Co-Occurring Disorders

AKA: Dual Diagnosis

When a person has both a substance use disorder and a mental health condition (e.g., depression, anxiety, bipolar disorder, PTSD).

In the context of addiction treatment:
Effective programs treat both conditions at the same time rather than separately.

What to know:

  • Untreated mental health symptoms can increase relapse risk.

  • Many people use substances to self-medicate anxiety, trauma, or mood problems—treating those issues is essential for long-term recovery.
