Migraine and behavior in children: influence of maternal headache frequency

The World Health Organization Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders and the headache revolution: from headache burden to a global action plan for headache disorders

The World Health Organization (WHO) Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders was developed by WHO to address the worldwide challenges and gaps in provision of care and services for people with epilepsy and other neurological disorders and to ensure a comprehensive, coordinated response across sectors to the burden of neurologic diseases and to promote brain health across life-course. Headache disorders constitute the second most burdensome of all neurological diseases after stroke, but the first if young and midlife adults are taken into account. Despite the availability of a range of treatments, disability associated with headache disorders, and with migraine, remains very high. In addition, there are inequalities between high-income and low and middle income countries in access to medical care. In line with several brain health initiatives following the WHOiGAP resolution, herein we tailor the main pillars of the action plan to headache disorders: (1) raising policy prioritization and strengthen governance; (2) providing effective, timely and responsive diagnosis, treatment and care; (3) implementing strategies for promotion and prevention; (4) fostering research and innovation and strengthen information systems. Specific targets for future policy actions are proposed. The Global Action Plan triggered a revolution in neurology, not only by increasing public awareness of brain disorders and brain health but also by boosting the number of neurologists in training, raising research funding and making neurology a public health priority for policy makers. Reducing the burden of headache disorders will not only improve the quality of life and wellbeing of people with headache but also reduce the burden of neurological disorders increasing global brain health and, thus, global population health.

The Relationship Between Parental Care and Pain in Children With Headache: A Narrative Review

PURPOSE

In migraine or primary headache in children, parents play a fundamental role in pain management. For this narrative review, PubMed, Google Scholar, and Psych Info were searched using the terms "parent headache", "mother/father headache", "parental impact headache", "alexithymia parents headache", "catastrophizing parent headache", "family headache", "children parent headache", and "quality of life family headache". Articles were chosen for inclusion based on their relevance in to the topic.

OVERVIEW

Several parental and psychological characteristics can influence in children and adolescent headache, such as parental attitudes as oppressive or overprotective; punitive parenting styles; familial psychological symptoms, especially anxiety and depression; catastrophizing about their child's pain or excessive worry about their child's headache; inability to express emotions; and feelings that may lead to somatization problems.

DISCUSSION

Parents' attitudes and behaviors toward their child's headache have a strong relation with the severity of headache attacks. Mothers seem to have more influence than fathers on children's pain and emotional regulation. We suggest that the presence of caregiver-child transmission of maladaptive coping strategies, arising from difficulties expressing emotion, may lead to incorrect management of headache pain, further facilitating headache chronification.

Young People's Response to Parental Neurological Disorder: A Structured Review

Introduction

A significant paucity of literature exists relating to the impact on children of parental neurological disorder, with the exception of multiple sclerosis. The wider literature in this field (parental cancer, depression, alcoholism, HIV/AIDS) exhibits the many potential challenges young people might experience during serious parental illness. Given this, a literature review of parental neurological disorder is long overdue.

Methods

This review is structured around the World Health Organisation (WHO) classification of neurological disorders. The WHO identifies 10 common neurological disorders; dementia, epilepsy, headache, multiple sclerosis, neuroinfections, neurological disorders associated with malnutrition, pain associated with neurological disorders, Parkinson's disease, stroke, and traumatic brain injury. A comprehensive search of the MEDLINE database was performed using key terms for each of the 10 conditions. Results for each condition were divided in to "negative", "positive and/or neutral" and "other" child responses.

Results

The search yielded a total of 6247 titles, of which 184 underwent a full-text assessment. Sixty-five met all eligibility criteria and were thus included in the review. A number of negative issues emerged across parental conditions including the prevalence of child mood disorders, parent-child role reversal, children's need for information on the parental condition, the importance of family cohesion, the negative effect of parental psychopathology and differences between male and female children. A limited number of positive outcomes were evident in a minority of parental conditions. Outcomes measured and methodologies employed were highly heterogeneous.

Conclusion

Children generally respond negatively to parental neurological disorder. Responses varied between neurological disorders, suggesting the need for parental disease-specific guidance and clinical management where required.

Prenatal triptan exposure and neurodevelopmental outcomes in 5-year-old children: Follow-up from the Norwegian Mother and Child Cohort Study

BACKGROUND

Triptans are commonly used to treat migraine headaches, but data on the long-term safety of these medications during pregnancy are sparse. Triptans have a biologically plausible mechanism for effects on the fetal brain through binding to 5-HT₁ -receptors, and previous studies show increased risks of externalising behaviour problems in toddlers exposed to triptans during pregnancy.

