidity with other chronic pain and non-pain conditions (e.g., fibromyalgia syndrome, irritable bowel syndrome, functional non-epileptic seizures, depression, anxiety, and posttraumatic stress disorder). Such "symptom disorders" share several etiological factors (e.g., female preponderance, psychological vulnerability) and psychophysiological mechanisms (e.g., altered sensory processing, pain expectancy). These facts are acknowledged by several recent integrative conceptualizations such as chronic primary pain, chronic overlapping pain conditions, or functional somatic disorders. Accordingly, migraine management increasingly addresses the total symptom burden and individual contributors to symptom experience, and thus incorporates centrally acting pharmacological and non-pharmacological, that is, psychological and behavioral, treatment approaches.

CONCLUSIONS

Migraine and also other primary headache disorders should be seen as particular phenotypes within a broader spectrum of symptom perception and processing disorders that require integrative diagnostics and treatment. A harmonization of classifications and better interdisciplinary collaboration are desirable.

Digital headache self-management interventions for patients with a primary headache disorder: A systematic review of randomized controlled trials

OBJECTIVE

This article systematically reviews the empirical literature examining the efficacy of digital headache management interventions for patients with a primary headache disorder.

BACKGROUND

Digital headache management interventions provide opportunities to improve access to behavioral headache interventions to underserved groups.

METHODS

A systematic search of PubMed, Scopus, and EBSCO (PsycInfo, Education Research Complete, ERIC, Health Source: Nursing/Academic Edition, Psychology and Behavioral Sciences Collection) and reference review was conducted. Included studies had to recruit a sample with a primary headache diagnosis, be a randomized controlled trial including a digital component, assess a headache outcome (i.e., frequency, duration, severity, intensity, disability) or quality of life, and be published in English. Two authors independently extracted data for included studies. The methodological quality of studies was assessed using the revised Cochrane risk-of-bias tool.

RESULTS

Thirteen studies with unique interventions met inclusion criteria. More than half of the studies were pilots; however, nearly 70% (9/13) demonstrated significant between-group or within-group improvements on one or more headache-related outcomes. All interventions included some form of relaxation training and the majority were delivered via interactive website. While fewer than half the studies report participant race and/or ethnicity, of those that do, 83% (5/6) reported a predominately White/Caucasian sample.

CONCLUSIONS

Efficacy testing of digital headache interventions is in its infancy with the majority of these studies relying on pilot studies with small samples comprised of homogenous patient populations. Interactive websites were the most common digital medium to deliver digital headache management interventions and have demonstrated promising results. Further testing using large-scale randomized controlled trials and exploration of other digital tools is warranted. Future studies with more diverse samples are needed to inform health equity of digital headache interventions.

Lifestyle factors and migraine

Migraine, a common and disabling neurological disorder, is among the top reasons for outpatient visits to general neurologists. In addition to pharmacotherapy, lifestyle interventions are a mainstay of treatment. High-quality daily diary studies and intervention studies indicate intraindividual variations in the associations between lifestyle factors (such as stress, sleep, diet, and physical activity) and migraine attack occurrence. Behaviour change interventions can directly address overlapping lifestyle factors; combination approaches could capitalise on multiple mechanisms. These findings provide useful directions for integration of lifestyle management into routine clinical care and for future research.

Network Analysis Reveals That Headache-Related, Psychological and Psycho-Physical Outcomes Represent Different Aspects in Women with Migraine

Evidence supports that migraine is a complex pain condition with different underlying mechanisms. We aimed to quantify potential associations between demographic, migraine-related, and psychophysical and psychophysical variables in women with migraine. Demographic (age, height, and weight), migraine-related (intensity, frequency, and duration), related-disability (Migraine Disability Assessment Scale, Headache Disability Inventory), psychological (Hospital Anxiety and Depression Scale), and psycho-physical (pressure pain thresholds -PPTs-) variables were collected from a sample of 74 women suffering from migraine. We calculated adjusted correlations between the variables by using a network analysis. Additionally, we also calculated centrality indices to identify the connectivity among the variables within the network and the relevance of each variable in the network. Multiple positive correlations (ρ) between PPTs were observed ranging from 0.1654 (C5-C6 and tibialis anterior) to 0.40 (hand and temporalis muscle). The strongest associations within the network were those between migraine attack frequency and diagnosis of chronic migraine (ρ = 0.634) and between the HDI-E and HDI-P (ρ = 0.545). The node with the highest strength and betweenness centrality was PPT at the second metacarpal, whereas the node with the highest harmonic centrality was PPT at the tibialis anterior muscle. This is the first study applying a network analysis to understand the underlying mechanisms in migraine. The identified network revealed that a model where each subgroup of migraine-related, psychological, and psycho-physical variables showed no interaction between each variable. Current findings could have clinical implications for developing multimodal treatments targeting the identified mechanisms.

Psychiatric Comorbidity and Emotional Dysregulation in Chronic Tension-Type Headache: A Case-Control Study

Background: Chronic tension-type headache (CTTH) is frequently associated with a psychiatric comorbidity of depression and anxiety. Most studies focus their attention on this association, and only few link CTTH with psycho-affective emotional regulation disorders. Objective: To evaluate the association of CTTH with anxiety, depression, positive and negative affectivity, and emotional management in CTTH patients with neither a previous diagnosis of psychiatric disorder nor use of psychoactive drugs or abuse of analgesics. Design: Case-control study. Methods: Validated scores for state and trait anxiety, depression, positive and negative state and trait affect, cognitive reappraisal, and expressive suppression were assessed in 40 subjects with CTTH and 40 healthy subjects. Associations between CTTH and psychological status were assessed through linear multivariate regression models. Results: CTTH was associated with higher scores for depression (Beta = 5.46, 95% CI: 1.04–9.88), state and trait anxiety (Beta = 12.77, 95% CI: 4.99–20.56 and Beta = 8.79, 95% CI: 2.29–15.30, respectively), and negative state affect (Beta = 5.26, 95% CI: 0.88–9.64). Conclusions: CTTH is directly associated with depression, anxiety, and negative affectivity signs despite the absence of a previously diagnosed psychiatric disorder or psychopharmacological intake. The recognition of these comorbid and psycho-affective disorders is essential to adapt the emotional management of these patients for better control.

