Why are alcohol and depression so commonly linked?

Does Alcohol Cause Depression?

Recent studies suggest that while depression may lead to increased alcohol abuse, the reverse is actually more common [source: Anderson]. The 1996 U.S. National Comorbidity Survey found that nearly one in three respondents who had alcohol dependence also had a mood disorder such as major depression, and those with alcohol dependence were almost four times more likely to have had a major depressive disorder in the year prior to the survey [source: Petrakis].

This may occur because alcohol alters the way certain neurotransmitters work in the brain [source: Anderson]. But researchers say it's more likely that alcohol abuse simply wreaks havoc in one's life, and the fallout -- losing one's job, relationship troubles, legal problems -- prompts depressive episodes.

Let's say, without previous symptoms of depression, you began drinking to excess twice every week. That would mean two nights of poor sleep, and two days of feeling physically ill due to a hangover, as well as anxious or guilty feelings resulting from alcohol-related dysphoria. Perhaps your alcohol abuse creates financial insecurity, as a result of poor decisions you've made while under the influence, along with legal troubles, such as a D.W.I. offense. When abusing alcohol, you're more likely to hurt yourself, and you might also experience diminished cardiovascular health, poor diet and low energy. Friendships and relationships may be damaged, your reputation harmed. After a year of this, the results of those twice-weekly bouts of heavy drinking would practically double as the symptoms of depression.

In these cases, treating alcohol abuse or dependence might also effectively treat depression -- or, rather, it would eliminate the need to treat depression because the underlying cause -- alcohol abuse -- would no longer exist [source: Anderson].

However, the reverse isn't necessarily true. In other words, treating major depression may not affect problems with alcohol abuse.

Some patients might try taking a selective serotonin reuptake inhibitor (SSRI), such as sertraline, which in some cases serves as an effective pharmaceutical treatment for both depression and alcohol abuse [source: Misra]. For others, counseling alone -- or participation in a 12-step program like Alcoholics Anonymous (AA) -- may be the best option. For many, some mix of ongoing counseling and medication is most effective.
