Visual evoked responses (VERs) were recorded on 52 chronic alcoholics patients without Wernicke-Korsakoff syndrome, 22 of whom had cerebellar ataxia, and eight chronic alcoholics with Wernicke-Korsakoff syndrome. Abnormal VERs were found in 23% of patients without and 37% of patients with Wernicke-Korsakoff syndrome. The main VER abnormalities of all the alcoholic groups were prolonged latency and reduced amplitude of the P100 component. Improvement followed a six month period of abstinence. VERs may be useful in the early detection of alcohol induced brain damage, and in following the progress of patients with the condition.
对52名无韦尼克-科尔萨科夫综合征的慢性酒精中毒患者进行了视觉诱发电位(VERs)记录,其中22人患有小脑共济失调,还有8名患有韦尼克-科尔萨科夫综合征的慢性酒精中毒患者。在无韦尼克-科尔萨科夫综合征的患者中,23%发现VER异常,在患有韦尼克-科尔萨科夫综合征的患者中,这一比例为37%。所有酒精中毒组VER的主要异常表现为P100成分潜伏期延长和波幅降低。戒断六个月后情况有所改善。VERs可能有助于早期发现酒精性脑损伤,并跟踪该病症患者的病情进展。
