Comorbidity Patterns in Alcohol Use Disorder: A Short-Term Residential Program Pilot Study

Alcohol use disorder (AUD) often coexists with psychiatric disorders, complicating treatment and outcome. This pilot study highlights the psychiatric disorders that co-exist with AUD in 403 consecutive admissions to a short-term residential program of the Psychiatric Hospital of Attica, Greece. Clinical and demographic data for these patients were systematically recorded and analyzed. Subsequently, patients diagnosed with at least one other psychiatric disorder were identified and categorized. Notably, approximately 87% of the patients were diagnosed with at least one comorbid psychiatric disorder, with comorbidities reported for Substance Use Disorders, Personality Disorders, Major Depressive Disorder, Anxiety Disorders, Bipolar Disorder, Eating Disorders, and Schizophrenia. The findings indicate that the majority of patients with AUD in this program exhibit at least one additional psychiatric disorder, consistent with trends observed in the international literature.
