Abstract TP341: Risk Factors of Seizure Recurrence in First-ever Post-stroke Seizure

Background: Both early seizure (ES) and late seizure (LS) are common complications after stroke. However, clinical characteristics, treatments and recurrences after ES/LS remain unclarified. Methods: We enrolled the patients with first-ever post-stroke seizures between July 2010 and June 2014, and followed up until June 2015. Seizures were classified into ES (within one week after stroke) and LS (the second week or later). We compared baseline clinical characteristics, status epilepticus, surgery (removal of hematoma, ventricular drainage), neurological deterioration by index stroke (defined as an increase of the NIHSS score by one or more between the baseline and at hospital discharge), and duration of antiepileptic drug (AED) therapy between two groups. We also investigated factors (patients’ background and treatment of seizure) that determined the seizure recurrence after discharge. Results: Clinical data were collected for 153 patients (82 men; age, 73.7±12.3, 73 intracerebral hemorrhage and 80 ischem...
