The Risk of Seizures Following Stroke

Nearly 5% of patients with ischemic stroke experience a seizure, many within first 24 hours.


 

About 5% of patients who have had an ischemic stroke develop seizures, according to an analysis of data from the Framingham Heart Study. When researchers looked at the incidence of strokes between 1982 and 2003 and followed patients for 20 years, they found strokes had occurred in 469 patients, 25 of whom had experienced a seizure (5.3%). A third of these seizures happened within the first 24 hours of the stroke onset; half occurred within 30 days.
