(1994). Reversibility of brain-stem evoked potential abnormalities in abstinent chronic alcoholics: one year follow-up. Electroencephalography and clinical neurophysiology, 90(6), 450–4550013-4694http://hdl.handle.net/10347/24442Brain-stem auditory evoked potentials (BAEPs) were studied in 34 chronic alcoholics who had been abstinent for 1 year, and in age- and sex-matched control subjects. The patients were examined 3 times, at 1 month, 5 months and 1 year after the start of the abstinence treatment. At 1 month of abstinence the alcoholics showed differences with respect to controls in the peak V latency (P < 0.01), and in the III–V (p < 0.01) and I–V (p < 0.01) intervals. After 1 year of abstinence a significant improvement in the V (p < 0.01), III–V (p < 0.01) and I–V (p < 0.01) parameters was recorded. The most notable development was in the 5–12 month period, with shortening i latency (p < 0.01) and in the I–V interval (p < 0.01); in the first 5 months there was only shortening in the III–V interval (p < 0.01). This improvement was also indicated by a decrease in the number of patients with BAEP parameter abnormalities. The recovery of the functions impaired by chronic alcohol consumption after 1 year of abstinence was incomplete, although the tendency was towards normalizationengCopyright © 1994 Published by Elsevier Ireland Ltd.
