ADHD Is Comorbid to Migraine in Childhood: A Population-Based Study

Anxiety, depression, and headache-related disability in a large pediatric clinic-based sample

OBJECTIVE

To explore the relationships among anxiety, depression, and headache-related disability in a pediatric clinic-based retrospective cross-sectional study.

BACKGROUND

Anxiety and depression are commonly considered comorbidities of headache disorders and are frequently seen in children and adolescents. These conditions can contribute to disability and may have a cumulative impact. In this study, we tested whether self-reported anxiety and/or depression in youth were associated with headache-related disability.

METHODS

This was a retrospective cross-sectional study of children ages 6-17 years old who completed a headache intake questionnaire at the time of a new outpatient neurology visit. Those who reported on behavioral health symptoms, involvement of a behavioral health provider (i.e., yes/no), and the PedMIDAS (a validated metric of headache-related disability) were included. The relationship between anxiety and/or depression and headache-related disability was examined.

RESULTS

Of the 12,660 questionnaires queried, 9118 met criteria for inclusion. Respondents were 64.0% female and had a median age of 13.5 years (interquartile range [IQR] 10.3, 15.7). Compared to patients without self-reported anxiety/depression, patients with anxiety and depression reported higher headache-related disability (M = 17.0, [IQR 6.0, 41.0]) even after accounting for covariates (estimated difference = 6.0, 95% confidence interval [CI: 4.4-7.5]). For participants with anxiety and/or depression, having a behavioral health provider was associated with greater headache-related disability (estimated difference = 7.0; 95% CI 4.6-9.3).

CONCLUSIONS

Patients with self-reported anxiety and/or depression reported higher headache-related disability. Having a behavioral health provider was associated with greater headache-related disability, indicating the complexity and high level of need for this population. Further research is needed to understand the directionality of these results; however, patients with headache as well as depression and or anxiety are a vulnerable group who may benefit from an integrated care model.

Efficacy and safety of levetiracetam for migraine prophylaxis in children: a systematic review and meta-analysis

Background

Levetiracetam (LEV), an antiepileptic drug, has been effective in adult migraine prevention but lacks extensive research in children. This study evaluates LEV's efficacy and safety for pediatric migraine prophylaxis.

Methods

We reviewed randomized controlled trials (RCTs) and non-RCTs in major databases through 8 January 2024, focusing on four efficacy endpoints and adverse drug reactions (ADRs). Data synthesis involved pooled relative risks or odds ratios for dichotomous outcomes and mean differences for continuous outcomes, using fixed- or random-effects models as appropriate.

Results

Eight studies with 190 participants showed that after taking LEV, the mean headache frequency decreased 5.19 per month (MD: -5.19, 95% CI: -7.11 to -3.27, p < 0.00001) and improved headache-free rates to 28% (95% CI: 0.17-0.41). More than 83% experienced a >50% reduction in monthly headache frequency. The migraine disability score decreased by 33.51 points (MD: -33.51, 95% CI: -38.46 to -28.55, p < 0.00001). ADR incidence did not significantly differ between LEV and control groups (RR: 1.06, 95% CI: 0.39 to 2.85, p = 0.91), with an overall ADR rate of 18% (95% CI: 0.13-0.24). The most common ADR was irritability (12%), leading to treatment discontinuation in 13% of cases (95% CI: 0.05-0.30).

Conclusion

LEV has shown good efficacy in preventing pediatric migraines. However, its safety requires further confirmation through more extensive and well-designed RCTs.

Risk of major mental disorders in the offspring of parents with migraine

BACKGROUND

Migraine has been associated with mental disorders, however whether parental migraine is associated with an increased risk of major mental disorders (MMDs) in offspring has not been investigated. We aimed to examine the risk of the development of MMDs in the offspring of parents with migraine compared with those of parents without migraine.

METHODS

This study used data derived from the Taiwan National Health Insurance Research Database. Offspring of parents with migraine and a control group consisting of offspring of parents without migraine matched for demographic and parental mental disorders were included. Cox regression was used to estimate the risk of MMDs, including schizophrenia, depressive disorder, bipolar disorder, autistic spectrum disorder (ASD), and attention deficit/hyperactivity disorder (ADHD). Sub-analyses stratified by the fathers and mothers were further performed to separately clarify the risks of MMDs among the offspring.

