Dementia and addiction frequently co-occur — each substantially increases the risk for the other, and both must be addressed for lasting recovery.
Why Dementia and Addiction Occur Together
The relationship is bidirectional:
- Many people use substances to self-medicate dementia, creating dependency
- Substances temporarily relieve dementia symptoms but ultimately worsen them
- Addiction itself creates the neurological conditions that drive dementia
- Shared risk factors (trauma, genetics, stress) predispose to both
The Challenge of Treating Both Dementia and Addiction
Treating only one condition while ignoring the other leads to poor outcomes. Integrated dual-diagnosis treatment addressing both simultaneously is most effective.
Treatment for Co-occurring Dementia and Addiction
Integrated programs address dementia and substance use together through:
- Trauma-informed therapy (often underlying both)
- Medication-assisted treatment where appropriate
- Peer support that understands both conditions
- Addressing the dementia symptoms that drive substance use
