Emotional problems and prevalence of medication overuse in pediatric chronic daily headache

Medication overuse headache

Medication overuse headache (MOH) is a secondary headache disorder attributed to overuse of acute headache medications by a person with an underlying headache disorder, usually migraine or tension-type headache. MOH is common among individuals with 15 or more headache days per month. Although MOH is associated with substantial disability and reductions in quality of life, this condition is often under-recognized. As MOH is both preventable and treatable, it warrants greater attention and awareness. The diagnosis of MOH is based on the history and an unremarkable neurological examination, and is made according to the diagnostic criteria of the International Classification of Headache Disorders third edition (ICHD-3). Pathophysiological mechanisms of MOH include altered descending pain modulation, central sensitization and biobehavioural factors. Treatment of MOH includes the use of headache preventive therapies, but essential to success is eliminating the cause, by reducing the frequency of use of acute headache medication, and perhaps withdrawing the overused medication altogether. Appropriate treatment is usually highly effective, leading to reduced headache burden and acute medication consumption.

Outcomes That Matter to Adolescents With Continuous Headache Due to Chronic Migraine and Their Parents: A Pilot Survey Study

BACKGROUND

Children and adolescents with chronic migraine who have continuous headache may have high levels of headache-related disability but have largely been excluded from clinical trials. Understanding patient-valued treatment outcomes may facilitate future study design.

OBJECTIVE

To identify patient-valued outcome measures for headache preventive treatments among adolescents with continuous headache due to chronic migraine and their parents.

METHODS

Adolescents with an ICHD-3 diagnosis of chronic migraine, who had continuous headache and who were being cared for at a tertiary pediatric headache clinic, and their parents, were surveyed to query the value of treatment outcomes in the domains of headache frequency, intensity, functional impact, and associated symptoms. Individual outcomes and categories of outcomes were ranked in order of preference using weighted average rank. Results were rounded to the degree of precision with which they were measured.

RESULTS

The survey was completed by 55 adolescents and 60 parents of adolescents with continuous headache due to chronic migraine. Mean age of adolescents was 16 (SD 1, range 12 to 17). Median adolescent-reported duration of continuous headache was 24 months (IQR 12-39) and adolescents had tried a median (IQR) of 2 (0-5) preventive medications, only 13% of which were perceived as helpful. Overall, the most valued individual outcome measure among both adolescents and parents was a decrease in frequency of more severe headaches; however, outcomes reflecting headache intensity were most valued by adolescents while outcomes reflecting functional impact were most valued by parents. Over 60% of adolescents felt that it was more important to measure decrease in frequency and intensity of headaches in terms of severe headaches/spikes rather than total headache days. Among associated symptoms, improvement in "brain fog" was most highly valued by both adolescents and parents.

DISCUSSION

The results of this study provide important information about which preventive treatment outcomes are valued by adolescents with continuous headache due to chronic migraine and their parents. Results suggest that adolescents value a decrease in frequency of severe headaches over a decrease in frequency of headache days overall. Generalizability may be limited as the surveyed population were being cared for at a tertiary pediatric headache clinic and generally had headache disorders that were refractory to treatment. These results may help guide future trial design in this population with continuous headache due to chronic migraine.

Pediatric Medication-overuse Headache and Global Headache Research. A Systematic Review

Medication-overuse headache (MOH) is a relevant topic of interest but pediatric studies are scarce. Some authors have expressed their opinion regarding geographical differences in the perceived importance of adult MOH between European and North American research. To determine if there is a geographic difference in the research efforts on pediatric MOH; and to study pediatric MOH prevalence of published studies. An analysis of the Global Burden of Disease database focusing on Headache disorders prevalence per region was correlated with the region where research was conducted via PubMed search on pediatric MOH from 2006-2021. Analysis of databases from PubMed, HINARI, and ScienceDirect found 13 studies that fulfilled inclusion criteria to evaluate pediatric MOH prevalence. 6 regions were analyzed North America, Latin America, Europe, Asia, Africa, Oceania. Regions with higher prevalence of headache disorders were North America (28.45%) and Europe (28.54%).  Most pediatric MOH publications were from North America (44.2%) and Europe (37.2%). The prevalence found of pediatric MOH among pediatric headache patients is 4-11%. Prevalence increases to 20-70% among patients having a diagnosis of chronic headache. Higher prevalence was found in patients suffering post traumatic headaches. The perceived importance for pediatric MOH is similar between North America and Europe based on the research published. The prevalence varies greatly between published studies. Relationship between Post-traumatic headache and pediatric MOH prevalence should be further studied.

Pediatric Chronic Migraine Severity and Maternal Stress

Primary headache is an increasing phenomenon in pediatric age, and very often, it causes disabling limitations in children's daily activities, negatively affecting family well-being. There are conflicting data in the literature on the impact of children's migraines on parental experienced stress. This study aimed to evaluate maternal stress in a sample of school-aged children with a migraine without aura (MwoA) and its correlation with migraine intensity and frequency. A total of 474 mothers aged between 31 and 55 participated in the study: 237 were mothers of children with MwoA, and 237 were mothers of typical developing children. All participants were administered the Parent Stress Index-Short Form (PSI-SF) for the assessment of parental stress; the Pediatric Migraine Disability Assessment (PedMIDAS) was administered to children with MwoA to assess the presence of a related disability migraine. The results showed a significantly higher rate of stress in mothers of MwoA children (p < 0.001) in all the domains explored by the PSI-SF and a statistically significant correlation between the maternal stress total score and the intensity and frequency of migraine attacks (p < 0.0001). This study highlights the need for the holistic contribution of the family to be considered in the clinical management of pediatric migraines.

