dual diagnosis
The co-occurrence of a substance use disorder and a mental health disorder in the same individual requiring integrated treatment.
Full Definition
Dual diagnosis refers to the simultaneous presence of a substance use disorder and a mental health disorder in an individual, requiring specialized integrated treatment approaches that address both conditions concurrently. Common combinations include depression and alcohol use disorder, anxiety disorders with benzodiazepine dependence, or bipolar disorder with stimulant use. Effective dual diagnosis treatment requires clinicians trained in both addiction and mental health, careful medication management, and modified therapeutic approaches that consider the interaction between psychiatric symptoms and substance use. Treatment planning must address how each condition may exacerbate the other and develop strategies for managing both simultaneously.
Usage
Usage note: Preferred term is 'co-occurring disorders' in current clinical practice; 'dual diagnosis' remains common in documentation.
