Continuous EEG monitoring for the detection of seizures in traumatic brain injury, infarction, and intracerebral hemorrhage: "To detect and protect"

Brain injury results in a primary pathophysiologic response that enables the brain to have seizures. Seizures occur frequently after traumatic and nontraumatic intracerebral bleeding. These seizures can be nonconvulsive, and if one does not monitor for seizures, one will not know they are occurring. The use of continuous EEG monitoring (cEEG) to detect brain arrhythmias after a primary insult, much in way that cardiac arrhythmias are detected after myocardial infarction, can influence treatment decisions and mitigate some of the pathophysiologic natural history of brain injuries. Seizures after brain injury worsen clinical outcome and need to be treated. In summary, cEEG is a valuable clinical instrument "to detect and protect," i.e., to detect seizures and protect the brain from seizure-related injury in critically ill patients, whose brains are often in a particularly vulnerable state.
