MENUPost-stroke seizure risk prediction models: a systematic review and meta-analysis Volume 24, numéro 2, April 2022
TEST YOURSELF
(1) How do early post-stroke seizures and late post-stroke seizures differ?
(2) What is the incidence of early post-stroke seizures and late post-stroke seizures, respectively?
(3) What are the commonest risk factors for post-stroke seizures?
Answers
(1) Post-stroke seizures are categorized as early (occurring ≤one week from stroke onset) or late (>one week). The International League Against Epilepsy categorises a single late post-stroke seizure as structural epilepsy due to high risk of recurrence (>60%) within 10 years. Contrastingly, early seizures do not qualify for the diagnosis of post-stroke epilepsy, as aetiologically they are deemed to be provoked.
(2) Among stroke patients, early post-stroke seizure and post-stoke epilepsy incidence rates range from 3.2%-6.3% and 1.3%-14.1%, respectively.
(3) Cortical involvement of stroke lesions, haemorrhage, post-stroke functional deficits, increasing lesion size, and an early post-stroke seizure.
