EEG patterns in each phase of hemiplegic migraine: a systematic review and pooled prevalence meta-analysis.

ABSTRACT:

Introduction

Hemiplegic migraine (HM) is a rare subtype of migraine with aura, and its pathophysiology is similar to that of migraine with aura, primarily involving cortical spreading depression. Electroencephalography (EEG) may serve as a valuable tool for investigating brain function in patients with hemiplegic migraine. Therefore, this study aims to synthesize available evidence through a systematic review and pooled prevalence meta-analysis to assess the types of EEG abnormalities observed in each migraine phase in patients with hemiplegic migraine and to estimate the prevalence of EEG abnormalities during the interictal period.

Method

We searched PubMed, Scopus, and Cochrane up to January 2025 and included articles, including case reports, case series, and retrospective
