Childhood and adolescent migraine: A neuropsychiatric disorder?

Emotional Experience and Regulation in Juvenile Primary Headaches: A Cross-Sectional Pilot Study

A headache is the most common neurological symptom in children. Its subtypes are migraine (MH) and tension-type headache (TTH). Internalizing rather than externalizing symptoms are more frequent in children with headaches, but little is known about the reasons why. We aim to: (a) examine the interplay between emotional experience, affective regulation, and internalizing symptoms in children suffering from primary headaches and their caregivers; (b) identify potential predictors of children with migraines' internalizing symptoms. Fifty children and adolescents with a diagnosis of primary headaches and their caregivers were compared to a sample of fifty-one healthy peers and caregivers. Self-reports and parent-reports were administered. Results indicate higher negative affect and internalizing symptoms and lower bodily awareness of emotions in the clinical sample (n = 50; Mage = 11.66, SD = 2.25) compared to controls (n = 51; Mage = 11.73, SD = 2.32); mothers of TTH children self-reported lower emotional awareness and higher difficulties in engaging in goal-directed behavior; a higher frequency of headaches was associated with greater emotional regulation difficulties. Internalizing symptoms were predicted by higher self-reported negative affect and parent-reported internalizing symptoms, and lower self-reported ability in the verbal sharing of emotions. These findings suggest the importance of assessing the psychological features linked to children with primary headaches' psychological well-being.

Experiment in vivo: How COVID-19 Lifestyle Modifications Affect Migraine

Introduction: The coronavirus disease 2019 (COVID-19) pandemic represents a unified lifestyle modification model, which was developed by the globally applied measures. The lockdowns designed the perfect study settings for observing the interaction between migraine and the adopted changes in lifestyle. An experiment in vivo took place unexpectedly to determine how the lockdown lifestyle modifications can influence migraine.

Subsection 1: Overall lifestyle modifications during the pandemic: People stay home, and outdoor activities and public contacts are restricted. Sleep is disturbed. Media exposure and prolonged screen use are increased. Working conditions change. In-person consultations and therapies are canceled. The beneficial effects of short-term stress, together with the harmful effects of chronic stress, were observed during the pandemic.

Subsection 2: Short-term effects: Substantial lifestyle changes happened, and knowing how vulnerable migraine patients are, one could hypothesize that this would have resulted in severe worsening of headache. Surprisingly, even though the impacts of changing social conditions were significant, some patients (including children) experienced a reduction in their migraine during the first lockdown.

Subsection 3: Long-term effects: Unfortunately, headache frequency returned to the basal state during the second pandemic wave. The risk factors that could have led to this worsening are the long-term disruption of sleep and dietary habits, stress, anxiety, depression, non-compliance to treatment, and working during the pandemic.

Discussion: Sudden short-term lifestyle changes taking migraine patients out of their usual routine may be beneficial for headache management. It is not necessary to have a natural disaster in place for a drastic lifestyle modification with 6–8-week duration, if we know that this will improve migraine.

The Influence of Lifestyle Factors on the Burden of Pediatric Migraine

There is a gap in patient education and coaching of lifestyle factors related to pediatric migraine, which nurses are in a unique position to fill in order to provide comprehensive care to these patients. In order to help fill this gap, we conducted a targeted review of studies examining migraine and lifestyle factors in children and adolescents. Studies older than 2010, studies examining adults above the age of 18, studies not available in the English language, and secondary sources were excluded from the review. A final sample of 42 studies was included in this review. Lifestyle factors including stress, sleep, obesity, and diet were identified as playing a significant role in increasing the frequency, severity, and duration of migraine attacks in pediatric patients. Based on these findings, a framework is discussed for practical applications of this knowledge by nursing staff working in primary and specialty care clinics.

Migraine Symptoms Improvement During the COVID-19 Lockdown in a Cohort of Children and Adolescents

Background: Pediatric migraine is among the most common primary or comorbid neurologic disorders in children. Psychological stressors are widely acknowledged as potential triggers involved in recurring episodes of pediatric migraine. As the COVID-19 emergency may have affected the levels of stress perceived by children and adolescents with migraine, the present study was aimed to understand the effect of COVID-19 emergency on symptoms intensity and frequency in pediatric patients.

Methods: A cohort of 142 child and adolescent patients with a diagnosis of migraine was enrolled at the Child Neurology and Psychiatry Unit of the IRCCS Mondino Foundation in Pavia (Italy). Socio-demographic and clinical characteristics were obtained from medical records. An on-line survey was used to collect information on COVID-19 exposure, stress response to the lockdown period, anxious symptoms during COVID-19 emergency, as well as migraine symptoms intensity and frequency before and during the lockdown.

