Haemorrhagic strokes confer higher risk of seizures

Cerebrovascular disease is an important cause of epilepsy, particularly in older people. Hospital based studies of seizures after stroke are subject to bias because patients with more severe strokes are more likely to be admitted. The Oxfordshire community stroke project avoids these sources of bias; on page 1582 Burn et al estimate the actuarial and relative risks of epileptic seizures after first stroke. Patients with either a haemorrhagic stroke or total anterior circulation infarction are at higher risk of seizures than other survivors. The 5 year actuarial risk of epilepsy in patients who survive to be independent at 1 month is less than 5%.