Applying a biopsychosocial model to migraine: rationale and clinical implications

Migraine is a complex condition in which genetic predisposition interacts with other biological and environmental factors determining its course. A hyperresponsive brain cortex, peripheral and central alterations in pain processing, and comorbidities play a role from an individual biological standpoint. Besides, dysfunctional psychological mechanisms, social and lifestyle factors may intervene and impact on the clinical phenotype of the disease, promote its transformation from episodic into chronic migraine and may increase migraine-related disability.Thus, given the multifactorial origin of the condition, the application of a biopsychosocial approach in the management of migraine could favor therapeutic success. While in chronic pain conditions the biopsychosocial approach is already a mainstay of treatment, in migraine the biomedical approach is still dominant. It is instead advisable to carefully consider the individual with migraine as a whole, in order to plan a tailored treatment. In this review, we first reported an analytical and critical discussion of the biological, psychological, and social factors involved in migraine. Then, we addressed the management implications of the application of a biopsychosocial model discussing how the integration between non-pharmacological management and conventional biomedical treatment may provide advantages to migraine care.

Effectiveness of dry needling for headache: A systematic review

INTRODUCTION

Non-pharmacological treatment of patients with headache, such as dry needling (DN), is associated with less morbidity and mortality and lower costs than pharmacological treatment. Some of these techniques are useful in clinical practice. The aim of this study was to review the level of evidence for DN in patients with headache.

METHODS

We performed a systematic review of randomised clinical trials on headache and DN on the PubMed, Web of Science, Scopus, and PEDro databases. Methodological quality was evaluated with the Spanish version of the PEDro scale by 2 independent reviewers.

RESULTS

Of a total of 136 studies, we selected 8 randomised clinical trials published between 1994 and 2019, including a total of 577 patients. Two studies evaluated patients with cervicogenic headache, 2 evaluated patients with tension-type headache, one study assessed patients with migraine, and the remaining 3 evaluated patients with mixed-type headache (tension-type headache/migraine). Quality ratings ranged from low (3/10) to high (7/10). The effectiveness of DN was similar to that of the other interventions. DN was associated with significant improvements in functional and sensory outcomes.

CONCLUSIONS

Dry needling should be considered for the treatment of headache, and may be applied either alone or in combination with pharmacological treatments.

Headache-related cognitive distortions questionnaire

Background. - Cognitive distortions are systematic errors in thinking and can be observed in the relationship of headache patients with their own disease and treatment. Objective. - To construct and validate an instrument to evaluate headache-related cognitive distortions in those with primary headache disorders; and to investigate the psychometric properties of this new instrument. Methods. - One hundred thirty-six (136) migraine outpatients from three Brazilian specialized headache hospital services completed the Headache-related Cognitive Distortions Inventory (HCDQ) and validated measures of psychological symptoms, pain catastrophizing, mood disorders, quality of life and headache-related disability. Results. - All hypothesized study measures’ correlations were statistically significant, supporting construct validity. HCDQ scores were positively correlated with headache frequency, headache intensity, psychological symptoms, depression, anxiety, and pain catastrophizing; and negatively correlated with 7 of 8 quality of life domains and time the patient was in treatment. Cronbach’s alpha demonstrated excellent internal consistency for the 17-item total scale (alpha=.92). Along with headache intensity and depression, HCDQ Pain subscale accounted for 46% of variance in the prediction of headache-related disability. Conclusions. - HCDQ is a valid and reliable measure of migraine patients´ cognitive distortions about their headaches and headache treatment.

Behavioral Management of Episodic Migraine: Maintaining a Healthy Consistent Lifestyle

PURPOSE OF REVIEW

To describe the most recent findings related to lifestyle behaviors and migraine.

RECENT FINDINGS

An individualized conceptualization of how lifestyle factors impact migraine activity has increased our understanding of the role of behavioral interventions for episodic migraine. Healthy diets of several types have been associated with migraine attack reduction, whereas disruptions in diet like skipping meals are associated with migraine attack onset. Both aerobic activity and lower intensity yoga interventions show promise for migraine prevention. Sleep disruption has been associated with migraine day and may have a bi-directional relationship. Both increases and decreases in stress have been associated with migraine activity. Evidence is converging around the principle that highly unusual disruptions in daily routine are particularly associated with migraine attack onset and that a consistent healthy lifestyle is a key feature of effective behavioral migraine prevention strategies.

Neuropsychiatric Treatment for Mild Traumatic Brain Injury: Nonpharmacological Approaches

Postconcussive symptoms following mild traumatic brain injury (mTBI)/concussion are common, disabling, and challenging to manage. Patients can experience a range of symptoms (e.g., mood disturbance, headaches, insomnia, vestibular symptoms, and cognitive dysfunction), and neuropsychiatric management relies heavily on nonpharmacological and multidisciplinary approaches. This article presents an overview of current nonpharmacological strategies for postconcussive symptoms including psychoeducation; psychotherapy; vestibular, visual, and physical therapies; cognitive rehabilitation; as well as more novel approaches, such as neuromodulation. Ultimately, treatment and management of mTBI should begin early with appropriate psychoeducation/counseling, and be tailored based on core symptoms and individual goals.

