The ERP changes in alcoholics are discussed with respect to cerebral dysfunction and relapse probability. In addition to the side differences of amplitudes we determined the side differences of latencies. Only in 9 cases there were pathological differences of latencies. Cases of cortical or subcortical lesions , which caused pathological SSEP, were nearly equal frequency. The findings of the investigated sample schowed again that multichannel derivated SSEP can be a suitable toool for demonstrating cerebral dysfunctions even in cases of supratentorial lesions and normal EEG-findings.
Amplitudes seem to be more sensitive than latencies.
