Standardized Approach to Grading Level of Brain Dysfunction on EEG

The widespread use of prolonged electroencephalogram (EEG) in critically ill patients has revealed its additional utility as a continuous monitoring tool for the detection of focal and global brain dysfunction, ischemia detection, and in neuroprognostication. Significant variation exists in the interpretation of the degree of dysfunction on EEG, as no standardized method has been widely adopted. In this lecture, Dr. Carolina Maciel from the University of Florida College of Medicine, will present a streamlined 5-category scale, excluding normal and complete suppression, that incorporates the background frequencies, PDR, continuity when most awake, reactivity and state changes.