RESULTS

We included 22,747 offspring of parents with migraine and 227,470 offspring of parents without migraine as the controls. Parental migraine was significantly associated with an increased risk of ADHD (reported as hazard ratios with 95% confidence intervals: 1.37, 1.25-1.50), bipolar disorder (1.35, 1.06-1.71), and depressive disorder (1.33, 1.21-1.47) compared to the offspring of parents without migraine. Importantly, sub-analyses showed that only maternal migraine was significantly associated with these risks.

CONCLUSIONS

Due to the heavy burden of MMDs, healthcare workers should be aware of the risk of MMDs in the offspring of parents with migraine, particular in mothers.

Attention Deficit Hyperactivity Disorder in Adults With Migraine

INTRODUCTION

Several studies have shown increased occurrence of migraine in ADHD patients. However, there is less evidence on whether migraine patients also have a higher ADHD frequency. The aim of this paper is determining whether the prevalence of ADHD symptoms or impulsivity is higher in patients with episodic migraine.

METHODS

An observational cohort study has been conducted. Patients with episodic migraine were included. The ADHD Rating scale, the Adult ADHD Self-Report Scale, and the scale of impulsiveness of Plutchik were used.

RESULTS

The mean value of inattention, hyperactivity and impulsivity scores on the ADHD scale was 5 ± 3.8 in cases and 2.7 ± 2.2 in controls (p < .00001), 4 ± 3.2 in cases and 2.5 ± 2.4 in controls (p = .000621) and 2 ± 1.5 in cases and 1.1 ± 1 in controls (p = .000407), respectively.

CONCLUSION

Adults with migraine have a higher prevalence of ADHD symptoms. This should be considered when assessing these patients.

Primary headache disorders in Latin America and the Caribbean: A meta-analysis of population-based studies

BACKGROUND

In this manuscript, we aim to systematically estimate the pooled prevalence and incidence of primary headaches and its subtypes (migraine, tension-type headache, and chronic headaches) in Latin America and the Caribbean, describing its epidemiological profile and associated factors.

METHODS

We systematically searched PubMed/MEDLINE, Scopus, and LILACS (From conception to March 2021), for populational studies reporting the epidemiology of primary headaches and their associated factors in Latin America and the Caribbean. The data extraction was conducted independently. We performed random-effect model meta-analysis of prevalence (overall primary headaches and by subtypes) and associated factors, assessed potential sources of heterogeneity, the risk of bias, publication bias, and the evidence certainty (GRADE methodology).

RESULTS

We included 32 populational studies (38 subpopulations, n = 63,813). The prevalence of primary headaches was 41.4% (95% CI 31.1-52.2%; n = 54,357), 15% for migraine (95% CI 12.0-18.3; n = 53,658 individuals), 20.6% for tension-type headache (95% CI 12.4-30.2; n = 25,840), and 6% for chronic headaches (95% CI 3.3-9.6; n = 21,720), with high between-study heterogeneity. No incidence data was found. Female sex, white ethnicity, high BMI, comorbid mental health disorders, and low-back pain were associated with higher prevalence of primary headaches. The prevalence was less in rural areas.

CONCLUSION

In Latin America and the Caribbean, primary headaches are highly prevalent affecting young females disproportionally. The prevalence of chronic headaches is higher than in other systematic global and regional estimations. The presence of comorbidities as modifiable risk factors should encourage their integration as targets for community-based preventive and therapeutic interventions.

Case report: Look at my eyes

The comorbidity of migraine and Autism Spectrum Disorder (ASD) still remain unclear. In spite of plausible evidences of such comorbidity, there is a scarcity of populational studies focusing this hypothesis. The diagnosis of migraine in children with ASD is very challenge due to the large clinical heterogeneity and limited communication skills, particularly verbal abilities in young children and those with intellectual disability. ASD and migraine are chronic prevalent disorders sharing some pathophysiological changes (neurotransmission dysregulation, altered immune response, abnormal findings in the cortical minicolumn organization, and dysfunctions in the gut–brain axis), susceptibility genes (including calcium channel mutations and polymorphisms), and atypical sensory processing. Herein, we take advantage of a prototypical case of an adolescent with episodic migraine transformed to chronic, not responsive to preventive treatment, to explore the diagnostic workup and successful personalized clinical and therapeutical management.

Psychological Disorders, Adverse Childhood Experiences and Parental Psychiatric Disorders in Children Affected by Headache: A Systematic Review

BACKGROUND

Pediatric headaches have been linked to adverse life events or psychological factors in children and their families, with a complex and bidirectional association. Moreover, it is well-known that psychological stress can trigger headaches.