A Brief Survey of the COVID-19 Pandemic's Impact on the Chronic Pain Experience

BACKGROUND

The COVID-19 pandemic has forced sweeping social and behavioral changes that have adversely affected the general population. Many changes, such as business closures, working from home, increased psychological distress, and delayed access to health care, could have unique adverse effects on patients diagnosed with chronic pain (CP). The present study sought to examine perceived changes in the CP experience brought about by the COVID-19 pandemic.

DESIGN

Participants included 487 self-reported patients with musculoskeletal, neuropathic, or postsurgical pain recruited using CloudResearch. A 53-item survey was created to assess changes in perceived pain, mood, control over pain, physical activity, employment, and medical access since the onset of the pandemic.

RESULTS

Results suggested a worsening of the pain experience, particularly for women, with greater pain, negative affect, sedentary functioning, perceived decline in treatment quality, and increased treatment delays. Of note, pandemic-related declines in control over pain, which represents an important clinical target, are associated with other pandemic-related declines and also mediates relevant associations.

CONCLUSIONS

For frontline treatment providers, particularly primary care nurses and physicians, these findings may be relevant in order to reduce the likelihood of a worsening of symptoms, loss of self-efficacy regarding management of pain and/or potential maladaptive increase in the use of pain medications.

Behavioural intervention in medication overuse headache: a concealed double‐blind randomised controlled trial a concealed double‐blind randomised controlled trial a concealed double‐blind randomised controlled trial

Background and purpose

Medication overuse headache is a prevalent disorder, with a strong biobehavioural component. Hence, behavioural interventions might effectuate reduction of the overused medication. We assessed in a double‐blind manner the efficacy of a behavioural intervention during medication withdrawal therapy.

Methods

In this concealed, double‐blind, randomized controlled trial in medication overuse headache, conducted at the Leiden University Medical Centre, we compared the effect of maximal versus minimal behavioural intervention by a headache nurse during withdrawal therapy. Maximal intervention consisted of an intensive contact schedule, comprising education, motivational interviewing, and value‐based activity planning during 12 weeks of withdrawal therapy. Minimal intervention consisted of a short contact only. Patients were unaware of the existence of these treatment arms, as the trial was concealed in another trial investigating botulinum toxin A. Endpoints were successful withdrawal and monthly days of acute medication use after the withdrawal period.

Results

We enrolled 179 patients (90 maximal, 89 minimal intervention). At Week 12, most patients achieved withdrawal in both groups (82/90 [93%] maximal intervention vs. 75/89 [86%] minimal intervention, odds ratio = 2.44, 95% confidence interval [CI] = 0.83–7.23, p = 0.107). At Week 24, patients in the maximal intervention group had fewer medication days (mean difference = −2.23, 95% CI = −3.76 to −0.70, p = 0.005). This difference receded over time. Change in monthly migraine days did not differ between groups (−6.75 vs. −6.22).

Conclusions

This trial suggests modest benefit of behavioural intervention by a headache nurse during withdrawal therapy for medication overuse headache, to reduce acute medication use during and shortly after intervention, but extension seems warranted for a prolonged effect

The Primary Care Management of Headache: Synopsis of the 2020 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guideline

INTRODUCTION

In June of 2020, the U.S. DVA and DoD approved a new joint clinical practice guideline for assessing and managing patients with headache. This guideline provides a framework to evaluate, treat, and longitudinally manage the individual needs and preferences of patients with headache.

METHODS

In October of 2018, the DVA/DoD Evidence-Based Practice Work Group convened a guideline development panel that included clinical stakeholders and conformed to the National Academy of Medicine's tenets for trustworthy clinical practice guidelines.

RESULTS

The guideline panel developed key questions, systematically searched and evaluated the literature, created a 1-page algorithm, and advanced 42 recommendations using the Grading of Recommendations Assessment, Development, and Evaluation system.

CONCLUSION

This synopsis summarizes the key features of the guideline in three areas: prevention, assessing and treating medication overuse headache, and nonpharmacologic and pharmacologic management of headache.

Behavioral Health, Telemedicine, and Opportunities for Improving Access

PURPOSE OF REVIEW

The purpose of this review is to summarize advances in behavioral treatments for pain and headache disorders, as well as recent innovations in telemedicine for behavioral treatments.

RECENT FINDINGS

Research for behavioral treatments continues to support their use as part of a multidisciplinary approach to comprehensive management for pain and headache conditions. Behavioral treatments incorporate both behavioral change and cognitive interventions and have been shown to improve outcomes beyond that of medical management alone. The onset of the COVID-19 public health emergency necessitated the rapid uptake of nontraditional modalities for behavioral treatments, particularly telemedicine. Telemedicine has long been considered the answer to several barriers to accessing behavioral treatments, and as a result of COVID-19 significant progress has been made evaluating a variety of telemedicine modalities including synchronous, asynchronous, and mobile health applications. Researchers are encouraged to continue investigating how best to leverage these modalities to improve access to behavioral treatments and to continue evaluating the efficacy of telemedicine compared to traditional in-person care. Comprehensive pain and headache management should include behavioral treatments to address a variety of behavior change and cognitive targets. Policy changes and advances in telemedicine for behavioral treatments provide the opportunity to address historical barriers limiting access.

