Migraine and lifestyle in childhood

Unveiling new insights into migraine risk stratification using machine learning models of adjustable risk factors

BACKGROUND

Migraine ranks as the second-leading cause of global neurological disability, affecting approximately 1.1 billion individuals worldwide with severe quality-of-life impairments. Although adjustable risk factors-including environmental exposures, sleep disturbances, and dietary patterns-are increasingly implicated in pathogenesis of migraine, their causal roles remain insufficiently characterized, and the integration of multimodal evidence lags behind epidemiological needs.

METHODS

We developed a three-step analytical framework combining causal inference, predictive modeling, and burden projection to systematically evaluate modifiable factors associated with migraine. First, two-sample mendelian randomization (MR) assessed causality between five domains (metabolic profiles, body composition, cardiovascular markers, behavioral traits, and psychological states) and the risk of migraine. Second, we trained ensemble machine learning (ML) algorithms that incorporated these factors, with Shapley Additive exPlanations (SHAP) value analysis quantifying predictor importance. Finally, spatiotemporal burden mapping synthesized global incidence, prevalence, and disability-adjusted life years (DALYs) data to project region-specific risk and burden trajectories through 2050.

RESULTS

MR analyses identified significant causal associations between multiple adjustable factors (including overweight, obesity class 2, type 2 diabetes [T2DM], hip circumference [HC], body mass index [BMI], myocardial infarction, and feeling miserable) and the risk of migraine (P < 0.05, FDR-q < 0.05). The Random Forest (RF)-based model achieved excellent discrimination (Area under receiver operating characteristic curve [AUROC] = 0.927), identifying gender, age, HC, waist circumference [WC], BMI, and systolic blood pressure [SBP] as the predictors. Burden mapping projected a global decline in migraine incidence by 2050, yet persistently high prevalence and DALYs burdens underscored the urgency of timely interventions to maximize health gains.

CONCLUSIONS

Integrating causal inference, predictive modeling, and burden projection, this study establishes hierarchical evidence for adjustable migraine determinants and translates findings into scalable prevention frameworks. These findings bridge the gap between biological mechanisms, clinical practice, and public health policy, providing a tripartite framework that harmonizes causal inference, individualized risk prediction, and global burden mapping for migraine prevention.

Tools for Evaluating the Quality of Life of the Paediatric Population with Primary Headaches-A Review of Selected Questionnaires

Primary headaches are a common health issue in the paediatric population. These conditions have a negative impact on the quality of life of patients at the development age in every area of their lives. The aim of this study is to list the tools used to evaluate the quality of life of the paediatric population with primary headaches and to discuss their advantages and limitations. Examining the quality of life of children and adolescents suffering from primary headaches is of particular importance. This is a consequence of a high disease incidence rate and a considerable negative impact of the ailment on the everyday life of this population. It is very important to conduct such examinations with specific and validated tools. It is significant because of the particular features of the areas of patients' lives at the developmental age. Each of the available questionnaires has specific characteristics, advantages and limitations. The data accumulated in this literature review can be of help in designing research on the quality of life of children and adolescents suffering from primary headaches.

Early alterations of cortical thickness and gyrification in migraine without aura: a retrospective MRI study in pediatric patients

Background

Migraine is the most common neurological disease, with high social-economical burden. Although there is growing evidence of brain structural and functional abnormalities in patients with migraine, few studies have been conducted on children and no studies investigating cortical gyrification have been conducted on pediatric patients affected by migraine without aura.

Methods

Seventy-two pediatric patients affected by migraine without aura and eighty-two controls aged between 6 and 18 were retrospectively recruited with the following inclusion criteria: MRI exam showing no morphological or signal abnormalities, no systemic comorbidities, no abnormal neurological examination. Cortical thickness (CT) and local gyrification index (LGI) were obtained through a dedicated algorithm, consisting of a combination of voxel-based and surface-based morphometric techniques. The statistical analysis was performed separately on CT and LGI between: patients and controls; subgroups of controls and subgroups of patients.

Results

Patients showed a decreased LGI in the left superior parietal lobule and in the supramarginal gyrus, compared to controls. Female patients presented a decreased LGI in the right superior, middle and transverse temporal gyri, right postcentral gyrus and supramarginal gyrus compared to male patients. Compared to migraine patients younger than 12 years, the ≥ 12-year-old subjects showed a decreased CT in the superior and middle frontal gyri, pre- and post-central cortex, paracentral lobule, superior and transverse temporal gyri, supramarginal gyrus and posterior insula. Migraine patients experiencing nausea and/or vomiting during headache attacks presented an increased CT in the pars opercularis of the left inferior frontal gyrus.

Conclusions

Differences in CT and LGI in patients affected by migraine without aura may suggest the presence of congenital and acquired abnormalities in migraine and that migraine might represent a vast spectrum of different entities. In particular, ≥ 12-year-old pediatric patients showed a decreased CT in areas related to the executive function and nociceptive networks compared to younger patients, while female patients compared to males showed a decreased CT of the auditory cortex compared to males. Therefore, early and tailored therapies are paramount to obtain migraine control, prevent cerebral reduction of cortical thickness and preserve executive function and nociception networks to ensure a high quality of life.

