Abstract
P-300 wave was recorded using auditory stimuli in 15 patients presenting with post concussion vertigo. The mean latency of the normal P300 recordings was 316.5 msec while that of the delayed recordings was 392.3 msec. 6 Patients had a bilateral and 4 had an unilateral delay in latency. 5 patients had normal latency bilaterally. The severity of symptoms was directly proportinoal to the delay in latency. This pilot study, though suggestive of a correlation between P300 wave and vertigo is inconclusive because of the limited number of patients studied.
