dual diagnosis
The co-occurrence of a mental health disorder and a substance use disorder in the same individual.
Full Definition
Dual diagnosis, also known as co-occurring disorders, refers to the simultaneous presence of a mental health condition and a substance use disorder. This combination complicates both diagnosis and treatment, as symptoms may overlap or mask each other. Individuals with dual diagnosis often require integrated treatment addressing both conditions simultaneously rather than sequential treatment. Common combinations include depression with alcohol use disorder or bipolar disorder with cocaine use. Treatment planning must consider drug interactions, medication adherence challenges, and the potential for substances to worsen psychiatric symptoms. Specialized dual diagnosis programs provide comprehensive, coordinated care.
Usage
Usage note: Preferred term over 'dual diagnosis' in current practice is 'co-occurring disorders'.