Results: The great majority were outpatients (n = 125, 88.0%), 52 (36.6%) had migraine with aura, whereas, 90 (63.4%) had migraine without aura. All the patients reporting worsening symptoms progression before COVID-19, had reduced intensity during the lockdown (χ² = 31.05, p < 0.0001). Symptoms frequency reduction was observed in 50% of patients presenting worsening symptoms before the lockdown, 45% of those who were stable, and 12% of those who were already improving. All patients who had resolved symptoms before COVID-19 were stable during the lockdown (χ² = 38.66, p < 0.0001). Anxious symptomatology was significantly associated with greater migraine symptoms frequency (χ² = 19.69, p < 0.001). Repeating the analysis separately for individuals with and without aura did not affect the findings and significant associations were confirmed for both the patients' subgroups.

Discussion: A significant reduction of migraine symptoms intensity and frequency was observed in pediatric patients during the COVID-19 lockdown phase in northern Italy. The improvement in both intensity and frequency of the migraine symptoms was especially significant in patients who were stable or worsening before the lockdown. The reduction of symptoms severity during a period of reduced environmental challenges and pressures further highlights the need of providing effective training in stress regulation and coping for these patients.

Rorschach Evaluation of Personality and Emotional Characteristics in Adolescents With Migraine Versus Epilepsy and Controls

The literature examining primary headache, including migraine, in adolescents, has pointed out the key role played by a wide range of psychiatric disorders in reducing the patients’ quality of life. Moreover, pioneering studies showed that preexisting personality characteristics, specific emotion regulation styles and psychological-psychiatric difficulties are likely to increase the risk of the onset, maintenance, and outcome of headache. Still personality issues in migraine have been poorly studied, in particular in children and adolescents. This study aims, therefore, to investigate the specific characteristics of personality, and in particular emotion regulation and coping strategies, in adolescent with migraine, comparing them with age-matched patients with idiopathic epilepsy and healthy adolescents. 52 adolescents (age: 11–17) were assessed using a multi-method test battery, which included a self-report questionnaire (the youth self-report), a proxy-report (child behavior checklist) along with a projective personality test, the Rorschach Test, administered and scored according to the Exner comprehensive system. The results showed specific personality characteristics in adolescents with migraine, revealing a marked difficulty in modulating and regulating affections through thoughts and reflections, resorting instead to impulsive acts and maladaptive coping strategies, thus revealing a vague and immature perception of reality. Differently from adolescents belonging to the general population, but similarly to patients with epilepsy, adolescents with migraine perceive a high situational stress, probably related to the condition of suffering from chronic disease. They have, therefore, a lower self-consideration and self-esteem along with a poorer insight regarding themselves as well as the relations with others. In line with previous findings, these preliminary results suggest the need for further research on ample samples, using also standardized projective test in order to better understand the pathogenesis of psychological difficulties in patients with migraine. As a clinical implication, the results seem to indicate that providing a psychological integrated approach can play a pivotal role in the assessment and treatment of adolescent with migraine, in order to improve the outcome and the quality of life of the young patients.

Intellectual Profile of Adolescents with Headache: A Case-Control Study Using the WISC-IV

There are few literature evidences about the intellectual profile of adolescents with headache and no study has used the fourth edition of the Wechsler Intelligence Scale for Children (WISC-IV) in patients with a diagnosis of headache according to the ICHD-III-beta. We recruited 30 patients (age 11–14 years; male:female = 1:2) seen for headache in a tertiary center in Northern Italy and 30 healthy controls matched for age and sex, recruited in a public school from the same geographic area. The diagnosis of headache was done according to the ICHD-III criteria (beta version): the case group was composed of 16 patients with migraine and 14 with tension-type headache. Cognitive functioning was assessed using the WISC-IV. Recruited patients with idiopathic headache diagnosis had on average a cognitive function within the normal range. We found no statistically significant differences in the total Intellective Quotient comparing patients with headache and controls; the Working Memory Index was, however, lower in patients with headache (p = 0.012), and in particular, we found a lower Digit Span (p < 0.001). We also found a borderline statistical difference (p = 0.051) between case and controls Verbal Comprehension Index (CVI), which was due to a lower score in the Similarities subtest (p < 0.001). Our results suggest that, although within normal limits, cognitive functioning of adolescents with headache differs from that of healthy peers regarding memory and verbal skills. The Working Memory Index is related to the subject’s ability to store new information and keep them in short-term memory, to maintain focused attention and to manipulate them to find solutions. The difference in Similarities is also important because it provides a measure of the level of verbal reasoning and concept formation; it is also a measure of verbal abstract thinking skills relevant for language development, lexical knowledge, auditory comprehension, memory, and ability to discriminate between essential and non-essential characteristics. Our data, in keep with previous findings, suggest the need for further researches to better understand the pathogenesis of these difficulties and obtain ideas for an adequate rehabilitative treatment.