METHODS

We included 3784 children in the Norwegian Mother and Child Cohort Study, whose mothers returned the 5-year-questionnaire and reported a history of migraine or triptan use; 353 (9.3%) mothers reported use of triptans during pregnancy, 1509 (39.9%) reported migraine during pregnancy but no triptan use, and 1922 (50.8%) had migraine prior to pregnancy only. We used linear and log-binomial models with inverse probability weights to examine the association between prenatal triptan exposure and internalising and externalising behaviour, communication, and temperament in 5-year-old children.

RESULTS

Triptan-exposed children scored higher on the sociability trait than unexposed children of mothers with migraine (β 1.66, 95% confidence interval [0.30, 3.02]). We found no other differences in temperament, or increased risk of behaviour or communication problems.

CONCLUSIONS

Contrary to results from previous studies in younger children, we found no increased risk of externalising behaviour problems in 5-year-old children exposed to triptans in fetal life. Triptan-exposed children did have slightly more sociable temperaments, but the clinical meaning of this finding is uncertain.

Prevalence of headache and its interference in the activities of daily living in female adolescent students

OBJECTIVE:

To describe the prevalence of headache and its interference in the activities of daily living (ADL) in female adolescent students.

METHODS:

This descriptive cross-sectional study enrolled 228 female adolescents from a public school in the city of Petrolina, Pernambuco, Northeast Brazil, aged ten to 19 years. A self-administered structured questionnaire about socio-demographic characteristics, occurrence of headache and its characteristics was employed. Headaches were classified according to the International Headache Society criteria. The chi-square test was used to verify possible associations, being significant p<0.05.

RESULTS:

After the exclusion of 24 questionnaires that did not met the inclusion criteria, 204 questionnaires were analyzed. The mean age of the adolescents was 14.0±1.4 years. The prevalence of headache was 87.7%. Of the adolescents with headache, 0.5% presented migraine without pure menstrual aura; 6.7%, migraine without aura related to menstruation; 1.6%, non-menstrual migraine without aura; 11.7%, tension-type headache and 79.3%, other headaches. Significant associations were found between pain intensity and the following variables: absenteeism (p=0.001); interference in ADL (p<0.001); medication use (p<0.001); age (p=0.045) and seek for medical care (p<0.022).

CONCLUSIONS:

The prevalence of headache in female adolescents observed in this study was high, with a negative impact in ADL and school attendance.

Offspring of parents with chronic pain: a systematic review and meta-analysis of pain, health, psychological, and family outcomes

Offspring of parents with chronic pain may be at risk for poorer outcomes than offspring of healthy parents. The objective of this research was to provide a comprehensive mixed-methods systematic synthesis of all available research on outcomes in offspring of parents with chronic pain. A systematic search was conducted for published articles in English examining pain, health, psychological, or family outcomes in offspring of parents with chronic pain. Fifty-nine eligible articles were identified (31 population-based, 25 clinical, 3 qualitative), including offspring from birth to adulthood and parents with varying chronic pain diagnoses (eg, mixed pain samples, arthritis). Meta-analysis was used to synthesize the results from population-based and clinical studies, while meta-ethnography was used to synthesize the results of qualitative studies. Increased pain complaints were found in offspring of mothers and of fathers with chronic pain and when both parents had chronic pain. Newborns of mothers with chronic pain were more likely to have adverse birth outcomes, including low birthweight, preterm delivery, caesarian section, intensive care admission, and mortality. Offspring of parents with chronic pain had greater externalizing and internalizing problems and poorer social competence and family outcomes. No significant differences were found on teacher-reported externalizing problems. The meta-ethnography identified 6 key concepts (developing independence, developing compassion, learning about health and coping, missing out, emotional health, and struggles communicating with parents). Across study designs, offspring of parents with chronic pain had poorer outcomes than other offspring, although the meta-ethnography noted some constructive impact of having a parent with chronic pain.

Prenatal triptan exposure and parent-reported early childhood neurodevelopmental outcomes: an application of propensity score calibration to adjust for unmeasured confounding by migraine severity

PURPOSE

Triptan medications are serotonin agonists used to treat migraine, a chronic pain condition highly prevalent in women of reproductive age. Data on the safety of triptans during pregnancy are scant. We sought to quantify the association of prenatal triptan exposure on neurodevelopment in 3-year-old children.

