Dual Diagnosis Treatment in Los Angeles
Roughly 50-60% of people with substance use disorders also have a co-occurring mental health condition. Without integrated treatment that addresses both, recovery rates are significantly lower. At Annandale Behavioral Health, dual-diagnosis treatment isn’t an add-on — it’s the foundation of how we treat addiction. Our private 6-bed Pasadena estate is staffed by board-certified addiction psychiatrists, licensed therapists, and an interdisciplinary team trained to treat the addiction and the underlying mental health condition simultaneously.
If you need dual-diagnosis treatment in Los Angeles, call (855) 778-8668 for confidential clinical assessment. PPO accepted.
What is dual diagnosis?
“Dual diagnosis” refers to the simultaneous presence of a substance use disorder and a mental health condition. Common pairings include:
- Alcohol use disorder + depression or anxiety — most common dual diagnosis. Alcohol is often used to self-medicate underlying mood symptoms.
- Opioid use disorder + chronic pain or PTSD — opioids relieve both physical and emotional pain temporarily.
- Stimulant use disorder + ADHD — what begins as performance enhancement progresses to dependence.
- Alcohol/drug use + bipolar disorder — substance use during manic and depressive phases is exceptionally common.
- Polysubstance use + complex PTSD — trauma-driven addiction requires trauma-informed care.
- Substance use + eating disorders — frequently overlap, particularly in young adult women.
- Substance use + personality disorders — borderline, narcissistic, and avoidant personality traits often complicate treatment.
Why integrated treatment matters
For decades, addiction treatment and mental health treatment were delivered in separate systems by separate providers — a structural failure that left dual-diagnosis patients underserved. Research has now established beyond doubt: integrated dual-diagnosis treatment produces dramatically better outcomes than sequential or parallel treatment.
When mental health symptoms are untreated, relapse rates climb. When substance use continues, mental health treatment is undermined. Treating both at the same time, with the same team, in the same setting, is the standard of care.
Annandale’s dual-diagnosis approach
Comprehensive psychiatric evaluation at intake
Every patient receives a full psychiatric assessment within 48 hours of admission, conducted by a board-certified addiction psychiatrist. This includes diagnostic interview, review of prior treatment, medication history, family history, and trauma history. Where appropriate, we use validated screening instruments (PHQ-9 for depression, GAD-7 for anxiety, PCL-5 for PTSD).
Medication management throughout treatment
Our psychiatrist manages psychotropic medications during residential care: antidepressants (SSRIs, SNRIs, atypicals), mood stabilizers (lamotrigine, lithium), anti-anxiety (non-addictive alternatives to benzodiazepines), antipsychotics where indicated, and ADHD medications (non-stimulant preferred during recovery). Medication is one tool among many — never the only tool.
Trauma-informed therapy
The majority of patients with substance use disorders have trauma history. Our clinical team is trained in evidence-based trauma modalities including EMDR, Cognitive Processing Therapy (CPT), Prolonged Exposure (PE), Somatic Experiencing, and trauma-focused CBT. Trauma work begins when patients are clinically stable — typically several weeks into residential care.
Specialized programming for specific co-occurring conditions
Within our 6-bed model, we tailor programming to each patient’s dual diagnosis. A patient with bipolar disorder and alcohol use receives different therapy emphasis than a patient with ADHD and stimulant addiction.

Frequently asked questions
How is dual diagnosis different from “regular” rehab?
Regular rehab focuses on the addiction. Dual diagnosis treats the addiction AND the underlying mental health condition simultaneously, with integrated staff and protocols. For patients with mental health comorbidity, dual diagnosis is not optional — it’s the difference between recovery and relapse.
Do I have to be diagnosed with a mental illness to get dual-diagnosis care?
No. Many patients arrive at Annandale without a formal mental health diagnosis but with clear symptoms. Our intake assessment identifies what’s clinically present and what needs treatment.
What if I’m worried about psychiatric medication?
Medication is one tool among many. Many patients recover without medication. Others find appropriate, non-addictive psychiatric medication essential. The decision is collaborative and based on clinical evidence, not blanket policy.
Is dual-diagnosis treatment confidential?
Yes. Both addiction and mental health information is protected. We do not share patient information without explicit written consent.