New Daily Persistent Headache in a Pediatric Population

INTRODUCTION

New daily persistent headache (NDPH) is a primary headache disorder characterized by an intractable, daily, and unremitting headache lasting for at least 3 months. Currently, there are limited studies in the pediatric population describing the characteristics of NDPH.

OBJECTIVE

The objective of the current study is to describe the characteristics of NDPH in pediatric patients presenting to a headache program at a tertiary referral center.

METHODS

The participants in the current study were pediatric patients who attended the Headache Clinic at Children's National Hospital between 2016 and 2018. All patients seen in the Headache Clinic were enrolled in an institutional review board-approved patient registry.

RESULTS

Between 2016 and 2018, NDPH was diagnosed in 245 patients, representing 14% of the total headache population. NDPH patients were predominantly female (78%) and white (72%). The median age was 14.8 years. The median pain intensity was 6 of 10 (standard deviation = 1.52). Most patients reported experiencing migrainous features, namely, photophobia (85%), phonophobia (85%), and a reduced activity level (88%). Overall, 33% of patients had failed at least 1 preventive medication, and 56% had failed at least 1 abortive medication. Furthermore, 36% of patients were additionally diagnosed with medication overuse headache.

CONCLUSION

NDPH is a relatively frequent disorder among pediatric chronic headache patients. The vast majority of these patients experience migrainous headache characteristics and associated symptoms and are highly refractory to treatment-as evidenced by a strong predisposition to medication overuse headache and high rates of failed preventive management.

Short-Term and Long-Term Effectiveness of Intensive Interdisciplinary Pain Treatment for Children and Adolescents with Chronic Headache: A Longitudinal Observation Study

Pediatric chronic headache causes significant impairment to those affected and bears the risk of aggravation into adulthood. Intensive interdisciplinary pain treatment (IIPT) was found to positively affect pain-related and emotional outcomes in pediatric patients with chronic pain up to 4 years after treatment. This study was aimed at investigating the effect of IIPT on solely pediatric chronic headache patients. As part of a longitudinal observation study, n = 70 children and adolescents with chronic headache receiving IIPT were included, of which n = 47 completed the assessment at four assessment time points: before treatment (PRE) and at three follow-ups (6-MONTH FOLLOW-UP, 1-YEAR FOLLOW-UP, and 4-YEAR FOLLOW-UP). Pain-related (pain intensity, pain-related disability, school absence), as well as psychological outcome domains (anxiety, depression), were investigated. The results support the short-term and long-term efficacy of IIPT for pediatric chronic headache patients regarding the pain-related outcome measures by significant reductions from PRE to all follow-up measure points. For anxiety and depression, only short-term improvements were found. Future studies should specifically focus on the identification of methods to consolidate the beneficial short-term effects of IIPT on psychological outcome domains in the long term.

Comparison of Children with Migraine and Those with Tension-Type Headache for Psychiatric Symptoms and Quality of Life

This study compared the severity of depression, anxiety, somatization, anxiety sensitivity, sleep disturbances, and quality of life (QoL) among children with migraine, children with tension-type headache (TTH), and healthy children. A total of 37 children with migraine, 22 with TTH, and a healthy control group (n = 35) participated in this study. Children with migraine exhibited higher depression and somatization and lower QoL scores than those in the control group. General sleep disturbances, bedtime resistance, sleep onset delay, sleep duration, sleep anxiety, night wakings, sleep-disordered breathing, and daytime sleepiness scores were also higher in those in the migraine group than in the control group. Regression models indicated that the severity of headache and depression scores significantly affected the QoLs of children with headache disorder as a whole. Migraine is associated with depression, somatization, sleep disturbances, and poor QoL, whereas TTH is associated with only sleep disturbances in childhood. The impact of headache on the QoL occurs mainly through the headache-specific and psychiatric factors.

Medication Overuse Withdrawal in Children and Adolescents Does Not Always Improve Headache: A Cross-Sectional Study

Background: MOH can be diagnosed in subjects with headache occurring 15 days/month in association with a regular medication overuse, but its existence is not universally accepted. ICHD-3 redefined criteria for MOH, removing the criterion associating drug suspension with headache course. The aim of our study was to compare the rate of patients diagnosed with medication overuse headache (MOH) according to ICHD-2 and ICHD-3 criteria, to verify the degree of concordance. The secondary aim was to verify if drug withdrawal was really associated with pain relief. Methods: In this cross-sectional study, we retrospectively analyzed a sample of 400 patients followed for primary chronic headache at the Headache Center of Bambino Gesù Children's Hospital. We then selected those presenting with a history of medication overuse, and we applied both ICHD-2 and ICHD-3 criteria to verify in which patients the criteria would identify a clinical diagnosis of MOH. Results: We identified 42 subjects (10.5%) with MOH; 23 of them (55%) presented a relief of headache withdrawing drug overuse. Regarding the applicability of the ICHD-2 criteria, 43% of patients (18/42) fulfilled all criteria, while all ICHD-3 diagnostic criteria were satisfied in 76% of patients (32/42). Eighteen patients (43%) satisfied both ICHD-2 and ICHD-3 criteria, while 10 patients (24%) did not satisfy either diagnostic criterion. Conclusions: Our study suggests that in children and adolescents, withdrawing medication overuse is not always associated with a clinical benefit. Therefore, though allowing a MOH diagnosis in a higher rate of patients as compared to ICHD-2, the application of ICHD-3 criteria does not guarantee a true a causal relationship between medication overuse and headache worsening.