Comorbidity of Migraine, Major Depressive Disorder, and Generalized Anxiety Disorder in Adolescents and Young Adults

PURPOSE

Depression and anxiety are highly comorbid psychiatric conditions and both are common in adult patients with migraine. This study aims to examine the unique associations between major depressive disorder (MDD) and generalized anxiety disorder (GAD) in a well-characterized group of older adolescents and college-age individuals with migraine.

METHOD

Participants (N =  227), between 15 and 20 years old, who were unmedicated or within 1 month of beginning antidepressant treatment underwent a comprehensive psychiatric assessment to establish the presence of MDD and GAD, according to the Diagnostic and Statistical Manual, Fourth Edition, Text Revision, and to rate their symptom severity using the Longitudinal Interval Follow-up Evaluation for Adolescents (A-LIFE). They then completed the ID-Migraine. The Student's t test and chi-square test were used to compare continuous and categorical variables, respectively, across participants with vs. without migraine. Logistic regression analysis examined the association between the presence of migraine and psychopathology.

RESULTS

A diagnosis of MDD was associated with significantly increased risk of having migraine. Moreover, more severe and persistent ratings of depression were associated with an even higher likelihood of having migraine. A diagnosis of GAD was also significantly associated with the presence of migraine. The prevalence of comorbid MDD and GAD was significantly higher in participants with migraine than those without migraine (55 vs. 22%, p < 0.0001). When examined concurrently, GAD remained significantly associated with migraine, with a statistical trend for MDD to be associated with it.

CONCLUSION

The comorbidity of migraine, MDD, and GAD has important clinical and research implications. Patients who suffer from any of these problems should be screened for all three in order to receive comprehensive care. Shared psychological and biological vulnerabilities may be involved in the three conditions. Greater understanding of the shared vulnerabilities can lead to unified treatments.

Parenting Stress and Emotional/Behavioral Problems in Adolescents with Primary Headache

Primary headache is a frequent and disabling disorder, common among children and adolescents, and it is a painful syndrome often accompanied by functional impairment and associated with emotional and behavior problems. The aim of this study was to investigate parenting stress and emotional/behavioral problems in adolescents affected by primary headache compared with healthy adolescents. The study population consisted of 35 adolescents and a control group of 23 healthy subjects. The assessment included the administration of clinical standardized scales such as Parent Stress Index-Short Form, Pediatric Migraine Disability Assessment Score Questionnaire, and Child Behavior Checklist (CBCL). Headache group and control group did not differ in terms of parenting stress (p = 0.29). On the contrary, headache group showed more internalizing problems (p = 0.023), affective problems (p = 0.01), anxious (p = 0.001), and somatic complaints (p < 0.001) compared with control group. In addition, we found a significant correlation between PSI domains and specific CBCL subscales in the headache group. The findings emphasize the need for expanded intervention in the clinical treatment of pediatric headache, a treatment that may also include the family members. Further research is needed.

Visual-spatial training efficacy in children affected by migraine without aura: a multicenter study

Routinely in the clinical practice, children affected by migraine without aura (MwA) tend to exhibit severe and persistent difficulties within cognitive processes such as attention, memory, and visual-motor integration (VMI) skills. The aim of this study was to assess the visual-spatial and visual-motor abilities among a sample of children with MwA and the effects of a specific computerized training. The study population was composed of 84 patients affected by MwA (39 girls and 45 boys; mean age: 8.91±2.46 years), and they were randomly divided into two groups (group A and group B) comparable for age (P=0.581), gender (P=0.826), socioeconomic status (SES), migraine frequency (P=0.415), and intensity (P=0.323). At baseline (T0), the two groups were comparable for movement assessment battery for children (M-ABC) and VMI performances. After 6 months of treatment (T1), group A showed lower scores in the dexterity item of M-ABC test (P<0.001) and higher scores in M-ABC global performance centile (P<0.001) and total (P<0.001), visual (P=0.017), and motor (P<0.001) tasks of VMI test than group B. Moreover, at T1, group A showed higher scores in total (P<0.001) and motor (P<0.001) tasks of VMI test and in M-ABC global performance centile (P<0.001) and lower scores in the dexterity item of M-ABC test (P<0.001) than at T0. Group B showed, at T1, performances comparable to T0 for all evaluations. As reported by recent studies about alteration MwA among children in motor abilities, our study confirmed these difficulties and the efficacy of a specific software training, suggesting a new rehabilitative proposal in childhood.

