BIPLEDs in akinetic mutism caused by bilateral anterior cerebral artery infarction

Introduction: Akinetic mutism is described as a result of many disorders. Bilateral infarction of the anterior cerebral artery (ACA) territory is reported rarely, however, often leading to akinetic mutism. Case report: We report a 70 year-old man with akinetic mutism due to bilateral ACA infarction. Electroencephalography, 24 h after admission, showed bilateral independent periodic lateralized epileptiform discharges (BIPLEDs) in the frontal region and diffuse theta and polymorphic delta activity. Discussion: Postanoxic encephalopathy, central nervous system infection and chronic seizure disorders are the major causes of BIPLEDs. However, BIPLEDs may occur in bilateral ACA territory infarction.