METHODS

We searched three databases for studies focusing on headaches and adverse events or psychological factors in children up to 12 years old or in their caregivers.

RESULTS

We included 28 studies. Child psychological factors, including internal and external symptoms, were commonly associated with all types of headaches. Sleep disturbances showed a positive association with headaches in 3 out of 5 studies. Family conflict and unhappiness were frequently found in children suffering with headaches, while single-parent families and divorce were not associated. Stressful environments and adverse life events, particularly bullying, were also found to be linked with headaches.

CONCLUSIONS

Childhood headaches represent an alarm bell for clinicians to investigate and treat psychological or psychiatric disorders in children and their family. Further studies are needed to elucidate the role of early-life adverse events in children and their families.

Interictal Cognitive Performance in Children and Adolescents With Primary Headache: A Narrative Review

Primary headache is a very common and disabling disease. The burden of pain and recurrent attacks may lead to a poor quality of life, anxiety and depression. An increased risk of low functioning and curricular performances in young patients with primary headache has been described. The mechanisms underlying the relationship between migraine and poor school achievement may be various and could be a reflection of weak cognitive skills. Data concerning the cognitive functioning in the free pain interval in pediatric age are under-investigated and results are far from conclusive. The present review article suggests that, though considered a benign disease, pediatric migraine may be associated to altered neuropsychological functioning in the interictal phase. Although children and adolescents with migraine generally have a normal intelligence, they may show a not homogeneous cognitive profile, characterized by possible difficulties in verbal skills, in particular comprehension abilities. Pediatric primary headache may present altered neuropsychological functioning involving attentional resources, processing speed and memory, particularly verbal memory. Given the impact that this disease can have on school performance and the tendency to persist from childhood to adulthood, a cognitive screening in young patients affected by primary headache is pivotal. Additional neuropsychological research using more homogenous methods is needed.

Association of Maternal Use of Triptans During Pregnancy With Risk of Attention-Deficit/Hyperactivity Disorder in Offspring

Importance

Triptans are commonly used in the treatment of migraine. Prenatal exposure to triptans may be associated with adverse fetal neurodevelopment; however, there is limited information about the long-term safety of triptan use during pregnancy.

Objective

To examine the association between maternal use of triptans during pregnancy and diagnosis and symptoms of attention-deficit/hyperactivity disorder (ADHD) among offspring.

Design, Setting, and Participants

This study used data from the Norwegian Mother, Father and Child Cohort Study (recruitment 1999-2008), linked to national health registries. Live-born singleton children born to women with migraine before or during pregnancy were included. Two analytic samples were defined: one to assess ADHD diagnosis and one to assess ADHD symptoms. Data were analyzed from May 1 to November 30, 2021.

Exposure

Maternal self-report of triptan use during pregnancy. Exposed children were compared with 2 groups of unexposed children whose mothers reported migraine (1) during pregnancy and (2) before pregnancy only.

Main Outcomes and Measures

An ADHD diagnosis was defined as diagnosis of hyperkinetic disorder or receipt of dispensed ADHD medication. Symptoms of ADHD at 5 years were measured by the Conners' Parent Rating Scale, where a higher score indicates more symptoms of ADHD. Cox proportional hazards regression models and generalized linear models with inverse probability weights were used to estimate weighted hazard ratios (HRs) and standardized mean differences, respectively, with 95% CIs.

Results

The ADHD diagnosis sample comprised 10 167 children (mean [SD] maternal age, 30.2 [4.6] years; 5231 boys [51.5%]), and the ADHD symptoms sample comprised 4367 children (mean [SD] maternal age, 30.6 [4.4] years; 2191 boys [50.2%]). Children were followed up for a mean (SD) of 10.6 (2.2) years. Children with prenatal triptan exposure had no increased risk of ADHD diagnosis compared with unexposed children whose mothers had migraine during pregnancy (weighted HR, 1.16; 95% CI, 0.78-1.74) and compared with unexposed children whose mothers had migraine only before pregnancy (weighted HR, 1.28; 95% CI, 0.84-1.94). There were no differences in ADHD symptom scores between exposed and unexposed children.

Conclusions and Relevance

The findings of this study suggest that there is no increased risk of ADHD among offspring associated with prenatal exposure to triptans.