Relation of hypertension with episodic primary headaches and chronic primary headaches in population of Rafsanjan cohort study

Headache has a variety of types, such as episodic primary headaches (EPH) and chronic primary headache (CPH) in its primary form. There is a positive correlation between these two types of headaches and hypertension (HTN), but in some works this correlation has been reported negatively. Therefore, we planned to study HTN-CPH as well as HTN-EPH correlation in our population. A sample of Rafsanjan population (10,000 individuals) entered the cohort study, as one of the Prospective Epidemiological Research Studies in Iran (PERSIAN). We compared the frequency of HTN categories in CPH and EPH cases with a normal population. Out of 9933 participants (46.6% males and 53.4% females) about 29% had EPH and 7.5% had CPH. HTN was found in 24.27% of EPH cases and 31.98% of CPH cases. HTN was also found to be associated with EPH and CPH in the crude model. Two Categories of HTN (Long controlled and uncontrolled) were not associated with EPH. On the other hand, CPH showed associations with all of the HTN categories. After included all variables and confounders, EPH and CPH had association with HTN without any considerable changes. There is strong HTN-EPH as well as HTN-CPH correlations in the studied population.

Treatment of chronic migraine and neck pain with cognitive-behavioral therapy. Case report

The article presents a case of a patient with chronic migraine, neck pain, drug-induced headache and generalized anxiety disorder. We analyzed the relationship between migraines and neck pain. The article discusses the interdisciplinary treatment of chronic migraine, which included educational conversation, detoxification therapy, rational relief of migraine attacks, preventive pharmacotherapy and cognitive-behavioral therapy. The latter allowed to change the patient's perception of the disease, reduce anxiety and catastrophization of pain, cope with fears, stop taking benzodiazepines, reduce the intake of pain relievers, and increase daily activity and productivity at work. Clinical efficacy (reduction in the frequency of headaches per month by 50% or more) was achieved after 3 months of treatment. Long-term (12 months) follow-up of the patient showed long-term clinical effect of the interdisciplinary treatment.

Effect of a Mindfulness-Based Intervention for Chronic Migraine and High Frequency Episodic Migraine in Adolescents: A Pilot Single-Arm Open-Label Study

In this single-arm pilot open-label study we examined the effect of a mindfulness-based intervention on reduction of headache frequency after 12 months in adolescents aged 12-18 with chronic or high-frequency migraine without aura. Adolescents were recruited at the headache center of the C. Besta Neurological Institute and followed-up for 12 months. The mindfulness-based intervention was delivered in small groups and consisted of six weekly group sessions of guided meditation, and one booster session 15 days after. Patients filled in questionnaires assessing headache frequency (primary endpoint), medication intake, disability, anxiety, depression, catastrophizing, and caregivers' burden. Within-person ANOVA was used to address variation of endpoints over time. Thirty-five out of 37 patients completed the study for primary endpoints, and 33 for secondary endpoints. Headache frequency dropped from 21.3 (95% CI 18.5; 24.1) to 9.6 (95% CI 6.1; 13.1) days per month at 12 months (F = 30.5, p < 0.001); 23 patients out of 35 (65.7%) achieved a headache frequency reduction greater than or equal to 50%. Significant improvements were also reported for medication intake (F = 18.7, p < 0.001), disability (F = 3.8, p = 0.027), trait anxiety (F = 5.1, p = 0.009), symptoms of depression (F = 9.5, p < 0.001), and catastrophizing (F = 23.6, p < 0.001). In conclusions, our study shows a reduction of headache attacks in adolescents who follow a mindfulness-based program, suggesting benefit of this nonpharmacological approach.

The Use of Behavioral Modalities for Headache During Pregnancy and Breastfeeding

Purpose of Review

Migraine is primary headache which commonly affects women of childbearing age. Migraine and other primary headache disorders are also common during pregnancy. Understanding which treatments are effective and can be safely given to patients with primary headache during pregnancy and lactation is essential in supporting these patients before, during, and after childbirth. Behavioral modalities have the potential to improve the health of both mother and baby, while empowering patients to make informed decisions in family planning and creating future treatment plans.

Recent Findings

Research shows that behavioral therapies can be powerful tools to treat pain conditions with minimal side effects. Recent literature prioritizes behavioral therapies in preparation for pregnancy, during pregnancy, and during lactation due to the superior safety profile of such therapies. Digital resources for behavioral therapy are another well-received recent direction supported by growing evidence of both efficacy and safety. Popular with patients and headache specialists, digital behavioral therapy has taken various forms during the pandemic, such as telemedicine, online psychology support groups, and smartphone applications that patients can interact with on their own time.

Summary

In summary, the purpose of this review is to equip providers with important information and updates on the use of behavioral modalities for the treatment of primary headache during pregnancy and lactation.

Sufficient conditions for effective psychological treatment of chronic pain: a qualitative comparative analysis

ABSTRACT

Chronic pain (CP) is the leading cause of years lived with disability globally. Treatment within Western medicine is often multicomponent; the psychological element of treatment varies, yet the optimal conditions for effective reduction of pain-related outcomes remain unclear. This study used qualitative comparative analysis, a relatively new form of evidence synthesis in the field based on set theory to ascertain configurations of intervention components and processes of psychological treatment of chronic pain in adults that lead to more effective interventions. Data were extracted from 38 studies identified in a concurrent Cochrane review and were then subjected to qualitative comparative analysis. Two analyses were conducted: one to examine what is most effective for reducing disability and one to examine what is most effective for reducing distress. Analysis and comparison of the 10 treatments with best outcomes with the 10 treatments with poorest outcomes showed that interventions using graded exposure, graded exercise or behavioural rehearsal (exposure/activity), and interventions aiming to modify reinforcement contingencies (social/operant) reduced disability levels when either approach was applied but not both. Exposure/activity can improve distress levels when combined with cognitive restructuring, as long as social/operant methods are not included in treatment. Clinical implications of this study suggest that treatment components should not be assumed to be synergistic and provided in a single package.