The impact of parental attitudes toward children with primary headaches

There is a lack of data on parental attitudes toward children with primary headaches. The aim of this study is to determine whether there is a relationship between primary headaches and parental attitudes in the pre-adolescent pediatric population. In this cross-sectional study, 195 children with primary headache and 43 healthy children aged 9-16 years were included. A questionnaire for sociodemographic variables, visual analog scale (VAS), Social Anxiety Scale and Depression Inventory for Adolescents and Children, and Parental Attitudes Determining Scale (PATS), which is an attitude measure specifically designed to evaluate psychological adjustment, were administered. Of 195 children (female/male ratio: 89/106, mean age: 12.59 ± 1.09 years), episodic migraine (n = 90), chronic migraine (n = 25), and tension-type headache (n = 80) were evaluated. There was no significant difference among headache groups and healthy subjects in terms of depression, anxiety, and fathers' attitude scale scores. However, there were significant differences in mean mothers' attitude scale scores and VAS scores (p = .002, p = .000). Mean oppressive-authoritarian attitude subscale scores of mothers' was significantly higher in children with chronic migraine (p = .000). A relationship between depression and VAS scores among all patient groups was detected (p = .000). Parental age was negatively related to PATS scores of children with episodic migraine and tension-type headache (p = .037 and p = .036). Parental attitudes may elevate psychiatric symptoms and influence children's perception of pain intensity and result in chronification of headache. Our findings support that mothers' attitude toward children with chronic migraine has strong impacts on the child's pain experience.

Chronic Daily Headache in Children and Adolescents: A Multi-Faceted Syndrome

Chronic daily headache (CDH) is a multi-faceted, often complex pain syndrome in children and adolescents. Chronic daily headache may be primary or secondary. Chronic migraine and chronic tension-type are the most frequent subtypes. Chronic daily headache is co-morbid with adverse life events, anxiety and depressive disorders, possibly with other psychiatric disorders, other pain syndromes and sleep disorders; these conditions contribute to initiating and maintaining CDH. Hence, early management of episodic headache and treatment of associated conditions are crucial to prevention. There is evidence for the benefit of psychological therapies, principally relaxation and cognitive behavioral, and promising information on acupuncture for CDH. Data on drug treatment are based primarily on open label studies. The controversies surrounding CDH are discussed and proposals for improvement presented. The multifaceted nature of CDH makes it a good candidate for a multi-axial classification system. Such an approach should facilitate biopsychosocial management and enhance consistency in clinical research.

Depression and insomnia are independently associated with satisfaction and enjoyment of life in medication-overuse headache patients

Objective Medication-overuse headache is often comorbid with emotional disturbances and disordered personality traits. The aim of the present study was to determine whether depression and insomnia complaints were associated with satisfaction and enjoyment with one's own life in medication-overuse headache patients, and whether insomnia complaints were able to explain part of the variance of Quality of Life explained by depression. Methods Participants were 187 consecutive adult outpatients admitted to the Regional Referral Headache Centre of the Sant'Andrea Hospital in Rome, Italy. Patients were administered the Quality of Life Enjoyment and Satisfaction Questionnaire, the Beck Depression Inventory - II, and the Athens Insomnia Scale. Results The Beck Depression Inventory was associated with all the dimensions of the Quality of Life Enjoyment and Satisfaction Questionnaire, with more severe depression being associated independently with lower satisfaction and enjoyment with one's own life. The Athens Insomnia Scale was independently and significantly associated only with physical health, such that patients with more insomnia complaints were 3.1 times ( p < 0.001) more likely to report lower physical health satisfaction. Conclusions Our findings confirmed that medication-overuse headache patients has a negative impact on quality of life and suggested that depression and insomnia were independently associated with satisfaction and enjoyment of life in medication-overuse headache patients. The early recognition and appropriate treatment of comorbid psychopathological symptoms are crucial to improve satisfaction and enjoyment of life in medication-overuse headache patients.

Comorbid Psychological Conditions in Pediatric Headache

Children and adolescents with chronic daily headaches (CDH) often have comorbid psychological conditions, though their prevalence is unclear. Pediatric patients with CDH may have higher rates of disorders such as anxiety and depression. However, some researchers have found that scores on depression and anxiety screening measures for pediatric patients with migraine are within reference range. Barriers to identify patients with psychiatric disorders have included limited validated screening tools and lack of available mental health resources. Several validated screening tools have recently been used in studies of pediatric patients with CDH. Once identified, treatment of comorbid psychological conditions may lead to improved functioning and headache outcomes.

