Short-latency EPs (brainstem auditory evoked potentials, pattern visual evoked potentials, brainstem trigeminal nerve stimulation, motor evoked potentials, and somatosensory evoked potentials) have been used to investigate mild TBI as well as the postconcussive syndrome and individual postconcussive symptoms (e.g., dizziness, cognitive impairment). Many of these studies identify short-latency EP abnormalities similar to those observed in more severely injured individuals. Such abnormalities are identified in approximately 10%–30% of persons with mild TBI.