Headache in people with epilepsy

Epidemiological estimates indicate that individuals with epilepsy are more likely to experience headaches, including migraine, than individuals without epilepsy. Headaches can be temporally unrelated to seizures, or can occur before, during or after an episode; seizures and migraine attacks are mostly not temporally linked. The pathophysiological links between headaches (including migraine) and epilepsy are complex and have not yet been fully elucidated. Correct diagnoses and appropriate treatment of headaches in individuals with epilepsy is essential, as headaches can contribute substantially to disease burden. Here, we review the insights that have been made into the associations between headache and epilepsy over the past 5 years, including information on the pathophysiological mechanisms and genetic variants that link the two disorders. We also discuss the current best practice for the management of headaches co-occurring with epilepsy and highlight future challenges for this area of research.

Manual joint mobilisation techniques, supervised physical activity, psychological treatment, acupuncture and patient education for patients with tension-type headache. A systematic review and meta-analysis

Background

Tension-type headache (TTH) has been ranked the second most prevalent health condition worldwide. Non-pharmacological treatments for TTH are widely used as a supplement or an alternative to medical treatment. However, the evidence for their effects are limited. Therefore, the aim of this study was to review the evidence for manual joint mobilisation techniques, supervised physical activity, psychological treatment, acupuncture and patient education as treatments for TTH on the effect of headache frequency and quality of life.

Methods

A systematic literature search was conducted from February to July 2020 for clinical guidelines, systematic reviews, and individual randomised controlled trials (RCT). The primary outcomes measured were days with headache and quality of life at the end of treatment along with a number of secondary outcomes. Meta-analyses were performed on eligible RCTs and pooled estimates of effects were calculated using the random-effect model. The overall certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation approach (GRADE). In addition, patient preferences were included in the evaluation.

Results

In all, 13 RCTs were included. Acupuncture might have positive effects on both primary outcomes. Supervised physical activity might have a positive effect on pain intensity at the end of treatment and headache frequency at follow-up. Manual joint mobilisation techniques might have a positive effect on headache frequency and quality of life at follow-up. Psychological treatment might have a positive effect on stress symptoms at the end of treatment. No relevant RCTs were identified for patient education. The overall certainty of evidence was downgraded to low and very low. No serious adverse events were reported. A consensus recommendation was made for patient education and weak recommendations for the other interventions.

Conclusion

Based on identified benefits, certainty of evidence, and patient preferences, manual joint mobilisation techniques, supervised physical activity, psychological treatment, acupuncture, and patient education can be considered as non-pharmacological treatment approaches for TTH. Some positive effects were shown on headache frequency, quality of life, pain intensity and stress symptoms. Few studies and low sample sizes posed a challenge in drawing solid conclusions. Therefore, high-quality RCTs are warranted.

Revised guidelines of the French headache society for the diagnosis and management of migraine in adults. Part 3: Non-pharmacological treatment

The French Headache Society proposes updated French guidelines for the management of migraine. This article presents the third part of the guidelines, which is focused on the non-pharmacological treatment of migraine, including physical exercise, dietary supplements and plants, diets, neuromodulation therapies, acupuncture, behavioral interventions and mindfulness therapy, patent foramen ovale closure and surgical nerve decompression.

What is the link between migraine and psychiatric disorders? From epidemiology to therapeutics

The association between migraine and psychiatric disorders is well documented through numerous population-based studies. The results of these studies are coherent and show an increased risk of suffering from depression, bipolar disorders, numerous anxiety disorders, especially post-traumatic stress disorder. This raises the question of stress as a precipitating factor for migraine illness. Psychiatric comorbidity is even more frequent in chronic migraine than in episodic migraine patients. Many prospective studies have shown that psychiatric comorbidity could be considered as a risk factor for migraine chronicization. Psychiatric comorbidity is also responsible for an increase of the frequency of anti-migraine drug intake, a worsening of quality of life and a worsening of functional impairment. It is also responsible for an increase in the direct and indirect costs of migraine. The reason why psychiatric comorbidity is so high in migraineurs is not unambiguous. Multiple causal relationships and common etiological factors are linked. Recently, genome-wide association studies gave leads to a genetic common heritability between major depressive disorder and migraine. For clinicians, an important topic remains how to treat migraineurs with psychiatric comorbidity. These patients suffer frequently from severe migraine or refractory migraine. Antidepressant and anti-convulsive drugs can be useful, as well as psychological therapies. But moreover, it is of utmost importance to propose an integrated multidisciplinary approach to these difficult patients.

Comorbidities of primary headache disorders: a literature review with meta-analysis

Background

Primary headache disorders are common and burdensome conditions. They are associated to several comorbidities, such as cardiovascular or psychiatric ones, which, in turn, contribute to the global burden of headache. The aim of this study is to provide a comprehensive description of the pooled prevalence of comorbidities of primary headache disorders using a meta-analytical approach based on studies published between 2000 and 2020.

Methods

Scopus was searched for primary research (clinical and population studies) in which medical comorbidities were described in adults with primary headache disorders. Comorbidities were extracted using a taxonomy derived from the Global Burden of Disease (GBD) study. We compared prevalence of comorbidities among headache sufferers against general population using GBD-2019 estimates, and compared comorbidities’ proportions in clinical vs. population studies, and by age and gender.

