Dual Diagnosis Treatment Centers: Understanding Co-Occurring Disorders
A dual diagnosis—also called co-occurring disorders—means a person is experiencing both a mental health disorder and a substance use disorder (SUD) at the same time. These conditions frequently overlap and often make each other worse. Someone may develop depression after long-term alcohol use, or a person with untreated anxiety may use drugs to self-medicate.
Because the disorders reinforce one another, treating only one condition leads to poor outcomes and higher relapse rates. Effective recovery requires integrated, simultaneous treatment for both conditions.
Common Dual Diagnosis Conditions
Any mental health disorder can appear alongside addiction, but the most frequently diagnosed combinations include:
Many individuals turn to alcohol or drugs to manage emotional pain or distress—a pattern known as self-medication. Although substances may offer temporary relief, they ultimately worsen mental health symptoms and increase the risk of dependency.
How Co-Occurring Disorders Are Diagnosed
A dual diagnosis must be confirmed by a trained clinician using guidelines from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Diagnosis typically includes:
Substance Use Disorder (SUD) A SUD is identified when someone continues using a substance despite negative consequences affecting health, behavior, relationships, or responsibilities.
Mental Health Disorder Mental illnesses affect emotion regulation, behavior, thinking, and the ability to function in daily life.
A diagnosis is made when symptoms cause significant impairment in social, occupational, or emotional functioning.
According to national data, more than 17 million U.S. adults have both a mental illness and a substance use disorder.

Why Do Co-Occurring Disorders Happen?
Researchers have identified three major pathways that explain why dual diagnoses occur:
- Shared Risk Factors Mental illnesses and SUDs often share similar genetic, biological, and environmental risk factors. Trauma, chronic stress, and family history increase susceptibility to both.
- Self-Medication Someone with depression, anxiety, or PTSD may use substances to numb emotional pain. This provides short-term relief but worsens symptoms over time.
- Substance-Induced Mental Health Changes Drugs and alcohol can alter brain chemistry, impair emotional regulation, and increase the likelihood of developing a mental health disorder.
Symptoms of Co-Occurring Disorders
Only a licensed professional can diagnose dual disorders, but recognizing signs can help you seek treatment sooner.
Symptoms of a Substance Use Disorder (DSM-5 criteria) include:
- Strong cravings for alcohol or drugs
- Using more than intended
- Failed attempts to cut down
- Using in dangerous situations (e.g., driving)
- Neglecting responsibilities
- Social or relationship issues
- Loss of hobbies
- Spending large amounts of time using or recovering
- Continued use despite worsening health
- Tolerance (needing more)
- Withdrawal symptoms
Symptoms of a Mental Health Disorder
- Extreme or persistent sadness
- Anxiety or panic attacks
- Impulsive or risky behavior
- Difficulty concentrating
- Emotional instability
- Delusions or hallucinations
- Suicidal thoughts
- Inability to function in daily life
If you or a loved one shows symptoms of both, dual diagnosis treatment is essential.
Causes and Risk Factors for Dual Diagnosis
Common shared risk factors include:
- Genetics: Up to 40–60% of vulnerability to addiction is genetic. Mental illnesses and SUDs both tend to run in families.
- Life Experiences: Childhood trauma, early exposure to drugs, violence, or chronic stress significantly increases the likelihood of co-occurring disorders.
- Brain Chemistry: Dopamine, serotonin, GABA, and brain regions tied to emotion, reward, and decision-making play major roles in both conditions.
Dual Diagnosis Treatment Options
The gold standard for recovery is integrated treatment, where both disorders are treated at the same time by the same clinical team. Treating one disorder while ignoring the other increases relapse risk and decreases long-term success.
Levels of Care Include:
- Inpatient Dual Diagnosis Treatment 24/7 supervised care, best for severe symptoms or unsafe living environments.
- Partial Hospitalization Program (PHP) Full-day programming 5–7 days weekly; ideal for individuals needing high support without residential care.
- Intensive Outpatient Program (IOP) 3–5 weekly sessions focusing on therapy, relapse prevention, and medication management.
- Outpatient Programs (OP) 1–2 sessions weekly for ongoing support or step-down care.
- Telehealth Mental Health & Addiction Care Online therapy and medication management for flexible treatment access.
Effective Therapies for Co-Occurring Disorders
- Cognitive Behavioral Therapy (CBT) Restructures negative thought patterns and builds healthier coping strategies.
- Dialectical Behavior Therapy (DBT) Supports emotional regulation, impulsivity reduction, and stabilization.
- Contingency Management (CM) Offers rewards for sobriety and meeting treatment goals.
- Assertive Community Treatment (ACT) Provides intensive, community-based support for individuals with severe disorders.
- Medication Management Psychiatric medications may be prescribed for depression, anxiety, bipolar disorder, schizophrenia, or other conditions alongside addiction treatment.
