Latency of post-ischemic stroke seizure occurrence since cerebral infarction. a Distribution of seizure onset latency, and b cumulative number of patients. In the early onset group (grey), the first seizure occurred concurrently with stroke (within 24 h) in 77.1 % (37/48) of patients. In the late onset group (black), the latency exhibited a wide variation with a mean of 22.4 months. The peak period was at 6 months to 1 year after stroke