METHODS

Using data from the Norwegian Mother and Child Cohort Study, we used propensity score matching to examine associations between prenatal triptan exposure and psychomotor function, communication, and temperament. We used an external validation study to perform propensity calibration to adjust effect estimates for confounders unmeasured in the main study (migraine severity, type, and maternal attitudes towards medication use).

RESULTS

We identified 4204 women who reported migraine headache at baseline, of which 375 (8.9%) reported using a triptan greater than or equal to once during pregnancy. Children with prenatal triptan exposure had 1.37-fold greater unadjusted odds of fine motor problems (95% confidence interval (CI): 1.06-1.77), which decreased after propensity score matching (odds ratio (OR): 1.29, 95%CI 0.97-1.73) and was further attenuated after calibration (OR: 1.25, 95%CI 0.89-1.74). We observed no increased risk for gross motor or communication problems, and no differences in temperament. Adjustment for migraine severity using propensity score calibration had a moderate impact on effect estimates, with percent changes ranging from 2.4% to 50%.

CONCLUSIONS

Prenatal triptan exposure was not associated with psychomotor function, communication problems, or temperament in 3-year-old children. Adjustment for migraine severity reduced effect estimates and should be considered in future studies of the safety of triptans during pregnancy. Copyright © 2015 John Wiley & Sons, Ltd.

Developmental trajectories of paediatric headache - sex-specific analyses and predictors

BACKGROUND

Headache is the most common pain disorder in children and adolescents and is associated with diverse dysfunctions and psychological symptoms. Several studies evidenced sex-specific differences in headache frequency. Until now no study exists that examined sex-specific patterns of change in paediatric headache across time and included pain-related somatic and (socio-)psychological predictors.

METHOD

Latent Class Growth Analysis (LCGA) was used in order to identify different trajectory classes of headache across four annual time points in a population-based sample (n = 3 227; mean age 11.34 years; 51.2 % girls). In multinomial logistic regression analyses the influence of several predictors on the class membership was examined.

RESULTS

For girls, a four-class model was identified as the best fitting model. While the majority of girls reported no (30.5 %) or moderate headache frequencies (32.5 %) across time, one class with a high level of headache days (20.8 %) and a class with an increasing headache frequency across time (16.2 %) were identified. For boys a two class model with a 'no headache class' (48.6 %) and 'moderate headache class' (51.4 %) showed the best model fit. Regarding logistic regression analyses, migraine and parental headache proved to be stable predictors across sexes. Depression/anxiety was a significant predictor for all pain classes in girls. Life events, dysfunctional stress coping and school burden were also able to differentiate at least between some classes in both sexes.

CONCLUSIONS

The identified trajectories reflect sex-specific differences in paediatric headache, as seen in the number and type of classes extracted. The documented risk factors can deliver ideas for preventive actions and considerations for treatment programmes.

Prenatal Triptan Exposure and Internalising and Externalising Behaviour Problems in 3-Year-Old Children: Results from the Norwegian Mother and Child Cohort Study

BACKGROUND

Triptans are commonly prescribed for migraine, a pain condition that is highly prevalent in women of childbearing age. No prior studies have investigated associations between exposure to triptans during fetal life and risk of externalising and internalising behaviours in children.

METHODS

This study was set in the Norwegian Mother and Child Cohort study, a prospective birth cohort. A total of 41,173 live, singleton births without major malformations present at 36-month post-partum follow-up were included in this study; 396 used a triptan during pregnancy, 798 used a triptan prior to pregnancy only, 3291 reported migraine without triptan use, and 36,688 reported no history of migraine or triptan use. Marginal structural models were used to analyse the association between timing of triptan exposure and neurodevelopmental outcome.

RESULTS

Children exposed to triptans during pregnancy had a 1.39-fold increased risk of externalising behaviours compared with those whose mothers used triptans prior to pregnancy only (95% CI 0.97, 1.97), a 1.36-fold increased risk compared with the unmedicated migraine group (95% CI 1.02, 1.81), and a 1.41-fold increased risk compared with the population comparison group (95% CI 1.08, 1.85). The greatest risk was associated with first trimester exposure (RR 1.77, 95% CI 0.98, 3.14). Risk differences were small, ranging from 3-6%.