Risk factors of chronic daily headache or chronic migraine

Chronic daily headache (CDH) is a common neurological condition that affects 1-4 % of the general population. Most individuals with CDH originally suffered from episodic headaches, but over time, this developed into CDH. Although the pathophysiology of CDH is not fully understood, recent clinical and epidemiological studies suggest some risk factors that are associated with an increased risk of transformation from episodic headaches. If risk factors can be identified, they could provide a base for aggressive preventive intervention and thus decrease the transformation from episodic headaches to eventual CDH. In this article, we review and summarize the current data on risk factors for CDH.

Psychiatric comorbidity in childhood and adolescence headache

Primary headaches among children and adolescents have a substantial impact on quality of life, daily activities, social interaction, and school performance in combination with psychopathological symptoms. The main purpose of the present paper is to summarize clinical and epidemiological evidence for psychiatric comorbidity among children and adolescents with headaches, to describe how evidence in headache research suggest different pathways involved in the development and maintenance of these comorbid conditions, and finally suggest some elements professionals may find helpful to assess the scope of complaints, related functional impairment, and potential precipitating factors in planning of more targeted treatments.

Psychometric properties of the stagnation scale in medication overuse headache patients

Background

Medication-overuse headache (MOH) is often comorbid with emotional disturbances, contributing to poorer outcomes. The aims of the present study were to assess the psychometric properties of the Stagnation Scale in a sample of MOH patients, and to compare two factor models: a three-factor model reported in previous studies and a proposed bi-factor model.

Methods

Consecutive adult outpatients (N = 310) admitted to the Regional Referral Headache Centre of the Sant’Andrea Hospital in Rome (Italy) were administered the Stagnation Scale and two questionnaires measuring depression and perceived disability.

Results

The original three-factor model demonstrated an adequate fit to the data (χ²₁₀₁ = 238.70; p < 0.001; Root Mean Square Error of Approximation [RMSEA] = 0.07; 90% CI of RMSEA = 0.06 / 0.08; Comparative Fit Index [CFI] = 0.98; Weighted Root Mean Square Residual [WRMR] = 0.75). However, the bi-factor model had a comparable or even better fit, with a RMSEA of 0.05 (90% CI: 0.04 / 0.07), providing strong evidence for an absolute fit to the data (χ²₈₈ = 161.43; p < 0.001; RMSEA = 0.05; 90% CI of RMSEA = 0.04 / 0.07; CFI = 0.99; WRMR = 0.56). The stagnation general factor and all the group factors correlated significantly and positively with convergent measures.

Conclusions

There is support for the use of the Stagnation Scale in MOH patients, with the goal of better understanding the role of psychological factors in the evolution and course of the disorder.

Medication overuse in children and adolescents

Medication overuse is not uncommon among children and adolescents with primary headache disorders. Medication overuse in adults is associated with increased headache frequency and reduced effectiveness of acute and preventive medications. These issues probably exist in children. While withdrawal of overused medications is generally recommended, it may not result in improved headache frequency in all patients. This review summarizes what is known about predicting the response to medication withdrawal. Strategies for managing children and adolescents with medication overuse are also offered.

Randomized controlled trial of the acceptability, feasibility, and preliminary effects of a cognitive behavioral skills building intervention in adolescents with chronic daily headaches: a pilot study

INTRODUCTION

The treatment challenge of adolescents with chronic daily headaches (CDHs) creates an urgent need for evidence-based interventions. Therefore the purpose of this pilot study was to evaluate the acceptability, feasibility, and preliminary effects of a brief cognitive behavioral skills building intervention with 36 adolescents, 13 to 17 years of age, who had CDHs and mild to moderate depressive symptoms.

METHODS

Participants were randomly assigned either to the Creating Opportunities for Personal Empowerment-Headache Education Program (COPE-HEP) or to a headache education comparison group.

RESULTS

Adolescents and parents found the COPE-HEP to be highly acceptable. Medium to large positive effects were demonstrated on the adolescents' depression in both groups and on anxiety and beliefs in the COPE-HEP group. COPE-HEP offered additional benefits of a larger decrease in adolescent anxiety over time and stronger beliefs in the teens' ability to manage their headaches.

DISCUSSION

Adolescents with CDHs and elevated depressive/anxiety symptoms should be offered headache hygiene education plus cognitive-behavioral skills building interventions. A full-scale trial to determine the more long-term benefits of COPE-HEP is now warranted.

Anxiety, depression and school absenteeism in youth with chronic or episodic headache

Chronic daily headache (CDH) is relatively common among children. Although comorbid conditions have been extensively studied in adults, they have not been assessed in the pediatric CDH population. Accordingly, the authors assessed several conditions known to be associated with CDH in adult patients in children with either CDH or episodic headache. The influence of CDH or episodic headache on the number of school days missed was also assessed.

BACKGROUND:

Chronic daily headache (CDH) in children has been documented in general and clinical populations. Comorbid psychological conditions, risk factors and functional outcomes of CDH in children are not well understood.

OBJECTIVES:

To examine anxiety and depression, associated risk factors and school outcomes in a clinical population of youth with CDH compared with youth with episodic headache (EH).

METHODS:

Data regarding headache characteristics, anxiety, depression and missed school days were collected from 368 consecutive patients eight to 17 years of age, who presented with primary headache at a specialized pediatric headache centre.

