Post stroke late onset Non-convulsive status epilepticus: analysis of 9 cases

INTRODUCTION: Non-convulsive status epilepticus is a condition that needs timely diagnosis and treatment with insignificant clinical features and high risk of misdiagnosis. We aimed to reveal late onset NCSE in patients with stroke where stroke plays a role in the etiology. METHODS: We conducted a retrospective analysis of patients who presented to our outpatient stroke clinic between January 2013 to January 2016. A week after the stroke, patients were defined as late onset NCSE. A total of 9 patients were included. Demographic properties, stroke etiology, imaging modality, EEG findings, stroke severity according to NIHSS score, functional disability, modified Rankin Scale were recorded for all patients. RESULTS: A total of 9 patients were included. The mean age of the study population was 70,5± 9,6 years. There were 8 (88,9%) females, and 1 male. Eight of nine patients had middle cerebral artery, 1 patient had posterior cerebral artery infarct. While 5 patients had cardioembolic stroke, 4 patients had cryptogenic stroke. DISCUSSION AND CONCLUSION: The late onset NCSE after ischemic stroke is not a rare entity. NCSE should be kept in the differential diagnosis of apathy patients with older age and large stroke
