Yes. According to the most recent edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), alcoholism, or alcohol use disorder (AUD), is a diagnosable mental illness that occurs in people who experience at least two of the 11 total criteria for this disorder. In fact, alcohol and mental illness have always been connected. Alcohol use can lead to mental health symptoms, and experiencing mental health distress without treatment can lead people to use alcohol as a way to “cope.”