RESULTS:

A total of 297 patients (81%) were diagnosed with EH and 71 were diagnosed with CDH. Among those with CDH, 78.9% presented with chronic tension-type headache and 21.1% with chronic migraine (CM). Children with CDH had a higher depression score than the standardized reference population. No difference was observed for anxiety or depression scores between children with CDH and those with EH. However, children with CM were more anxious and more depressed than those with chronic tension-type headache. Youth experiencing migraine with aura were three times as likely to have clinically significant anxiety scores. Headache frequency and history were not associated with psychopathological symptoms. Children with CDH missed school more often and for longer periods of time.

CONCLUSIONS:

These findings document the prevalence of anxiety, depression and school absenteeism in youth with CDH or EH. The present research also extends recent studies examining the impact of aura on psychiatric comorbidity and the debate on CM criteria.

Screening for psychiatric comorbidity in children with recurrent headache or recurrent abdominal pain

BACKGROUND

Recurrent pain symptoms in children are associated with psychiatric comorbidities that could complicate treatment. We investigated the prevalence of psychiatric comorbidity in children with recurrent headache or recurrent abdominal pain and evaluated the screening potential of the Strength and Difficulties Questionnaire compared with the Development and Well-Being Assessment (DAWBA).

METHODS

Eighty-three outpatients aged 5-17 years attending a tertiary medical center for a primary diagnosis of migraine (n = 32), tension-type headache (n = 32), or recurrent abdominal pain (n = 19), and 33 healthy matched controls completed the brief self-reporting Strength and Difficulties Questionnaire followed by the Development and Well-Being Assessment. Findings were compared among groups and between instruments.

RESULTS

The pain groups were characterized by a significantly higher number of Development and Well-Being Assessment diagnoses (range 0-11) than controls and a significantly greater prevalence (by category) of Development and Well-Being Assessment diagnoses (P < 0.001 for both). Anxiety and depression were the most prevalent Development and Well-Being Assessment diagnoses. Comorbidities were more severe in the headache groups than the controls (P < 0.001). In general, any diagnosis by the Development and Well-Being Assessment was associated with a significantly higher Strength and Difficulties Questionnaire score (P < 0.001). Abnormal scores on the emotional, conduct, and hyperactivity Strength and Difficulties Questionnaire scales were significantly predictive of a Development and Well-Being Assessment diagnosis (P < 0.003).

CONCLUSION

Children referred to specialized outpatient pediatric units for evaluation of recurrent pain are at high risk of psychopathology. The Strength and Difficulties Questionnaire may serve as a rapid cost-effective tool for initial screening of these patients.

Headache and comorbidity in children and adolescents

Headache is one of the most common neurological symptom reported in childhood and adolescence, leading to high levels of school absences and being associated with several comorbid conditions, particularly in neurological, psychiatric and cardiovascular systems. Neurological and psychiatric disorders, that are associated with migraine, are mainly depression, anxiety disorders, epilepsy and sleep disorders, ADHD and Tourette syndrome. It also has been shown an association with atopic disease and cardiovascular disease, especially ischemic stroke and patent foramen ovale (PFO).

Chronic daily headache in children and adolescents: science and conjecture

SUMMARY Chronic daily headache comprises a group of headache disorders in which headaches occur almost daily or continuously over several months. Although chronic daily headache is one of the most common chronic pain disorders in pediatrics, data on pathophysiological mechanisms and relative efficacy of treatments remain sparse. In this review, we aim to provide contemporary information on classification, epidemiology, etiology and treatment of pediatric chronic daily headache based on extant empirical data when available, or general consensus in the field when not.

Psychiatric comorbidity in pediatric chronic daily headache

OBJECTIVES

The objectives of this study were to assess comorbid psychiatric diagnoses in youth with chronic daily headache (CDH) and to examine relationships between psychiatric status and CDH symptom severity, as well as headache-related disability.

METHODS

Standardized psychiatric interviews (Kiddie Schedule for Affective Disorders and Schizophrenia, KSADS) were conducted with 169 youth ages 10-17 diagnosed with CDH. Participants provided prospective reports of headache frequency with a daily headache diary and completed measures of symptom severity, headache-related disability (PedMIDAS) and quality of life (PedsQL).

RESULTS

Results showed that 29.6% of CDH patients met criteria for at least one current psychiatric diagnosis, and 34.9% met criteria for at least one lifetime psychiatric diagnosis. No significant relationship between psychiatric status and headache frequency, duration, or severity was found. However, children with at least one lifetime psychiatric diagnosis had greater functional disability and poorer quality of life than those without a psychiatric diagnosis.

DISCUSSION

Contrary to research in adults with chronic headaches, most youth with CDH did not appear to be at an elevated risk for comorbid psychiatric diagnosis. However, patients with a comorbid psychiatric diagnosis were found to have higher levels of headache-related disability and poorer quality of life. Implications for treatment are discussed.

Medication overuse headache in school-aged children: more common than expected?

OBJECTIVE

To investigate the prevalence of medication overuse headache (MOH) in a group of children and adolescents seen for headache in a third-level center in Italy.

BACKGROUND

Epidemiological studies indicate a prevalence of MOH in children and adolescents between 0.3 and 0.5%; no data are available for the Italian population.

METHODS

We studied a group of first-seen children and adolescents (118 patients, 43.2% male and 56.8% female, mean age: 11.9 years). A detailed history was taken, using criteria defined by Olesen et al to assess the presence of MOH. Statistical correlations between demographic and diagnostic variables were assessed.

