Alcohol dependence and mood disorders

Abstract

This article explores the complex relationships between alcohol dependence and mood disorders. Although many alcoholics present with substance-induced depressions, once appropriate methodological controls are used, there does not appear to be a significant relationship between independent unipolar depression and alcohol dependence. However, the data support a small, but significant, relationship between bipolar manic-depressive disease and alcoholism. The literature does not support the relevance of self-medication as a course of alcoholism, unless one includes the use of alcohol to alleviate alcohol-induced psychological and neurochemical perturbations. The clinical importance of distinguishing between substance-induced and independent mood disorders is reviewed.
