The co-occurrence of a substance use disorder and a mental health disorder is called what?

• A. Dual diagnosis
• B. Harm reduction
• C. Gabapentin
• D. Lapse

Answer: (A)

The concept at play is recognizing when someone has both a substance use disorder and a mental health disorder, which is called dual diagnosis. This label highlights that the two conditions often co-occur and interact, so treatment needs to address both together in an integrated plan. By assessing for mental health symptoms alongside substance use, clinicians can tailor approaches, medications, and therapies to support overall recovery and reduce the risk of relapse.

Harm reduction is a treatment approach aimed at reducing the negative consequences of use, not a label for having two disorders. Gabapentin is a prescription medication used for certain conditions, not a term for co-occurring disorders. A lapse refers to a temporary return to use, not the presence of concurrent mental health and substance use disorders.
