dual diagnosis
The co-occurrence of a substance use disorder and another mental health disorder in the same individual, requiring integrated treatment approaches.
Full Definition
Dual diagnosis in child and adolescent psychiatry refers to the simultaneous presence of a substance use disorder and at least one other psychiatric condition such as depression, anxiety, ADHD, or conduct disorder. This comorbidity is increasingly common among adolescents and presents significant treatment challenges because each condition can exacerbate the other. Youth with dual diagnoses often require specialized integrated treatment programs that address both conditions simultaneously rather than treating them separately. Treatment planning must consider the complex interactions between substances and mental health symptoms, developmental factors, and the increased risk for treatment dropout and poor outcomes.
Usage
Usage note: Emphasize the need for integrated rather than parallel or sequential treatment approaches.
