Abstract:
Study examines the usefulness of somatosensory-evoked potentials (SEPs) and cognitive event-related potentials (ERPs) in predicting functional outcomes of patients with severe traumatic brain injury (TBI). Demographic information, SEP and ERP measurements, Glasgow Coma Scale ratings, and functional outcomes as assessed by the Glasgow Outcome Scale-Extended, were obtained for 22 patients with severe TBI. Results showed that bilateral absence of median nerve SEP was strongly predictive of the worst functional outcome, which is death or persistent vegetative state. The presence of normal speech-evoked ERPs was more predictive of the best outcomes than the presence of a normal SEP.
