Localized EEG Abnormalities in Acute Carbon Monoxide Poisoning

Arch Neurol. 1981;38(8):524-527. doi:10.1001/archneur.1981.00510080086014
Abstract

• The EEG of a patient with acute carbon monoxide poisoning was characterized by lateralized sharp waves and a focal electrographic seizure discharge within hours of the exposure. These findings were associated with coma and focal motor seizures. The patient made a full clinical recovery, and the EEG was normal two months after the exposure. The association of a primarily diffuse cerebral insult after CO poisoning, with prominent lateralized epileptiform discharges in the EEG, is a distinctly unusual phenomenon.