Results

A total of 139 studies reporting information on 4.19 million subjects with primary headaches were included: in total 2.75 million comorbidities were reported (median per subject 0.64, interquartile range 0.32–1.07). The most frequently addressed comorbidities were: depressive disorders, addressed in 51 studies (pooled proportion 23 %, 95 % CI 20–26 %); hypertension, addressed in 48 studies (pooled proportion 24 %, 95 % CI 22–26 %); anxiety disorders addressed in 40 studies (pooled proportion 25 %, 95 % CI 22–28 %). For conditions such as anxiety, depression and back pain, prevalence among headache sufferers was higher than in GBD-2109 estimates. Associations with average age and female prevalence within studies showed that hypertension was more frequent in studies with higher age and less females, whereas fibromyalgia, restless leg syndrome, and depressive disorders were more frequent in studies with younger age and more female.

Conclusions

Some of the most relevant comorbidities of primary headache disorders – back pain, anxiety and depression, diabetes, ischemic heart disease and stroke – are among the most burdensome conditions, together with headache themselves, according to the GBD study. A joint treatment of headaches and of these comorbidities may positively impact on headache sufferers’ health status and contribute to reduce the impact of a group of highly burdensome diseases.

Telerehabilitation for Headache Management

Headache is one of the most disabling conditions in the world. Despite plentiful evidence supporting rehabilitation strategies, headache is significantly underassessed and undertreated. Obstacles to headache care include lack of available expertise in headache management, few available resources for effective assessment and treatment, and cost and disability that preclude treatment seeking in patients with headache. Telerehabilitation can allow providers to access expert consultation and gives patients easier access to assessment and treatment. This article covers existing telerehabilitation options for headache management and explores the strength of evidence supporting these approaches. Risks of telerehabilitation and recommendations for future development are discussed.

Non-Pharmacological Approaches to Headaches: Non-Invasive Neuromodulation, Nutraceuticals, and Behavioral Approaches

Significant side effects or drug interactions can make pharmacological management of headache disorders very difficult. Non-conventional and non-pharmacological treatments are becoming increasingly used to overcome these issues. In particular, non-invasive neuromodulation, nutraceuticals, and behavioral approaches are well tolerated and indicated for specific patient categories such as adolescents and pregnant women. This paper aims to present the main approaches reported in the literature in the management of headache disorders. We therefore reviewed the available literature published between 2010 and 2020 and performed a narrative presentation for each of the three categories (non-invasive neuromodulation, nutraceuticals, and behavioral therapies). Regarding non-invasive neuromodulation, we selected transcranial magnetic stimulation, supraorbital nerve stimulation, transcranial direct current stimulation, non-invasive vagal nerve stimulation, and caloric vestibular stimulation. For nutraceuticals, we selected Feverfew, Butterbur, Riboflavin, Magnesium, and Coenzyme Q10. Finally, for behavioral approaches, we selected biofeedback, cognitive behavioral therapy, relaxation techniques, mindfulness-based therapy, and acceptance and commitment therapy. These approaches are increasingly seen as a valid treatment option in headache management, especially for patients with medication overuse or contraindications to drug treatment. However, further investigations are needed to consider the effectiveness of these approaches also with respect to the long-term effects.

Identification of neural and psychophysical predictors of headache reduction after cognitive behavioral therapy in adolescents with migraine

ABSTRACT

Cognitive behavioral therapy (CBT) is a psychological intervention that involves development of coping strategies to reduce the experience of pain. Although CBT is a promising intervention to reduce headache days in patients with migraine, it may not be effective for all patients. Thus, there is a need to identify markers that could predict which patients will respond to CBT. We aimed to determine whether baseline brain function and amygdalar connectivity, assessed by functional magnetic resonance imaging, or pain modulation capacities, assessed by the conditioned pain modulation (CPM) response, can predict a reduction in headache days after CBT in adolescents with migraine. Patients with migraine (n = 20; age range 10-17 years) completed 8 weekly CBT sessions. The CPM response was examined in the trapezius and the leg. Headache days significantly decreased after CBT (P < 0.001). Greater functional connectivity before CBT between the right amygdala and frontal gyrus, anterior cingulate cortex, and precentral gyrus was related to greater headache reduction after CBT. Greater reduction in headache days after CBT was related with less efficient CPM response before CBT at the trapezius (r = -0.492, P = 0.028) but not at the leg. This study found that headache reduction after CBT was related to right amygdala connectivity with frontal and sensorimotor regions at baseline as well as baseline pain modulation capacities. These findings suggest that individual differences in brain function and pain modulation can be associated with clinical improvements and help with determination of CBT responsiveness.

Headache and musculoskeletal pain in school children are associated with uncorrected vision problems and need for glasses: a case-control study

Musculoskeletal pain and headache are leading causes of years lived with disability, and an escalating problem in school children. Children spend increasingly more time reading and using digital screens, and increased near tasks intensify the workload on the precise coordination of the visual and head-stabilizing systems. Even minor vision problems can provoke headache and neck- and shoulder (pericranial) pain. This study investigated the association between headaches, pericranial tenderness, vision problems, and the need for glasses in children. An eye and physical examination was performed in twenty 10–15 year old children presenting to the school health nurse with headache and pericranial pain (pain group), and twenty age-and-gender matched classmates (control group). The results showed that twice as many children in the pain group had uncorrected vision and needed glasses. Most children were hyperopic, and glasses were recommended mainly for near work. Headache and pericranial tenderness were significantly correlated to reduced binocular vision, reduced distance vision, and the need for new glasses. That uncorrected vision problems are related to upper body musculoskeletal symptoms and headache, indicate that all children with these symptoms should have a full eye examination to promote health and academic performance.