CONCLUSIONS

This study found an increased risk of clinically relevant externalising behaviours in children with prenatal exposure to triptans, and this risk was highest for first trimester exposure. Absolute risks were small, and the results may be due to confounding by underlying migraine severity.

Study of various social and demographic variables associated with primary headache disorders in 500 school-going children of central India

Objectives:

This study was performed to know the prevalence of primary headache disorders in school going children of central India and to elucidate the effects of various sociodemographic variables like personality or behavior traits, hobbies like TV watching, school life or study pressure in form of school tests, family history of headache, age, sex, body habitus etc., on prevalence of primary headaches in school going children of central India.

Materials and Methods:

A cross-sectional school-based study was performed on 500 school children (aged 7–14 years) for the duration of 1 year. Potential triggering and aggravating demographic and social variables were investigated based on a diagnosis of International Classification of Headache Disorder-II headache.

Results:

The prevalence of recurrent headache was found to be 25.5% in Indore. Of the studied population, 15.5% had migraine, 5% had tension-type headache migraine, and 5% had mixed-type headache symptoms suggesting both of above. Overall headaches were found to be more common among girls, but tension-type was more common in boys. Using regression analysis, we found that sensitive personality traits (especially vulnerable children), increasing age, female gender and family history of headache had a statistically significant effect on headaches in children. In addition, mathematic or science test dates and post weekend days in school were found to increase the occurrence of headache in school-going children. Hobbies were found to have a significant effects on headaches.

Conclusion:

As a common healthcare problem, headache is prevalent among school children. Various sociodemographic factors are known to trigger or aggravate primary headache disorders of school children. Lifestyle-coping strategies are essential for school children.

Functioning of women with migraine headaches

BACKGROUND

Migraines are one of the most commonly occurring ailments affecting the nervous system. The aim of this research paper was to evaluate the effect migraines have on the everyday functioning of women.

METHOD

The study involved women with diagnosed migraine headaches (IHS-2004) undergoing treatment at a neurological clinic. In order to evaluate the influence of headaches on the everyday functioning of women, a MSQ v.2 questionnaire was used, whereas pain severity was assessed on a linear VAS scale.

RESULTS

Among the clinical factors, the most influential was the frequency of headaches. Headache duration was particularly significant for women below the age of 40. Pain severity cited at 8-10 pts on the VAS significantly disrupted and limited everyday functioning. On the emotional function subscale, the most influential factors were age, education, and the frequency of headaches.

CONCLUSIONS

On account of headache frequency emerging as the most significant influencing factor, it is of the utmost importance to inform patients of the value of taking prophylactic measures. Central to this is the identification of factors that trigger the onset of migraines. This approach would greatly aid the individual in choosing the appropriate treatment, either pharmacological or others.

Pediatric headache: associated psychosocial factors and psychological treatment

All relevant databases (i.e., Pubmed, PsycINFO) were searched for studies published in 2011-2013 focusing on the association of behavioral, cognitive-emotional, and psychosocial factors with recurrent headache in children and adolescents. Only 3 studies were found dealing with psychological intervention for headache; only 2 of them presented empirical data but were not conducted as a RCT. Eleven studies (clinical and population) were concerned with the association of psychosocial factors, dysfunctional psychological traits, and symptoms and headache or examined certain pain features (triggers, course over time, disability). Most studies were interested in the association of cognitive-emotional symptoms (e.g., internalizing symptoms, anxiety) and their relation to headache, including a meta-analysis. In nearly all studies, a close bond between negative affectivity and headache, especially migraine, was revealed.

Functional somatic symptoms in childhood and adolescence

PURPOSE OF REVIEW

Functional somatic symptoms (FSS) are common in children and adolescents, but explanatory models that synthesize research findings are lacking. This article reviews the studies published from January 2012 to March 2013 that investigate the neurophysiological mechanisms that may underlie FSS.

RECENT FINDINGS

Studies from diverse medical disciplines suggest that FSS are associated with functional differences in hypothalamic-pituitary-adrenal function, imbalances in vagal-sympathetic tone, upregulation of immune-inflammatory function, and primed cognitive-emotional responses that serve to amplify reactivity to threatening stimuli, thereby contributing to the subjective experience of somatic symptoms.

SUMMARY

FSS appear to reflect dysregulations of the stress system. When seemingly disparate research findings are interpreted together within an overarching 'stress-system' framework, a coherent explanatory model begins to emerge.
