Abstract		Monitoring the brain in the neurological ICU can be accomplished with a continuous EEG recording. This monitoring can enhance or supplement ongoing patient assessment with more traditional medical monitoring modalities. Continuous monitoring now can record and display large numbers of EEG channels. EEG tracings can be stored for later review as needed. Trening of EEG frequency in simple ways can provide an uncomplicated method to assess changes over minutes, hours, and days. Remote access to review EEG and trends can be accomplished through networking. Modern digital technology allows for ways to automate the monitoring procedures in ways not available using older techniques such as compressed spectral array (CSA). With these tools, clinicians now can monitor brain functions more closely in neurologically critically ill patients. Such monitoring provides ways to identify previosly undetected noncounvulsive seizures. Trends can detect background variability which correspond well to changes in depth of coma. Focal EEG slowing, loss of variability or other adverse changes can warn of impending complication in time to allow early clinical intervention. Such intervention can help avert serious new problems or neurological sequalae. For example, vasospasm after subarachnoid hemorrhage is a serious impairment. It is often heralded by EEG changes prior to avert clinical deterioration. EEG monitoring can forewarn the clinical team of impending vasospasm even when the patient's clinical examination remains stable. Bedside continuous EEG monitoring is becoming a routine method for monitoring the brain and managing illness in the Neuro-ICU.
