Poststroke epilepsy (PSE) occurred in 3.1% of ischemic stroke patients 7-8 years later. A low Scandinavian Stroke Scale (SSS) score on admission predicted PSE risk. Stroke unit care did not impact long-term epilepsy outcomes.

Area of Science:

  • Neurology
  • Epileptology
  • Stroke Medicine

Background:

  • Poststroke epilepsy (PSE) is a significant concern following ischemic stroke.
  • Identifying predictors and long-term outcomes of PSE is crucial for patient management.

Purpose of the Study:

  • To determine the occurrence of poststroke epilepsy (PSE) in ischemic stroke patients.
  • To identify predictors of PSE development.
  • To evaluate the influence of stroke unit (SU) treatment on long-term epilepsy outcomes.

Main Methods:

  • A cohort of 484 ischemic stroke patients was assessed prospectively for 7-8 years.
  • PSE was defined as two or more unprovoked epileptic seizures occurring at least one week after stroke.
  • Predictors were analyzed using multivariate analysis, including Scandinavian Stroke Scale (SSS) scores.

Main Results:

  • PSE developed in 3.1% of patients by 7-8 years post-stroke.
  • A Scandinavian Stroke Scale (SSS) score below 30 on admission was a significant predictor for PSE (OR, 4.9; p = 0.004).
  • Treatment in a stroke unit (SU) versus a general medical ward (GMW), cortical location, or age did not significantly influence PSE risk.

Conclusions:

  • The long-term prevalence of PSE after ischemic stroke is 3.1%.
  • Low admission SSS scores are a key predictor of developing PSE.
  • Stroke unit care does not appear to alter the long-term risk of developing PSE.
