2. Dual Diagnosis and Psychiatric Comorbidity

Dual diagnosis refers to the coexistence of a mental disorder and a substance use disorder.

This is extremely common among people experiencing homelessness.

Examples include:

Schizophrenia + alcohol dependence

Major depression + opioid use disorder

Bipolar disorder + stimulant misuse

PTSD + benzodiazepine misuse

Psychiatric comorbidity is also frequent:

Depression + anxiety

Personality disorder + addiction

Psychosis + trauma

These combinations increase:

Risk of hospitalisation

Risk of relapse

Suicide risk

Treatment dropout

Housing instability

Fragmented services often treat these conditions separately. Integrated care must treat them together.
