Risk of ischaemic stroke in people with migraine: systematic review and meta-analysis of observational studies.

ABSTRACT:

Objective

To explore the association between migraine and risk of ischaemic stroke.

Design

Systematic review and meta-analysis.

Data sources

Observational studies published between 1966 and June 2004 (identified through Medline and Embase) that examined the association between migraine and risk of ischaemic stroke.

Results

14 studies (11 case-control studies and 3 cohort studies) were identified. These studies suggest that the risk of stroke is increased in people with migraine (relative risk 2.16, 95% confidence interval 1.89 to 2.48). This increase in risk was consistent in people who had migraine with aura (relative risk 2.27, 1.61 to 3.19) and migraine without aura (relative risk 1.83, 1.06 to 3.15), as well as in those taking oral contraceptives (relative