Behavioral Medicine Methods in Treatment of Somatic Conditions

Background

The aim of this article is to present a short review of noninvasive, nonpharmacological treatment methods used in somatic illnesses that fall under the umbrella of approach called behavioral medicine.

Methods

The narrative review method was applied in the study. Science paper databases, including PubMed, had been used to retrieve papers on therapeutic methods used in clinical setting that meet the broad criteria of behavioral medicine definition as stated in the Charter of International Behavioral Medicine Society

Results

Main groups of methods, disorders in which they are being employed and their effectiveness, have been identified.

Conclusions

Behavioral medicine is grouping treatment methods and interventions that hold large potential for clinical setting. Two groups of methods can be distinguished by the scrutiny and level of evidence gathered in their effectiveness assessment; for biofeedback, guided imagery, and hypnosis techniques, comprehensive evidence reports in the framework of U.S. Evidence Synthesis Program exist. Meditation techniques, disclosure therapies, and relaxation methods are less well assessed. Broader employment of behavioral medicine therapies in clinical setting is possible after addressing two major problems in the field, which are deficiencies in quality evidence of effectiveness for many of the methods and their insufficiencies in underlying therapeutic mechanism knowledge.

Diagnosis and treatment of migraine: Russian experts' recommendations

Migraine is one of the most common types of headache, which can lead to a significant decrease in quality of life. Researchers identify migraine with aura, migraine without aura, and chronic migraine that substantially reduces the ability of patients to work and is frequently concurrent with mental disorders and drug-induced headache. The complications of migraine include status migrainosus, persistent aura without infarction, migrainous infarction (stroke), and a migraine aura-induced seizure. The diagnosis of migraine is based on complaints, past medical history, objective examination data, and the diagnostic criteria as laid down in the International Classification of Headache Disorders, 3 rd edition. Add-on trials are recommended only in the presence of red flags, such as the symptoms warning about the secondary nature of headache. Migraine treatment is aimed at reducing the frequency and intensity of attacks and the amount of analgesics taken. It includes three main approaches: behavioral therapy, seizure relief therapy, and preventive therapy. Behavioral therapy focuses on lifestyle modification. Nonsteroidal anti-inflammatory drugs, simple and combined analgesics, triptans, and antiemetic drugs for severe nausea or vomiting are recommended for seizure relief. Preventive therapy which includes antidepressants, anticonvulsants, beta-blockers, angiotensin II receptor antagonists, botulinum toxin type A-hemagglutinin complex and monoclonal antibodies to calcitonin gene-related peptide or its receptors, is indicated for frequent or severe migraine attacks and for chronic migraine. Pharmacotherapy is recommended to be combined with non-drug methods that involves cognitive behavioral therapy; progressive muscle relaxation; mindfulness; biofeedback; post-isometric relaxation; acupuncture; therapeutic exercises; greater occipital nerve block; non-invasive high-frequency repetitive transcranial magnetic stimulation; external stimulation of first trigeminal branch; and electrical stimulation of the occipital nerves (neurostimulation).

Pharmacological options for the treatment of chronic migraine pain

Migraine is a debilitating neurological condition with symptoms typically consisting of unilateral and pulsating headache, sensitivity to sensory stimuli, nausea, and vomiting. The World Health Organization (WHO) reports that migraine is the third most prevalent medical disorder and second most disabling neurological condition in the world. There are several options for preventive migraine treatments that include, but are not limited to, anticonvulsants, antidepressants, beta blockers, calcium channel blockers, botulinum toxins, NSAIDs, riboflavin, and magnesium. Patients may also benefit from adjunct nonpharmacological options in the comprehensive prevention of migraines, such as cognitive behavior therapy, relaxation therapies, biofeedback, lifestyle guidance, and education. Preventative therapies are an essential component of the overall approach to the pharmacological treatment of migraine. Comparative studies of newer therapies are needed to help patients receive the best treatment option for chronic migraine pain.

Clinical Reasoning Behind Non-Pharmacological Interventions for the Management of Headaches: A Narrative Literature Review

Headache is the clinical syndrome most commonly observed by neurologists in daily practice. Pharmacological and non-pharmacological treatments are commonly used for the management of headaches; however, the clinical reasoning behind these interventions is not properly applied. We conducted a narrative literature review using as data sources for academic PubMed, MEDLINE, EMBASE, AMED, CINAHL, EBSCO, PEDro, Cochrane Database of Systematic Reviews, Cochrane Collaboration Trials Register, and SCOPUS. This narrative literature review mainly considered systematic reviews, meta-analyses, randomised clinical trials, and expert opinions published after the year 2000 discussing clinical reasoning for application of non-pharmacological interventions in individuals with tension-type, migraine, and cervicogenic headaches. After the data extraction, we organized the literature thematically as follows: (1) mapping of theoretical aspects of non-pharmacological interventions; (2) summarizing most updated literature about effectiveness of non-pharmacological interventions grouped by targeted tissue and headache; (3) identifying research gaps in the existing literature and proposing hypotheses for better understanding of current clinical reasoning. We found that there are many non-pharmacological treatment strategies used for headaches, including beyond the tissue-based impairment treatments (bottom-up) and strategies targeting the central nervous system (top down). Bottom-up strategies include joint-biased, soft-tissue biased, or needling interventions, whereas top-down strategies include exercise and cognitive interventions. Evidence shows that the effectiveness of these interventions depends on the application of proper clinical reasoning, since not all strategies are effective for all headaches. For instance, evidence of non-pharmacological interventions is more controversial for migraines than for tension-type or cervicogenic headaches, since migraine pathogenesis involves activation of sub-cortical structures and the trigemino- vascular system, whereas pathogenesis of tension-type or cervicogenic headaches is most associated to musculoskeletal impairments of the cervical spine. We conclude that current literature suggests that not all non-pharmacological interventions are effective for all headaches, and that multimodal, not isolated, approaches seem to be more effective for patients with headaches. Most published studies have reported small clinical effects in the short term. This narrative literature review provides some hypotheses for discrepancies in the available literature and future research. Clinical reasoning should be applied to better understand the effects of non-pharmacological interventions.

