co-occurring disorders
The simultaneous presence of mental health and substance use disorders in the same individual.
Full Definition
Co-occurring disorders, also known as dual diagnosis or comorbid disorders, refer to the simultaneous presence of at least one mental health disorder and one substance use disorder in the same individual. This condition requires integrated treatment approaches that address both disorders simultaneously, as they often interact and complicate treatment outcomes. Co-occurring disorders are common, with research indicating that individuals with mental health disorders are at higher risk for substance abuse and vice versa.
