Visual evoked potentials in the older population: age and gender effects

Pattern reversal visual evoked potentials (VEPs) were elicited from 68 normal subjects (31 males, 37 females) in the age range 40-80 years. With VEP latency, a significant age effect, increasing values with age, was demonstrated, but none in relation to gender. The converse held true for VEP amplitude however, no age effect being observed, but some gender effect in that lower values were elicited from males as compared to females.
