Examined whether auditory and visual P300, using a dense array of scalp electrodes, could be a tool for demonstrating cognitive disturbances in 8 apparently normal, closed head injury (CHI) patients (aged 32-63 yrs) with mild cognitive complaints. 32 normal Ss (aged 26-64 yrs) served as controls. 75% of Ss with mild CHI, normal neurological exam, and complaints of impaired alertness and mild cognitive difficulties, had abnormally long visual P300 latencies.
