Event related evoked potentials in hypertensive subjects.
Cognitive functions were assessed in hypertensive and sex and age matched healthy controls using auditory event related evoked potential 'odd ball' paradigm. The N2 and P3 latencies in the hypertensive subjects were significantly delayed as compared to controls. There was also correlation of blood pressure (BP) with N2 latency in hypertensive group. These findings suggest that cortical neurophysiological events, depicting information processing and memory are modulated by rise in BP and cognition is delayed in hypertensive cases.