Non-mental diseases associated with ADHD across the lifespan: Fidgety Philipp and Pippi Longstocking at risk of multimorbidity?

Several non-mental diseases seem to be associated with an increased risk of ADHD and ADHD seems to be associated with increased risk for non-mental diseases. The underlying trajectories leading to such brain-body co-occurrences are often unclear - are there direct causal relationships from one disorder to the other, or does the sharing of genetic and/or environmental risk factors lead to their occurring together more frequently or both? Our goal with this narrative review was to provide a conceptual synthesis of the associations between ADHD and non-mental disease across the lifespan. We discuss potential shared pathologic mechanisms, genetic background and treatments in co-occurring diseases. For those co-occurrences for which published studies with sufficient sample sizes exist, meta-analyses have been published by others and we discuss those in detail. We conclude that non-mental diseases are common in ADHD and vice versa and add to the disease burden of the patient across the lifespan. Insufficient attention to such co-occurring conditions may result in missed diagnoses and suboptimal treatment in the affected individuals.

The World Federation of ADHD International Consensus Statement: 208 Evidence-based conclusions about the disorder

BACKGROUND

Misconceptions about ADHD stigmatize affected people, reduce credibility of providers, and prevent/delay treatment. To challenge misconceptions, we curated findings with strong evidence base.

METHODS

We reviewed studies with more than 2000 participants or meta-analyses from five or more studies or 2000 or more participants. We excluded meta-analyses that did not assess publication bias, except for meta-analyses of prevalence. For network meta-analyses we required comparison adjusted funnel plots. We excluded treatment studies with waiting-list or treatment as usual controls. From this literature, we extracted evidence-based assertions about the disorder.

RESULTS

We generated 208 empirically supported statements about ADHD. The status of the included statements as empirically supported is approved by 80 authors from 27 countries and 6 continents. The contents of the manuscript are endorsed by 366 people who have read this document and agree with its contents.

CONCLUSIONS

Many findings in ADHD are supported by meta-analysis. These allow for firm statements about the nature, course, outcome causes, and treatments for disorders that are useful for reducing misconceptions and stigma.

Migraine and Tension-Type Headache Among Children and Adolescents: Application of International Headache Society Criteria in a Clinical Setting

INTRODUCTION

The International Headache Society criteria were written in order to help physicians establish a headache diagnosis. However, sometimes children with headache do not seem to fit any diagnosis. The purpose of our study was to assess the application of the criteria in a clinical setting.

METHODS

Medical records of children referred for primary headache to the pediatric neurology clinic at Bnai Zion Medical Center from 2008 to 2017 were assessed.

RESULTS

A total of 989 patients (range 6-18 years; 53% female) were assessed at our neurology clinic. Twenty-four percent (n = 241) were diagnosed with tension-type headache, 26% (n = 256) with migraine, and 4.5% (45) with mixed headache. In 41.5% (410), we were unable to reach a specific diagnosis. No differences in gender or age were found between the groups. Children in the migraine group used more analgesic treatments to stop the headache attacks compared with the tension-type headache group (50% vs 38%, P = .001). Patients diagnosed with tension-type headache reported having more emotional difficulties (P = .001). No significant differences were found in headache characteristics (ie, location, sidedness, character), frequency, or intensity between the younger children (ages 6-11) and the adolescents (ages 12-18) within either the tension-type headache or migraine groups.

CONCLUSIONS

Retrospective application of International Headache Society criteria in a large cohort of children with headaches failed to diagnose a specific type of headache in 41.5% of children. Migraine and tension-type headache were equally prevalent, and both constituted a major burden on our patients' everyday lives. We found no major differences in frequency, intensity, and characteristics of pain between younger children and adolescents.

Attention-deficit/hyperactivity disorder symptoms and sleep problems in preschool children: the role of autistic traits

BACKGROUND

Sleep problems are elevated in children with attention-deficit/hyperactivity disorder (ADHD). However, until now there has been comparatively little research on the role of autistic traits in this association. The current study examined the association between ADHD symptoms and sleep problems in Japanese preschool children and whether autistic traits might also be important for this relationship.

METHODS

Data were analyzed from 1053 children (average age 64.14 months, range 58-71; 50.3% male) that were drawn from the Tama Children's Survey (TCS). Parent-reported information was obtained on ADHD symptoms using the Strengths and Difficulties Questionnaire (SDQ) and autistic traits with the Social Responsiveness Scale Second Edition (SRS-2). Parents also provided information on three different categories of sleep problems experienced by their children - parasomnias, sleep disordered breathing and awakening/daytime problems. Ordinal logistic regression analysis was used to examine the associations.

