Non-Convulsive Status Epileptics Presenting with Periodic Lateralized Epileptiform Discharges and Coma after Cerebral Hemorrhage: A Case Report

Background: Non-convulsive status epileptics (NCSE) is a common neurological emergency necessitating rapid assessment and management, but is often underdiagnosed as it lacks specific electroencephalographic features. The diagnostic value of periodic lateralized epileptiform discharges (PLEDs) in NCSE is still unclear. Herein, we reported a case with NCSE manifesting as PLEDs and coma. Case Report: A 62-year-old man presented with epileptic seizures. Based on clinical and radiological profiles, he was diagnosed with frontal hemorrhage, coma, and NCSE. An electroencephalogram (EEG) revealed PLEDs. A combined antiepileptic regimen was initiated and, over a follow-up period of 2 months, a favorable outcome was achieved. Conclusion: EEG may help identify potential NCSE in comatose patients, and PLEDs can be an atypical manifestation of NCSE, which can be effectively treated with antiepileptic drugs. The emphasis in NCSE is on early identification and individualized therapeutic regimens.