RESULTS

Eleven (9.3%) of our patients presented MOH; in the group with chronic daily headache, the prevalence raised to 20.8%. At follow up, after introduction of a more rationale treatment, most patients improved, but 2 of them reported a worsening of their headache.

CONCLUSIONS

We believe that a strong warning regarding medication overuse in headache therapy is essential for pediatricians and neuropsychiatrists.

Characteristics of highly impaired children with severe chronic pain: a 5-year retrospective study on 2249 pediatric pain patients

BACKGROUND

Prevalence of pain as a recurrent symptom in children is known to be high, but little is known about children with high impairment from chronic pain seeking specialized treatment. The purpose of this study was the precise description of children with high impairment from chronic pain referred to the German Paediatric Pain Centre over a 5-year period.

METHODS

Demographic variables, pain characteristics and psychometric measures were assessed at the first evaluation. Subgroup analysis for sex, age and pain location was conducted and multivariate logistic regression applied to identify parameters associated with extremely high impairment.

RESULTS

The retrospective study consisted of 2249 children assessed at the first evaluation. Tension type headache (48%), migraine (43%) and functional abdominal pain (11%) were the most common diagnoses with a high rate of co-occurrence; 18% had some form of musculoskeletal pain disease. Irrespective of pain location, chronic pain disorder with somatic and psychological factors was diagnosed frequently (43%). 55% of the children suffered from more than one distinct pain diagnosis. Clinically significant depression and general anxiety scores were expressed by 24% and 19% of the patients, respectively. Girls over the age of 13 were more likely to seek tertiary treatment compared to boys. Nearly half of children suffered from daily or constant pain with a mean pain value of 6/10. Extremely high pain-related impairment, operationalized as a comprehensive measure of pain duration, frequency, intensity, pain-related school absence and disability, was associated with older age, multiple locations of pain, increased depression and prior hospital stays. 43% of the children taking analgesics had no indication for pharmacological treatment.

CONCLUSION

Children with chronic pain are a diagnostic and therapeutic challenge as they often have two or more different pain diagnoses, are prone to misuse of analgesics and are severely impaired. They are at increased risk for developmental stagnation. Adequate treatment and referral are essential to interrupt progression of the chronic pain process into adulthood.

Annual research review: functional somatic symptoms and associated anxiety and depression--developmental psychopathology in pediatric practice

BACKGROUND

Medically unexplained physical symptoms, commonly referred to as functional somatic symptoms (FSS), are common in pediatric medical settings and associated with suffering, impairment, and medical help seeking. The association of pediatric FSS with anxiety and depressive symptoms and disorders across the life span is reviewed.

METHOD

Review and critique of controlled studies examining cross-sectional and longitudinal associations of FSS with anxiety and depressive symptoms and disorders in community-based and clinical samples of children and adolescents.

RESULTS

FSS are consistently associated cross-sectionally with anxiety and depressive symptoms and disorders in childhood and adolescence, and the likelihood of associated anxiety and depression increases with the number of reported FSS. The presence of one or more FSS early in life is associated with an increased likelihood of multiple FSS and anxiety and depressive symptoms and disorders later in life, and anxiety and depressive symptoms and disorders in childhood are associated with subsequent multiple FSS.

CONCLUSION

Strong associations between FSS, anxiety, and depression across the life span suggest the need to reconsider existing nosology and reconceptualize symptomatic relationships. Large, population-based longitudinal studies of FSS, anxiety, and depressive symptoms and disorders are needed to establish temporal relationships between the various symptoms and conditions.

Attention in children and adolescents with headache

OBJECTIVE

The previous studies reporting consistent visual reaction times slowing in patients with migraine prompted us to verify if headache could be associated to a broader impairment of attention. This study aims to undertake a thorough investigation of attentional performance by extending the evaluation to children with primary headache of different types.

METHODS

We compared 62 children with headache (14 migraineurs with aura, 29 without aura and 19 with tension type headache) and 52 controls without headache, matched for age, sex, and intelligence using Conners' Continuous Performance Test.

RESULTS

The 3 clinical groups did not differ in attentional measures. The headache patients, collapsed in 1 single sample, had mean scores in Hit Reaction Time significantly different from those of controls and also had a higher percentage of atypical scores in 2 indices of the Conners' Continuous Performance Test (faster mean reaction time and more commissions).

CONCLUSIONS

Our results confirm the presence of an association between attentional problems and headache that may impact academic learning and daily activities on the long term. The finding that the 3 clinical groups did not show significant differences in attentional performance supports the hypothesis that migraine and tension headache form a continuum that may share the same pathophysiological mechanisms. These results are discussed considering that neurotransmitters and the cerebral circuits subserving headache, personality profile, and attention could overlap, thus predisposing these children to even mild attention malfunctioning.

Chronic daily headache: helping adolescents help themselves with self-hypnosis

Although the evidence is clear that hypnosis has been an effective treatment for recurrent headaches in children, review of the literature revealed no previous reports of hypnosis for youth with the condition of chronic daily headache. Two adolescents with continuing chronic daily headaches were taught self-hypnosis through careful attention to individual strengths and finding the hypnotic elements within the clinical encounters. Self-reports of intensity, frequency, and duration of headaches described substantial benefit from learning and practicing self-hypnosis after little to no benefit from pharmacologic and other nonpharmacologic therapies. These results and analogous success with several other adolescents with chronic daily headache support the further use of self-hypnosis training for this condition. As a self-regulation technique that is quickly and easily learned by most young people, self-hypnosis training holds considerable promise for effectively treating and perhaps preventing chronic daily headaches in children and adolescents.

