Mental and Addictive Disorders and Medical Comorbidities

Mental and addictive disorders commonly co-occur with medical comorbidities, resulting in poor health and functioning, and premature mortality. This review provides an overview of the intertwined causal pathways and shared risk factors that lead to comorbidity. Additionally, this review examines the strategies to prevent the onset of and to effectively manage chronic medical conditions among people with mental and addictive disorders.

Recent research provides further evidence for the shared genetic and biological, behavioral, and environmental risk factors for comorbidity. Additionally, there is evidence of effective approaches for screening, self-management, and treatment of medical conditions among people with mental disorders. There are promising health system models of integrated care, but additional research is needed to fully establish their effectiveness. A combination of public health and clinical approaches are needed to better understand and address comorbidity between mental and addictive disorders and chronic medical conditions.
