Diagnostic criteria of pediatric migraine without aura

Area of Science:

• Neurology
• Pediatrics
• Headache Medicine

Background:

• Accurate diagnosis of migraine without aura in children is crucial for effective management.
• Existing diagnostic criteria, including International Classification of Headache Disorders-I (ICHD-I) and International Headache Society-Revised (IHS-R), require validation in pediatric populations.
• Features not included in current criteria may aid in diagnosing pediatric migraine without aura.

Purpose of the Study:

• To assess the validity of ICHD-I and IHS-R criteria for diagnosing migraine without aura in children.
• To evaluate additional headache features not covered by current criteria for their diagnostic utility in pediatric migraine without aura.

Main Methods:

• Retrospective analysis of 132 children with chronic or recurrent headaches.
• Clinical diagnosis by a pediatric neurologist served as the gold standard.
• 92 patients with migraine without aura were included after exclusions; ICHD-I and IHS-R criteria validity were assessed against the gold standard.

Main Results:

• The IHS-R criteria demonstrated higher sensitivity (78.7%) and specificity (90.3%) compared to ICHD-I (36.1% sensitivity, 93.5% specificity).
• Resting in a dark, quiet room was identified as a highly sensitive and specific symptom not currently in the criteria.
• Migraine without aura was diagnosed in 66.3% of the final study cohort (61 children).

Conclusions:

• The IHS-R criteria are more valid and recommended for diagnosing migraine without aura in the pediatric population.
• The ICHD-I criteria show lower sensitivity, potentially missing many pediatric cases.
• Incorporating features like seeking a dark, quiet room could improve diagnostic accuracy for pediatric migraine without aura.
