Depression is the most common psychiatric problem in people with alcoholism or substance abuse. Estimates of depression in people with alcoholism are as high as 67%. Studies have reported depression accompanies about one-third of all cases of alcoholism. According to a 2000 study, for instance, the risk for heavy drinking in women who are depressed was 2.6 times greater than the risk in women who are not depressed.

Depression is less reported in the male population, but this may be caused by male tendency to mask emotional disorders with behavior such as alcohol abuse.

Specific anxiety disorders, such as panic disorders and social phobia, may pose particular risks for alcohol and substance abuse. Social phobia causes an intense fear of being publicly scrutinized and humiliated. Panic disorders cause intense anxiety and panic attacks. People with these disorders may use alcohol as a way to become less inhibited in public situations or to calm feelings of panic. While anxiety disorders are found in about 15% of all adults, over 50% of people with alcohol abuse problems suffer from these conditions. A 2005 study suggested that people who have anxiety disorders are more likely to resume drinking after treatment for alcohol dependence. [For more information, see In-Depth Report #28: Anxiety.]

Long-term alcoholism itself may cause chemical changes that produce anxiety and depression. In fact, a study on elderly people with depression reported that when even moderate drinkers reduced consumption, their mood improved. It is not always clear, then, whether people with emotional disorders are self-medicating with alcohol, or whether alcohol itself is producing mood swings.

Behavioral Disorders and Lack of Impulse Control. Studies are also finding that alcoholism is strongly related to impulsive, excitable, and novelty-seeking behavior, and such patterns are established early on. Children who later become alcoholics or who abuse drugs are more likely to have less fear of new situations than others, even if there is a greater risk for harm than in nonalcoholics. Specifically, children with attention deficit hyperactivity disorder (ADHD), a condition that shares these behaviors, have a higher risk for alcoholism in adulthood. The risk is especially high in children with ADHD and conduct disorder.
