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.
