Abstract

The EEG is a very important part of the evaluation of patients with acutely altered mental status. Many of these patients are referred from intensive care settings, and a routine initial step often involves obtaining a 20-min record to screen for seizures, status epilepticus, encephalopathy, or even hypersomnolence. More recently, there has been a move to prolonged monitoring with continuous EEG monitoring (cEEG) also being made available in the intensive care setting with the possibility of remote reviewing of the record.