Headache in school age

Headache, especially migraine and tension-type headache, is one of the most frequently reported somatic complaints by children and adolescents. Different population-based studies have been conducted to study the correlation between headache and lifestyles in pediatric age, nevertheless, the obtained results are often controversial and these relationship still remain unclear. Likewise, is still strongly debated the burden of headache during school age, its impact on school performances and on quality of life of children and their families. Consequently, larger studies are necessary to evaluate the degree of disability due to pediatric headache. We summarize the ongoing knowledge about these concepts, with the intent to provide useful data to neurologists but also to primary care providers, to further improve the management of pediatric headaches by preventing the headache progression, the disabling effects associated and improving the long-term outcome.

Neurodevelopmental and mental health comorbidities in children and adolescents with epilepsy and migraine: a response to identified research gaps

AIM

To determine the distribution and risk characteristics of comorbid neurodevelopmental and mental health comorbidities among children and adolescents (6-18y) with epilepsy or migraine (i.e. a neurological condition with shared features and potential etiology) compared with lower extremity fracture (LEF).

METHOD

This case-control study involved a subset analysis of surveillance data in South Carolina, USA. Hospital admission, outpatient, and emergency department visits for individuals with an International Classification of Disease, 9th revision Clinical Modification diagnosis of epilepsy (n=6730; 54.5% females, 45.5% males; mean age [SD] 14y 2mo [4y 5mo]); migraine (n=10 495; 74.5% females, 25.5% males; 15y 6mo [2y 6mo]), or LEF (n=15 305; 40.3% females, 59.7% males; 13y 11mo [2y 11mo]) from January 1 2000 to December 31 2011 were identified. The association of epilepsy, migraine, or LEF with any mental health comorbidity was evaluated with univariate and multivariate polytomous logistic regression.

RESULTS

Comorbidities were highly prevalent in children and adolescents, with epilepsy with a rate of 29.7% (95% confidence interval [CI]: 28.6-30.8) for mental health comorbidities and 30.8% (95% CI: 29.7-31.9) for neurodevelopmental comorbidities. The odds of mental health comorbidity was 2.20 (95% CI: 2.02-2.39) for children and adolescents with epilepsy and 1.60 (95% CI: 1.48-1.73) for migraine, in reference to children and adolescents with LEF after adjusting for potential confounders. Prevalence and risk for specific comorbidities are presented.

INTERPRETATION

Neuropathophysiological and psychosocial factors specific to epilepsy may provide more risk for adolescents with epilepsy compared to migraine.

Psychotherapy versus usual care in pediatric migraine and tension-type headache: a single-blind controlled pilot study

Background

Despite growing interest in psychotherapy in child and adolescent headache, efficacy studies in this research field have focused mainly on cognitive-behavioral therapies. Whereas relaxation and cognitive-behavioral techniques, in particular, have been found to reduce the intensity and frequency of headache in children and adolescents, data on psychodynamic psychotherapy in this population are lacking.

Our aim was to explore the effectiveness of a brief psychodynamic psychotherapy program in the treatment of idiopathic headache in childhood and adolescence.

Methods

Thirty-three newly diagnosed idiopathic headache sufferers aged 6–18 years, consecutively referred to our outpatient services, were randomized to receive either a brief cycle of psychodynamic psychotherapy (eight sessions administered at two-week intervals) or usual care (clinical interview, neurological examination, counselling, symptomatic therapy).

The two groups were evaluated at baseline (T0) and at six months (T1) to be assessed for headache characteristics (i.e. frequency, intensity and duration), quality of life (i.e. the EuroQoL score), patient’s global health status (i.e. the Clinical Global Impression score), and emotional-behavioral symptoms (i.e. Child Behavior Checklist scores).

Results

The two groups were fairly similar with reference to the main demographic and clinical variables. The T0/T1 comparison showed a statistically significant improvement in headache frequency (p = 0.005), intensity (p < 0.001) and duration (p = 0.002), a statistically significant improvement in the CGI score (p = 0.018), and a borderline improvement in the EuroQoL score (p = 0.053) in the group receiving psychotherapy.

Conclusions

According to our pilot findings, a brief psychodynamic psychotherapy program may be more effective than usual care in children and adolescents with idiopathic headache.

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).

