Detection of electrographic seizures with continuous EEG monitoring in critically ill patients

American Academy of Neurology | Accepted 26 January 2004

CEEG monitoring detected seizure activity in 19% of patients, and the seizures were almost always nonconvulsive. Coma, age  18 years, a history of epilepsy, and convulsive seizures prior to monitoring were risk factors for electrographic seizures. Comatose patients frequently required  24 hours of monitoring to detect the first electrographic seizure.