Current perspectives on sex differences in tension-type headache

INTRODUCTION

Clinical and experimental evidence supports the presence of several gender differences in the pain experience.

AREAS COVERED

The current paper discusses biological, psychological, emotional, and social differences according to gender and their relevance to TTH. Gender differences have also been observed in men and women with tension-type headache and they should be considered by clinicians managing this condition. It appears that multimodal treatment approaches lead to better outcomes in people with tension-type headache; however, management of tension-type headache should consider these potential gender differences. Different studies have observed the presence of complex interactions between tension-type headache, emotional stress, sleep, and burden and that these interactions are different between men and women.

EXPERT OPINION

Based on current results, the authors hypothesize that treatment of men with tension-type headache should focus on the improvement of sleep quality and the level of depression whereas treatment of women with TTH should focus on nociceptive mechanisms and emotional/stressful factors. Future trials should investigate the proposed hypotheses.

Mindfulness in migraine: A narrative review

Introduction: Migraine is the second leading cause of disability worldwide, yet many patients are unable to tolerate, benefit from, or afford pharmacological treatment options. Non-pharmacological migraine therapies exist, especially to reduce opioid use, which represents a significant unmet need. Mindfulness-based interventions (MBI) have potential as a non-pharmacological treatment for migraine, primarily through the development of flexible attentional capacity across sensory, cognitive, and emotional experiences.Areas covered: The authors review efficacy and potential mechanisms of MBIs for migraine, including mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT).Expert opinion: While most mindfulness research studies for migraine to date have been pilot trials, which are small and/or lacked rigor, initial evidence suggests there may be improvements in overall headache-related disability and psychological well-being. Many research questions remain to help target the treatment to patients most likely to benefit, including the ideal dosage, duration, delivery method, responder characteristics, and potential mechanisms and biomarkers. A realistic understanding of these factors is important for patients, providers, and the media. Mindfulness will not 'cure' migraine; however, mindfulness may be an important tool as part of a comprehensive treatment approach to help patients 'mindfully' engage in valued life activities.

Effectiveness of dry needling for headache: A systematic review

INTRODUCTION

Non-pharmacological treatment of patients with headache, such as dry needling (DN), is associated with less morbidity and mortality and lower costs than pharmacological treatment. Some of these techniques are useful in clinical practice. The aim of this study was to review the level of evidence for DN in patients with headache.

METHODS

We performed a systematic review of randomised clinical trials on headache and DN on the PubMed, Web of Science, Scopus, and PEDro databases. Methodological quality was evaluated with the Spanish version of the PEDro scale by 2 independent reviewers.

RESULTS

Of a total of 136 studies, we selected 8 randomised clinical trials published between 1994 and 2019, including a total of 577 patients. Two studies evaluated patients with cervicogenic headache, 2 evaluated patients with tension-type headache, one study assessed patients with migraine, and the remaining 3 evaluated patients with mixed-type headache (tension-type headache/migraine). Quality ratings ranged from low (3/10) to high (7/10). The effectiveness of DN was similar to that of the other interventions. DN was associated with significant improvements in functional and sensory outcomes.

CONCLUSIONS

Dry needling should be considered for the treatment of headache, and may be applied either alone or in combination with pharmacological treatments.

Consensus of the Hellenic Headache Society on the diagnosis and treatment of migraine

More than 0.6 million people suffer from disabling migraines in Greece causing a dramatic work loss, but only a small proportion of migraineurs attend headache centres, most of them being treated by non-experts. On behalf of the Hellenic Headache Society, we report here a consensus on the diagnosis and treatment of adult migraine that is based on the recent guidelines of the European Headache Federation, on the principles of Good Clinical Practice and on the Greek regulatory affairs. The purposes are three-fold: (1) to increase awareness for migraine in Greece; (2) to support Greek practitioners who are treating migraineurs; and (3) to help Greek migraineurs to get the most appropriate treatment. For mild migraine, symptomatic treatment with high dose simple analgesics is suggested, while for moderate to severe migraines triptans or non-steroidal anti-inflammatory drugs, or both, should be administered following an individually tailored therapeutic strategy. A rescue acute treatment option should always be advised. For episodic migraine prevention, metoprolol (50–200 mg/d), propranolol (40–240 mg/d), flunarizine (5–10 mg/d), valproate (500–1800 mg/d), topiramate (25–100 mg/d) and candesartan (16–32 mg/d) are the drugs of first choice. For chronic migraine prevention topiramate (100-200 mg/d), valproate (500–1800 mg/d), flunarizine (5–10 mg/d) and venlafaxine (150 mg/d) may be used, but the evidence is very limited. Botulinum toxin type A and monoclonal antibodies targeting the CGRP pathway (anti-CGRP mAbs) are recommended for patients suffering from chronic migraine (with or without medication overuse) who failed or did not tolerate two previous treatments. Anti-CGRP mAbs are also suggested for patients suffering from high frequency episodic migraine (≥8 migraine days per month and less than 14) who failed or did not tolerate two previous treatments.
