Migraine & paediatric obesity: a plausible link?

Area of Science:

• Neurology
• Endocrinology
• Public Health

Background:

• Obesity and migraine are prevalent disorders with shared genetic and environmental risk factors.
• Obesity is increasingly recognized as a significant risk factor for transformed migraine, associated with increased headache frequency and disability.
• Both conditions frequently co-occur with psychiatric comorbidities like depression and anxiety, exacerbating symptoms.

Purpose of the Study:

• To explore the impact of obesity on migraine prevalence and outcomes.
• To investigate the underlying biological mechanisms linking obesity and migraine.
• To emphasize the importance of weight assessment and management in migraine treatment.

Main Methods:

• Literature review of recent studies on obesity and migraine.
• Analysis of proposed pathophysiological mechanisms connecting obesity and migraine.
• Clinical recommendation for weight and BMI measurement in migraine patients.

Main Results:

• Obesity is a strong risk factor for transformed migraine and is linked to more frequent headaches and higher disability scores in migraineurs.
• Potential mechanisms include obesity-induced inflammation, elevated calcitonin gene-related peptide (CGRP) levels, orexin dysmodulation, and altered leptin/adiponectin signaling.
• Psychiatric comorbidities like depression and anxiety are associated with both conditions, worsening headache frequency and disability.

Conclusions:

• Obesity significantly impacts migraine outcomes, increasing headache frequency and disability.
• Understanding the pathophysiological links, including inflammatory and neuroendocrine pathways, is crucial.
• Weight and BMI assessment, alongside weight control strategies, should be integral to migraine management, particularly in pediatric populations.