Diagnosis and Management of Headaches in the Emergency Department (ED) in Adults and Children

Background

Headache accounts for a significant number of cases presenting to the Emergency Department (ED) and has a high societal cost, contributed by recurrent ED and clinic visits, and unnecessary diagnostic tests.

Objective

This review article covers the important clinical tools needed to evaluate headaches in both adults and children in the ED.

Methods

Medline/PubMed was searched using the keywords "Emergency department", "headache", "adult", "pediatric", "clinical assessment", "diagnosis" and "treatment", in the title or abstract. The search covers the period from 1 January 1990 to 31 December 2019.

Results

The articles selected were based on their relevancy to the objective of this review article. Additional relevant publications were identified from article references lists.

Conclusion

The emergency physician plays a key role in differentiating between primary and secondary headaches. Within the limited ED resources, appropriate diagnostic testing should be used to identify the life-threatening headaches. This will ensure patients are given the appropriate evidence-based pharmacological therapy and holistic management.

Lifestyle Modifications to Help Prevent Headache at a Developmental Age

Headache is the world's seventh most significant cause of disability-adjusted-life in people aged between 10 and 14 years. Therapeutic management is based on pharmacological approaches and lifestyle recommendations. Many studies show associations between each migraine-promoting lifestyle, behavioral triggers, frequency, and intensity of headaches. Nevertheless, the overall aspects of this topic lack any definitive evidence. Educational programs advise that pediatric patients who suffer from migraines follow a correct lifestyle and that this is of the utmost importance in childhood, as it will improve quality of life and assist adult patients in avoiding headache chronicity, increasing general well-being. These data are important due to the scarcity of scientific evidence on drug therapy for prophylaxis during the developmental age. The "lifestyle recommendations" described in the literature include a perfect balance between regular sleep and meal, adequate hydration, limited consumption of caffeine, tobacco, and alcohol, regular physical activity to avoid being overweight as well as any other elements causing stress. The ketogenic diet is a possible new therapeutic strategy for the control of headache in adults, however, the possible role of dietary factors requires more specific studies among children and adolescents. Educational programs advise that the improvement of lifestyle as a central element in the management of pediatric headache will be of particular importance in the future to improve the quality of life of these patients and reduce the severity of cephalalgic episodes and increase their well-being in adulthood. The present review highlights how changes in different aspects of daily life may determine significant improvements in the management of headaches in people of developmental age.

Experts' opinion about the primary headache diagnostic criteria of the ICHD-3rd edition beta in children and adolescents

BACKGROUND

The 2013 International Classification of Headache Disorders-3 (ICHD-3) was published in a beta version to allow the clinicians to confirm the validity of the criteria or to suggest improvements based on field studies. The aim of this work was to review the Primary Headache Disorders Section of ICHD-3 beta data on children and adolescents (age 0-18 years), and to suggest changes, additions, and amendments.

METHODS

Several experts in childhood headache across the world applied different aspects of ICHD-3 beta in their normal clinical practice. Based on their personal experience and the literature available on pediatric headache, they made observations and proposed suggestions for the primary headache disorders section of ICHD-3 beta data on children and adolescents.

RESULTS

Some headache disorders in children have specific features which are different from those seen in adults and which should be acknowledged and considered. Some features in children were found to be age-dependent: clinical characteristics, risks factors and etiologies have a strong bio psycho-social basis in children and adolescents making primary headache disorders in children distinct from those in adults.

CONCLUSIONS

Several recommendations are presented in order to make ICHD-3 more appropriate for use with children.

Lifestyle Factors and Migraine in Childhood

Migraine is one of the most common pain symptoms in children. Indeed, a high percentage of adult migraine patients report to have suffered from recurrent headache during the childhood. In particular, children could experience the so-called childhood periodic syndromes (such as cyclic vomiting, abdominal migraine, and benign paroxysmal vertigo) that have been usually considered precursors of migraine or they could develop overt migraine headaches. However, typical cohort of migraine symptoms could be absent and children could not achieve all clinical features necessary for a migraine attack diagnosis according to classification criteria. Nevertheless, migraine is characterized also in childhood by a significant negative impact on the quality of life and a high risk of developing chronic and persistent headache in adulthood. Several studies have emphasized the role of different risk factors for migraine in children. Among these, obesity and overweight, particular food or the regular consumption of alcohol or caffeine, dysfunctional family situation, low level of physical activity, physical or emotional abuse, bullying by peers, unfair treatment in school, and insufficient leisure time seem to be strictly related to migraine onset or progression. Consequently, both identification and avoidance of triggers seem to be mandatory in children with migraine and could represent an alternative approach to the treatment of migraine abstaining from pharmacologic therapies.