Quality of life impairment, disability and economic burden associated with chronic daily headache, focusing on chronic migraine with or without medication overuse: a systematic review

OBJECTIVE

To evaluate the evidence for quality of life (QoL) impairment, disability, healthcare resource use and economic burden associated with chronic daily headache (CDH), focusing on chronic migraine (CM) with or without medication overuse.

METHODS

A systematic review and qualitative synthesis of studies of patients/subjects with CDH that included CM, occurring on at least 15 days per month.

MAIN FINDINGS

Thirty-four studies were included for review (25 studies of patients and nine of subjects from the general population). CDH and CDH with medication overuse headache (MOH) were consistently associated with a lower QoL compared to control or episodic headache (EH) and CDH without MOH. CDH was consistently associated with greater disability and productivity loss, more consultations, more or longer hospitalizations and higher direct costs than EH. Data were not amenable to statistical pooling.

PRINCIPAL CONCLUSIONS

The findings of this review underline the detriment to QoL and the disabling nature of CDH, and in particular CM and CDH with MOH, and negative impact on workplace productivity compared to other types of headache.

Migraine and psychiatric comorbidity: a review of clinical findings

Migraine is an extremely common disorder. The underlying mechanisms of this chronic illness interspersed with acute symptoms appear to be increasingly complex. An important aspect of migraine heterogeneity is comorbidity with other neurological diseases, cardiovascular disorders, and psychiatric illnesses. Depressive disorders are among the leading causes of disability worldwide according to WHO estimation. In this review, we have mainly considered the findings from general population studies and studies on clinical samples, in adults and children, focusing on the association between migraine and psychiatric disorders (axis I of the DSM), carried over after the first classification of IHS (1988). Though not easily comparable due to differences in methodology to reach diagnosis, general population studies generally indicate an increased risk of affective and anxiety disorders in patients with migraine, compared to non-migrainous subjects. There would also be a trend towards an association of migraine with bipolar disorder, but not with substance abuse/dependence. With respect to migraine subtypes, comorbidity mainly involves migraine with aura. Patients suffering from migraine, however, show a decreased risk of developing affective and anxiety disorders compared to patients with daily chronic headache. It would also appear that psychiatric disorders prevail in patients with chronic headache and substance use than in patients with simple migraine. The mechanisms underlying migraine psychiatric comorbidity are presently poorly understood, but this topic remains a priority for future research. Psychiatric comorbidity indeed affects migraine evolution, may lead to chronic substance use, and may change treatment strategies, eventually modifying the outcome of this important disorder.

Psychiatric comorbidity and suicide risk in patients with chronic migraine

The aim of this study was to explore the impact of mental illness among patients with migraine. We performed MedLine and PsycINFO searches from 1980 to 2008. Research has systematically documented a strong bidirectional association between migraine and psychiatric disorders. The relationship between migraine and psychopathology has often been clinically discussed rather than systematically studied. Future research should include sound methodologically-based studies focusing on the interplay of factors behind the relationship between migraine, suicide risk, and mental illness.

Frequent headaches in the preadolescent pediatric population

Objectives: To estimate the prevalence of chronic daily headaches (CDH) and of high-frequency episodic headaches (HFEH) in preadolescent children from the general population.

Background: Early-onset cases of neurologic diseases often reflect increased biologic predisposition, specific risk factors, or both.

Methods: Of 2,173 children identified as the target sample, consents were obtained from 1,870 (86.0%), and analyzable data were provided by 1,547 (71.2%). Parents and children were interviewed using a questionnaire consisting of 97 questions, with a validated headache module (10 questions). Crude and adjusted prevalences of HFEH (10–14 headache days per month) and CDH (15 or more headache days per month) were calculated.

Results: The prevalence of CDH was 1.68% (girls 2.09%, boys 1.33%). The overall prevalence of HFEH was 2.52% (girls 2.8%, boys 2.3%). After adjusting for gender, age, parental history of headaches, income, and school of origin, the prevalence of CDH was higher in girls than in boys (2.2% vs 1.1%, p < 0.01) and in nonwhite vs white children (2.2% vs 1.2%, p < 0.01). Similar differences were seen for HFEH (girls 3.1%, boys 2.0%, p < 0.01), (nonwhite 3.1%, white 1.9%, p < 0.01). Income significantly contributed to the model.

Conclusion: High-frequency episodic headaches and chronic daily headaches are common in the preadolescent pediatric population. Health care providers and educators should be aware of the magnitude of the problem to properly identify and treat children with headaches.

Pediatric chronic daily headache associated with school phobia

BACKGROUND

Children and adolescents with school phobia sometimes complain of severe and persistent headaches that are diagnosed as chronic daily headache (CDH).

METHODS

We investigated 24 children with CDH and school phobia, and 26 children with CDH but without school phobia.