RESULTS

In analyses adjusted for sociodemographic factors, the mother's mental health and child's emotional problems, compared to children with no ADHD symptoms or autistic traits, children with only ADHD symptoms had significantly increased odds for only one of 11 individual sleep problems - waking in a negative mood. In contrast, children with comorbid ADHD symptoms and autistic traits had elevated odds for five sleep problems with odds ratios ranging from 2.10 (takes time to become alert in the morning) to 3.46 (excessive body movement while sleeping).

CONCLUSIONS

Sleep problems may be especially elevated in children with comorbid ADHD symptoms and autistic traits.

Resilience and vulnerability in adolescents with primary headaches: A cross-sectional population-based study

BACKGROUND

A scarcity of studies on the role of resilience resources (RRs) and vulnerability risk (VR) in children and adolescents with primary headache hampers the development of a risk-resilience model for pediatric headaches.

OBJECTIVE

To examine the extent to which headache frequency and diagnosis are associated with RRs and VR and explore possible predictors of low RRs and high VR in a cross-sectional population-based study in adolescents.

METHODS

This is a cross-sectional population study conducted in a small city in Brazil (Delfinópolis). Consents and analyzable data were obtained from 339/378 adolescents (89.7%). RRs and VR were assessed using the validated Brazilian version of the Resiliency Scales for Children and Adolescents, completed by the adolescents. Parents filled a structured questionnaire assessing sociodemographic and headache characteristics, as well as the Brazilian-validated version of the Strengths and Difficulties Questionnaire added to the impact supplement to evaluate the adolescent's psychosocial adjustment skills. Teachers completed a structured questionnaire about the students' school performance.

RESULTS

A higher frequency of headache was associated with lower RRs (F_3,335  = 2.99, p = 0.031) and higher VR (F_3,335  = 4.05, p = 0.007). Headache diagnosis did not significantly influence the risk of having lower RRs or higher VR. In the exploratory analyses, females (OR 3.07; 95% CI: 1.16-9.3) and individuals with psychosocial adjustment problems (OR 7.5; 95% CI: 2.51-22.4) were predictors of low RRs, and prenatal exposure to tobacco (OR 5.6; 95% CI: 1.57-20.9) was a predictor of high VR in adolescents with primary headache.

CONCLUSIONS

The risk of low RRs and high VR was associated with a higher headache frequency, but not with headache diagnosis. These findings may contribute to the development of a risk-resilience model of headaches in the pediatric population and help identify novel targets and develop effective resources for successful interventions.

Negative effects of accompanying psychiatric disturbances on functionality among adolescents with chronic migraine

Background

Chronic migraine is a condition with gradually increasing prevalence among adolescents which causes severe headaches resulting in functionality loss. Factors contributing to migraine becoming chronic and negatively affecting quality of life in adolescence are still unclear. Parallel with these, we aimed to examine the effect of psychiatric symptoms on headache severity and functionality loss among adolescents with chronic migraine.

Methods

We evaluated features of 50 adolescents who were diagnosed with chronic migraine according to International Classification of Headache Disorders-3 for the first time in their lives by an experienced neurologist. Sociodemographic and clinical data were collected and Pediatric Migraine Disability Assessment Score, Visual Analogue Score and DSM-5 Level 1 Cross-Cutting Symptom Measure Scores (CCSM-5) were evaluated. Semi-structured psychiatric interviews were done to those who scored higher than cut-off scores on CCSM-5. Healthy control group was constituted of cases which had similar age and sex distribution to case group.

Results

Majority of the case group was female (%78). There was a positive correlation between headache severity and computerized tomography history in emergency department. All of the psychiatric symptom scores were significantly higher in case group except for psychotic symptoms; but attention problems and manic symptoms clusters did not have significant difference according to the thresholds of CCSM-5. Receiving a psychiatric diagnosis did not affect frequency, severity or duration of headaches. There were also no relationship between depression/anxiety diagnosis and severity of headache/functionality loss.

Conclusion

Findings suggest that; more rational treatment methods with lesser functionality loss should be developed by adopting multidisciplinary and prospective approach via psychiatric screening for adolescents with chronic migraine.

