Anxiety disorders commonly co-occur with substance use disorders. It is known that alcohol-dependent patients are at greater risk of a relapse if they have a comorbid anxiety disorder. There is a lot of literature reporting on the efficacy of treatments that target anxiety or alcohol addiction separately but less research has examined treatments that address these disorders when they co-occur. Anxiety treatment for alcohol-dependent patients with a co-occuring anxiety disorder can alleviate anxiety symptoms but has no significant effect on the outcomes of alcohol treatment. Efficient combinations of psychotherapy and pharmacotherapy can improve outcomes of comorbid disorders.
