What Is Dual Diagnosis?

A person with a dual diagnosis shows signs of both a mental health disorder and a substance use disorder.

Nearly half of individuals with a substance use disorder—around 8 million adults in the U.S.—also have a mental illness, a condition often called a co-occurring disorder.

A major challenge of co-occurring disorders is how the conditions influence each other. It can be hard to determine which came first, and they often create a cycle that worsens both issues.

For example, a person might drink heavily due to depression, but the alcohol can intensify their depression, prompting even more drinking, and the cycle continues.

What are the Common Mental Disorders Affecting Substance Users?

The four most common mental health disorders among people with substance use issues are depression, anxiety, post-traumatic stress disorder (PTSD), and bipolar disorder.

Common Mental Disorders Explained

Clinical
Depression

Major depressive disorder, or clinical depression, is a severe mood disorder that impacts how you feel, think, and behave. It can cause deep sadness, hopelessness, feelings of worthlessness, and even suicidal thoughts or attempts.

Generalized Anxiety
Disorder

Generalized Anxiety Disorder (GAD) is characterized by excessive worry occurring most days for at least six months. This worry can involve work, health, social situations, and other areas, often interfering with daily life.

Post-Traumatic
Stress Disorder

Post-Traumatic Stress Disorder (PTSD) develops after a person experiences a frightening or traumatic event. Those with PTSD often relive the trauma through flashbacks and nightmares.

Bipolar
Disorder

Bipolar disorder is a condition marked by extreme mood swings due to unusual changes in energy, activity, and focus. All three forms of bipolar disorder involve cycles of elevated and depressive moods.