ADHD: Current Concepts and Treatments in Children and Adolescents

Attention deficit hyperactivity disorder (ADHD) is among the most frequent disorders within child and adolescent psychiatry, with a prevalence of over 5%. Nosological systems, such as the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) and the International Classification of Diseases, editions 10 and 11 (ICD-10/11) continue to define ADHD according to behavioral criteria, based on observation and on informant reports. Despite an overwhelming body of research on ADHD over the last 10 to 20 years, valid neurobiological markers or other objective criteria that may lead to unequivocal diagnostic classification are still lacking. On the contrary, the concept of ADHD seems to have become broader and more heterogeneous. Thus, the diagnosis and treatment of ADHD are still challenging for clinicians, necessitating increased reliance on their expertise and experience. The first part of this review presents an overview of the current definitions of the disorder (DSM-5, ICD-10/11). Furthermore, it discusses more controversial aspects of the construct of ADHD, including the dimensional versus categorical approach, alternative ADHD constructs, and aspects pertaining to epidemiology and prevalence. The second part focuses on comorbidities, on the difficulty of distinguishing between "primary" and "secondary" ADHD for purposes of differential diagnosis, and on clinical diagnostic procedures. In the third and most prominent part, an overview of current neurobiological concepts of ADHD is given, including neuropsychological and neurophysiological researches and summaries of current neuroimaging and genetic studies. Finally, treatment options are reviewed, including a discussion of multimodal, pharmacological, and nonpharmacological interventions and their evidence base.

Migraine, attention deficit hyperactivity disorder and screen time in children attending a Sri Lankan tertiary care facility: are they associated?

BACKGROUND

Headache and Attention Deficit Hyperactivity Disorder (ADHD) are two relatively common, neuropsychiatric conditions seen in children. Recent studies have shown an association between these two disorders, which are otherwise distinct conditions. This study aims to assess the association between migraine and ADHD, as well as the association between screen-time and these two conditions, among children attending a Sri Lankan tertiary care facility. Possible associations will have important implications in the clinical management of these conditions.

METHODS

This was a comparative cross-sectional study of 226 children aged 5-14 years, attending clinics at a tertiary care hospital in Galle, Sri Lanka. Of them, 141 had a diagnosis of migraine and 85 did not have migraine. The presence or absence of ADHD and the use of screen-time among the two groups was analysed. Chi-square test and Mann-Whitney U test was used to assess the associations between these variables.

RESULTS

Approximately 5% of the children with migraine had clinically diagnosed ADHD, compared to 3.5% of those without migraine (p = 0.862). The median SNAP-IV scores (inter-quartile range) of the children with migraine and without migraine were 0.60 (0.27-1.00) and 0.44 (0.16-0.80) respectively (p = 0.014). There was no significant difference in screen-time hours per day between children with and without clinically diagnosed ADHD. However, a significant difference in median screen-time (hours per day) was observed between children with and without migraine (2.0 h and 1.0 h respectively; p = 0.012).

CONCLUSIONS

Our findings suggest that children with migraine are more likely to show features of hyperactivity/impulsivity and inattentiveness than those without migraine. While no association was found between clinically diagnosed ADHD and screen-time, migraine was associated with longer daily screen use. Screening for ADHD in children diagnosed with migraine may be of benefit. Further studies are required to understand the possible benefits of reducing screen-time in children with migraine.

Pediatric Migraine and Academics

PURPOSE OF REVIEW

The purpose of this review is to examine the multitude of factors which may impact learning and academic performance in patients with pediatric migraine.

RECENT FINDINGS

A range of associations of varying degree were noted between pediatric migraine and conditions such as ADHD, learning disabilities, sleep disorders, and psychiatric comorbidities with regard to headache pain and school functioning. Recent literature highlights the importance of sleep in relation to headache, mood disorders, and learning in youth and the emerging role of perfectionism. Children with migraine remain at risk for school related and learning difficulties which may be primarily due to pain, due to other medical and psychiatric comorbidities commonly found in this population, or a combination. The relationships are complex and further studies are needed to clearly elucidate the shared biological and environmental pathophysiologic mechanisms.

Prevalence of autism traits and attention-deficit hyperactivity disorder symptoms in a clinical sample of children and adolescents with chronic pain

Purpose

Recent research has suggested that autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) may be comorbid to pediatric chronic pain, but the empirical support is yet scarce. Therefore, the current study aimed to investigate the occurrence of traits and symptoms consistent with clinically significant ASD and ADHD in a group of children and adolescents with chronic debilitating pain and examine potential differences in pain and demographic variables between children with and without clinically significant traits and symptoms of ASD and ADHD.

