Is a new formula for assessing levels of consciousness ready for clinical application?
What are the caveats of a system that applies transcranial magnetic stimulation to the brain and records high definition EEG responses? In a study reported in the Aug. 14 Science Translational Medicine, the investigators
compressed the spatiotemporal pattern into a single value, ranging from 0-1, and reported, that using that formula, they were able to reliably differentiate levels of consciousness across a wide group of people — from healthy people during wakefulness, sleep, or under different sedatives; to patients in a locked-in state who can’t move on command but who understand everything; to those who have been diagnosed as minimally conscious; to others in a persistent vegetative state. In a video interview, Neurology Today Editor-in-chief Steven P. Ringel, MD, and Associate Editor Robert Holloway, MD, offer an analysis of the findings.
