Carotid endarterectomy for symptomatic carotid artery stenosis in a patient who presented with psychosis.

Acute psychosis is an unusual presentation of stroke particularly in a patient with no history of psychiatric illness. We report a case where an elderly male patient with self-inflicted injuries caused by acute psychosis. The investigation confirmed an acute left hemispherical stroke associated with a high-grade left internal carotid artery stenosis. The patient underwent a successful left carotid endarterectomy. His psychotic symptoms resolved and he was discharged home without the need for neuroleptic medication.