Patients and methods

This cross-sectional study included 146 parent–child dyads (102 girls, 111 mothers, children 8–17 years) consecutively referred to a tertiary pain clinic. Parents completed the Social Responsiveness Scale to assess autistic traits, and Conners-3 to measure symptoms of ADHD in their children. Children completed the Lübeck Pain Questionnaire to evaluate experienced pain.

Results

Among children, 20 (13.7%) received scores consistent with clinically significant ASD and 29 (19.9%) received scores consistent with clinically significant ADHD, with a combined prevalence of clinically significant ASD/ADHD traits and symptoms of 26% of the total sample. Only 4.8% of children were previously diagnosed with either disorder. Among children with clinically significant ASD traits, girls were more prevalent, parents reported lower health, and the pain was more likely triggered by being in school. Among children with clinically significant ADHD symptoms, there were no gender differences and pain was more likely triggered by the family situation and new situations. No differences regarding pain intensity, duration, or frequency were found between children with and without clinically significant ASD traits or ADHD symptoms.

Conclusion

Children with debilitating chronic pain, particularly girls, may present with an elevated risk of having a comorbid, possibly high-functioning, neurodevelopmental disorder. Results suggest that clinical assessment of pediatric chronic pain should include screening for neurodevelopmental disorders.

Comorbidity of migraine with ADHD in adults

BACKGROUND

Migraine and Attention Deficit and Hyperactivity Disorder (ADHD) have been found to be associated in child and adolescent cohorts; however, the association has not been assessed in adults or otherwise healthy population. Assessing the comorbidity between ADHD and migraine may clarify the etiopathology of both diseases. Thus, the objective is to assess whether migraine (with and without visual disturbances) and ADHD are comorbid disorders.

METHODS

Participants from the Danish Blood Donor Study (N = 26,456, age 18-65, 46% female) were assessed for migraine and ADHD using the ASRS ver 1.1 clinically validated questionnaire and self-reported migraine in a cross-sectional study. Logistic regression was used to examine the comorbidity between migraine and ADHD, and their associated endophenotypes.

RESULTS

Migraine was strongly associated with ADHD (OR = 1.8, 95% CI = 1.5-2.1), (238/6152 vs 690/19,376). There was a significant interaction between age and gender, with comorbidity increasing with age and female sex. Post-hoc analysis showed that migraine with visual disturbance was generally associated with a marginally higher risk of ADHD and this was independent of ADHD endophenotypes.

CONCLUSION

Migraine and ADHD were demonstrated to be comorbid disorders; the association with ADHD was most prominent for participants with migraine with visual disturbances. Future studies will elucidate which genetic and environmental factors contribute to migraine-ADHD comorbidity.

A case report and literature review of autism and attention deficit hyperactivity disorder in paediatric chronic pain

Psychiatric disorders are common in paediatric patients with chronic pain, but the overall prevalence of comorbid neurodevelopmental disorders is unclear. We report on a case of severe chronic pain in a child with undiagnosed comorbid autism spectrum disorder and attention deficit hyperactivity disorder, where significant improvements in pain and function occurred following methylphenidate medication and parental behavioural training.

CONCLUSION

The inclusion of behavioural assessment and screening for neurodevelopmental comorbidity may be essential in addressing complex paediatric chronic pain.

Recent advances in the management of chronic migraine in children

INTRODUCTION

Migraine is a chronic-recurrent disorder that progresses in some adults and also in many children. Chronic migraine (CM) is the clinical result of this process. Since migraine does not progress in most children, identifying the risk factors for progression is an important public health priority that should be matched by evidence-based treatment. Areas covered: Herein we conduct a systematic review on the comorbidities and treatment of CM in children and adolescents in the last ten years, summarizing evidence-based recommendations for disease management. Expert commentary: By conceptualizing CM as the result of migraine progression from an episodic form, we suggest avoiding CM at the outset through development of aggressive, preventive interventions as the goal of headache management in the pediatric population. Key interventions include: Decreasing headache frequency with behavioral and pharmacologic interventions; Monitoring body mass index and encouraging maintenance of normal weight; Avoiding medication overuse; Screening and treating comorbidities.
