Alcohol Use Disorder and Depression: The Complexity of Comorbidity

Abstract

Introduction Alcohol Use Disorder (AUD) and depression are among the most prevalent mental health concerns on a global scale. The co-occurrence of alcohol use disorder (AUD) and depression has been well acknowledged, leading to intricate issues in diagnosis, treatment, and prognosis. Objectives This study aims to analyse the complex correlation between AUD (Alcohol Use Disorder) and depression, with a specific emphasis on examining common underlying causes, reciprocal influences, and potential implications for clinical treatment. Methods An exhaustive review of literature was undertaken, emphasizing epidemiological studies, neurobiological research, and the efficacy of combined treatment modalities. The review also delved into the potential role of genetics, environmental factors, and psychosocial stressors in co-occurrence. Results The available evidence indicates that there exists a reciprocal relationship between depression and alcohol use disorder (AUD), wherein each disease can serve as a triggering factor for the other. This interplay between depression and AUD forms a detrimental cycle that intensifies the severity of both conditions. The comorbidity of various disorders may be attributed to the presence of shared neurochemical pathways, with a particular emphasis on the serotonin system. Furthermore, the co-occurrence of both illnesses frequently leads to heightened symptom severity, reduced treatment efficacy, and a higher risk of suicide. Conclusions The complex relationship between alcohol use disorder (AUD) and depression underscores the need for a comprehensive and integrated therapy strategy. The effective management of this comorbidity necessitates the implementation of multidisciplinary collaboration, patient education, and early intervention. Disclosure of Interest None Declared