Migraine and periodic limb movement disorders in sleep in children: a preliminary case-control study

BACKGROUND

The relationships between sleep and headaches are complex and manifold. About the variety of phenomena that can disrupt the sleep macrostructure and can impact its restorative function, the periodic limb movements disorder (PLMd) can be considered as the most powerful.No studies are known about the role of PLMd in the pathophysiology of migraine in children.Aim of study is to assess the prevalence of PLMd and migraine and their relationship with disability and pain intensity in a pediatric sample, referred for migraine without aura by pediatricians.

METHODS

After a preliminary sleep habits screening with the Sleep Disturbances Scale for Children, 34 migraine subjects affected by migraine without aura (20 M, 14 F) (mean age 9.08; SD ± 2.28) and 51 volunteers healthy children (28 M, 23 F) (mean age 9.37; SD ± 1.81) accepted to underwent overnight PSG recordings in the Sleep Laboratory of the Clinic of Child and Adolescent Neuropsychiatry, in order to define the macrostructural sleep characteristics and the prevalence of PLMd. Subsequently, the migraineurs sample was studied in order to define the relationship between disability, pain intensity, therapeutical responsiveness and the presence of PLMd.

RESULTS

In the migraineurs children group, the individuals with PLM pathological index (PLMI ≥ 5) represent the 26.47% of sample and present higher frequency (p < 0.001), intensity (p < 0.001), duration (p = 0.006) and life impairment as scored in the PedMIDAS (p < 0.001) of headache and lower efficacy of prophylactic (p = 0.001) and acute (p = 0.006) pharmacological treatment than MoA children without PLM pathological index.

CONCLUSIONS

This preliminary study indicates the potential value of the determination of the PLMd signs, and the importance of the PSG evaluation in children affected by migraine, particularly when the clinical and pharmacological management tend to fail in the attacks control.

Psychopathological symptoms in child and adolescent migraine and tension-type headache: A meta-analysis

Introduction

After decades of research, the importance of psychological factors in child and adolescent headache is no longer in doubt. However, it is not clearly understood whether different types of headache are comorbid with specific kinds of psychopathology. To address this issue, we set out to establish whether young patients with migraine do or do not show significant levels of psychopathological symptoms compared with age-matched healthy controls and patients with tension-type headache (TTH).

Methods

Ten studies were selected on the basis of a widely used psychodiagnostic tool (the Child Behavior Checklist (CBCL)) and by applying rigorous criteria: The studies were compared in a meta-analysis in order to evaluate the presence of Internalizing (mainly anxiety and depression) and Externalizing (mainly behavioral problems) symptoms in different types of headache (and versus healthy controls).

Findings

Patients with migraine showed more psychopathological symptoms than healthy controls. TTH patients also had more psychopathology than controls, although the difference was more marked in the area of Internalizing disorders. Finally, no differences emerged between migraine and TTH.

Discussion and conclusion

Psychopathological symptoms affect children with migraine, but also children with TTH. Biological, pathophysiological and clinical links need to be established. Effective treatment of affected children and adolescents is imperative in order to prevent chronic evolution. In this context, the CBCL may be a good screening instrument with a view to developing a tailored clinical approach.

Complete corpus callosum agenesis: can it be mild?

Corpus callosum agenesis is a relatively common brain malformation. It can be isolated or included in a complex alteration of brain (or sometimes even whole body) morphology. Etiology and pathogenetic mechanisms have been better understood in recent years due to the availability of more adequate animal models and the relevant progresses in developmental neurosciences. We present the case of a girl with a complete agenesis of the corpus callosum discovered at birth. She had mild learning difficulties, but reached satisfactory levels of autonomy after an individually tailored rehabilitative treatment. Her story is discussed in light of recent findings, which emphasize the possibility to exploit brain plasticity and the utility of an individually tailored approach, defined on the basis of a dialogue with the family and the patient.

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.

Japanese clinical guidelines for chronic pain in children and adolescents

Chronic pain is a common problem in pediatric practice. The prevalence of chronic pain in children is >30%. Because pain indicates emotional expression as well as the physiological reaction toward infection, injury, and inflammation, both physiological and psychological assessments are essential to determine primary interventions for chronic pain. The Japanese Society of Psychosomatic Pediatrics Task Force of clinical practice guidelines for chronic pain in children and adolescents compiled clinical evidence and opinions of specialists associated with the primary care of pediatric chronic pain in the Japanese 'clinical guidelines for chronic pain in children and adolescents' in 2009, which are presented herein. The guidelines consist of three domains: general introduction to chronic pain; chronic abdominal pain; and chronic headache. Each section contains information on the physiological mechanism, psychological aspects, assessment methods, and primary interventions for pediatric chronic pain. These guidelines are expected to help disseminate knowledge on primary interventions for chronic pain in children and adolescents.
