Memory changes can feel unsettling—especially when they appear unexpectedly. While cognitive decline is not considered an inevitable part of aging, some medications may affect brain health. The goal is not fear, but awareness, so you can discuss potential risks and benefits with your doctor.
Important Context
- Association does not equal causation. Many studies show links between certain medications and cognitive decline, but this does not prove they directly cause dementia.
- Benefits still matter. These drugs often treat serious medical conditions. For many people, the benefits outweigh the potential risks.
1. Benzodiazepines
Examples: Xanax, Valium, Ativan, Klonopin
Used for: Anxiety, insomnia, panic disorders, muscle spasms
What Research Suggests
A 2025 meta-analysis found these medications were associated with:
- A 15% increased risk of dementia
- A 21% increased risk of Alzheimer’s disease
The association appeared stronger with long-term use.
What to Do
Short-term use is generally considered lower risk. If you use these medications long term, ask your doctor about tapering strategies or alternatives such as cognitive behavioral therapy (CBT).
2. Anticholinergic Drugs (High Concern)
