Abstract
Migraine and hemorrhagic stroke: data from general practice.
Highlights
Migraine is one of the most disabling headache disorders and the seventh most disabling disease worldwide [1]
The case–control study published in The Journal of Headache and Pain by Gaist and colleagues [6] adds important data gathered from general practice to the link between migraine and vascular diseases
Analysis according to migraine type showed that neither migraine with aura (MA) nor migraine without aura (MO) were associated with an increased risk of hemorrhagic stroke (HS), intracerebral hemorrhage (ICH) or subarachnoid hemorrhage (SAH) [6]
Summary
Migraine is one of the most disabling headache disorders and the seventh most disabling disease worldwide [1]. Data from 1,797 subjects with ICH and 1,340 subjects with SAH from a large epidemiological dataset, The Health Improvement Network (THIN), were reviewed and frequency-matched with control subjects for sex, age (±1 year), and calendar year of diagnosis. After adjustment for sex, age, calendar year, smoking, alcohol, body mass index, hypertension, previous cerebrovascular disease, oral contraceptive use, and health services utilization, the authors did not find an increased risk of overall HS or of ICH or SAH in subjects with migraine compared with non-migraineurs.
