Clinico-neurophysiological correlations in chronic alcoholic Korsakoff patients.

: A group of 29 patients with chronic alcoholic KORSAKOFF syndrome (KS) showed a cumulative increase in the interpeak latencies (IPL)I-II to I-VII of the brainstem auditory evoked potentials (BAEP), highest significance with IPL I-VI (p = 7.27 X 10(-6). The KORSAKOFF core group showed higher multiple correlation coefficients R for the IPL than the KS with additional deficiencies of cerebral performance. The BAEP should be used for recording subclinical patterns of brainstem lesions in risk patients with chronic alcoholism.
