We studied brainstem auditory, somatosensory and visual evoked potentials in central demyelinating disorders, non demyelinating disorders and control. BAEP studies showed prolonged inter peak latency in demyelinating diseases when compared to non demyelinating diseases. Among those with discernible SSEP waves (N20, P37), no statistically significant differences were seen between the three groups for both latencies as well as amplitudes of waves. The P 100 wave latency in VEP in demyelinating diseases was more prolonged compared to non demyelinating diseases. The findings showed abnormal evoked potentials in both the groups and they help in early and preclinical diagnosis of central nervous system disorders.Keywords
