Chronic alcoholism encephalopathy is a common disease existing all over the world, which is an important symptom of alcohol abuse and alcoholism. In order to promote neurologists’ understanding, popularize the standardized diagnosis and treatment of chronic alcoholism encephalopathy, we have made extensive discussion to reach the following consensus on the principles related to the clinical diagnosis and treatment on chronic alcoholism encephalopathy.I.
