The current status of electrophysiologic procedures for the assessment of mild traumatic brain injury

Design: This review examines studies that used spontaneous electroencephalo graphy (EEG), evoked potentials (EP), event-related potentials (ERP), and m agnetoencephalography (MEG) to detect brain dysfunction in mild traumatic b rain injured (MTBI) subjects. Conclusions: The following conclusions are of fered: (1) standard clinical EEG is not useful: however, newer analytical p rocedures may be proven valuable; (2) consistent with current theory of MTB I, cognitive ERPs seem to be more sensitive to injury than EPs: (3) develop ment of an assessment battery that may include EEG. EPs. ERPs, and neuropsy chologic testing is advocated.
