9.Results The latencies of N1,N2,P3 were significantly prolonged in AD and VD group,when compared with normal controls. AD patients had a significant longer P3 latency and lower P3 amplitude than VD patients.
10.Compared with the normal controls, BPD group showed shortened latencies (VEP/P1, P2, AEP/P1, N2), increased amplitudes(VEP/N1- P2,P3,AEP/P3,SEP/P2,P3) and decreased amplitudes(VEP/P2- N2,AEP/P2);