RESULTS

Of 24 children with CDH and school phobia, 4% had chronic migraine (CM), 46% had chronic tension-type headache (CTTH) and 50% had both CTTH and migraine. However, of 26 children with CDH but without school phobia, 61% had CM, 24% had CTTH, 11% had CTTH and migraine, and 4% had new daily-persistent headache. There was a significantly higher rate of CTTH and both CTTH and migraine in children with CDH and school phobia than that in children with CDH but without school phobia (P < 0.0001). All of the 24 children with CDH and school phobia were found to have psychiatric disorders. Of 24 children, 71% were found to have adjustment disorders, 21% were found to have anxiety disorders, and 8% were found to have conversion disorder. Of 26 children with CDH but without school phobia, only 20% were found to have psychiatric disorders. There was a significantly higher rate of psychiatric disorders in children with CDH and school phobia than in children with CDH but without school phobia (P < 0.0001).

CONCLUSIONS

Our study indicated that children with CDH and school phobia had problems in school and/or family and psychiatric disorders. They should be diagnosed and treated attentively not only for headaches but also for their psychosocial problems and psychiatric disorders.

Study on management of pediatric migraine by general practitioners in northern France

The study explored the awareness of the Haute Autorité de Santé (High Health Authority, HAS) guidelines for migraine management in children among a random sample of 100 general practitioners (GPs) dichotomised in an urban and a rural group. A questionnaire conducted by phone included questions on knowledge of pediatric migraine acute treatment and preventive therapy, referral to a child neurologist as well as GPs awareness of HAS recommendations in general. Although 45% of GPs argued they were prescribing ibuprofen as first-line abortive drug, only 3% were aware of the recommended dose. Only 48% of GPs were agreeing to initiate preventive therapy. Fifty percent of GPs stated that they knew HAS guidelines but only 24% stated that they had read them. The only significant difference between urban and rural GPs concerned the initiation of preventive therapy. Continuing educational programmes on the implementation of pediatric migraine guidelines is strongly needed.

Obsessive compulsive disorder and migraine: case report, diagnosis and therapeutic approach

Psychiatric disorders, notably mood and anxiety disorders, are frequently associated with migraine and chronic daily headaches. The obsessive-compulsive disorder (OCD) is included in the spectrum of anxiety disorders and may be a comorbid condition in headache patients. However, little information has been reported in the literature about this association. This is an important issue as OCD may contribute to the development or maintenance of treatment-resistant chronic headaches. In this paper, we describe a young female patient with refractory chronic migraine and OCD. Considerations on diagnosis, management and treatment of these comorbid conditions are presented.

[Management of chronic daily headache in children and adolescents]

Chronic daily headache (CDH) affects 2 to 4% of adolescent females and 0,8 to 2% of adolescent males. CDH is diagnosed when headaches occur more than 4 hours a day, for greater than or equal to 15 headache days per month, over a period of 3 consecutive months, without an underlying pathology. It is manifested by severe intermittent headaches, that are migraine-like, as well as a chronic baseline headache. Silberstein and Lipton divided patients into four diagnostic categories: transformed migraine, chronic tension-type headache, new daily-persistent headache, and hemicrania continua. The second edition of the International Classification of Headache Disorders did not comprise any CDH category as such, but provided criteria for all four types of CDH: chronic migraine, chronic tension-type headache, new daily-persistent headache, and hemicrania continua. Evaluation of CDH needs to include a complete history and physical examination to identify any possibility of the headache representing secondary headaches. Children and adolescents with CDH frequently have sleep disturbance, pain at other sites, dizziness, medication-overuse headache and a psychiatric comorbidity (anxiety and mood disorders). CDH frequently results in school absence. CDH management plan is dictated by CDH subtype, the presence or absence of medication overuse, functional disability and presence of attacks of full-migraine superimposed. Reassuring, explaining, and educating the patient and family, starting prophylactic therapy and limiting aborting medications are the mainstay of treatment. It includes pharmacologic (acute and prophylactic therapy) and nonpharmacologic measures (biobehavioral management, biofeedback-assisted relaxation therapy, and psychologic or psychiatric intervention). Part of the teaching process must incorporate life-style changes, such as regulation of sleep and eating habits, regular exercise, avoidance of identified triggering factors and stress management. Emphasis must be placed on preventive measures rather than on analgesic or abortive strategies. Stressing the reintegration of the patient into school and family activities and assessing prognosis are other issues to address during the first visit. There are limited data evaluating the outcome of CDH in children and adolescents.

Chronic tension-type headache in adolescents. Clinical and psychological characteristics analyzed through self- and parent-report questionnaires

OBJECTIVES

To analyze the relation between the symptoms reported by adolescents with chronic tension-type headache (CTTH) and their perception of their emotional and behavioral functioning.

METHODS

Two groups of adolescents (clinical group, n = 48; control group, n = 135) and their parents (clinical group, n = 42; control group, n = 128) were studied, respectively, with the Youth Self-Report Questionnaire and the Child Behavior Checklist. Moreover, a secondary analysis was performed, identifying another subgroup of adolescents who reported having headaches.

RESULTS

The clinical group of adolescents obtained higher scores than the control group in Internalizing Syndrome; Aggressive Behavior for Externalizing Syndrome; Social, Thought, and Attention Problems; and in all Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV)-oriented scales (except conduct problems). Differences between the two groups of parents were found in all the scales. The controls reporting headaches obtained interesting intermediate scores.

CONCLUSIONS

Adolescents with CTTH show greater emotional and behavioral problems than their healthy peers. Consequently, clinical approaches for proper diagnosis and treatment need to adopt a multidisciplinary prospective.
