What is 'dual diagnosis'?

Direct Answer

Dual diagnosis refers to the co-occurrence of a mental health condition and a substance use condition in the same individual. These conditions exist concurrently, meaning they are both present at the same time. This term does not imply that one condition caused the other, nor does it identify the primary condition.

Common Misunderstandings

["Clients with a dual diagnosis are not necessarily experiencing a mental health crisis. They have two distinct, co-occurring conditions.","A dual diagnosis does not mean the individual is more difficult to support. It indicates the presence of multiple conditions that may interact.","The term 'dual diagnosis' does not establish a causal link. It describes co-occurrence, not origin."]

In Practice

The presence of a dual diagnosis means an individual is experiencing both a mental health concern and a substance use concern. For example, a person might have an anxiety disorder alongside a cannabis use disorder. Another example could be depression co-occurring with an alcohol use disorder.

These conditions can influence each other. Symptoms of one condition might worsen the other, or complicate how symptoms are expressed. For instance, anxiety might increase substance use, or substance use might exacerbate depressive symptoms. Understanding dual diagnosis acknowledges this interaction.

What This Does NOT Mean

["This does not mean one condition necessarily caused the other. The relationship can be complex, or they may have developed independently.","This does not include situations where substance use is the sole cause of mental health symptoms that resolve with abstinence. It refers to distinct, enduring conditions.","This does not define a specific type of mental illness or substance use disorder. It is a descriptive term for the presence of two separate categories of conditions."]
