🫀 5. Proton Pump Inhibitors (PPIs)
Examples: Prilosec, Nexium, Prevacid
Used for: Acid reflux, GERD
What research suggests:
Some studies show a possible link between certain PPIs and dementia risk, though results are mixed.
What to do:
Consider lower doses, shorter use, or alternatives like H2 blockers (e.g., famotidine).
💧 6. Overactive Bladder Medications
Examples:
- Oxybutynin (highest risk)
- Tolterodine
- Solifenacin
What to do:
Ask about alternatives like mirabegron or non-drug options (pelvic floor therapy).
🤧 7. First-Generation Antihistamines
Examples:
- Diphenhydramine (Benadryl)
- Chlorpheniramine
- Hydroxyzine
- Doxylamine
What research suggests:
Long-term use is linked to cognitive decline due to brain effects.
What to do:
Switch to newer antihistamines like cetirizine, loratadine, or fexofenadine.
🧠 8. Statins (Controversial)
Used for: High cholesterol
What research shows:
Large clinical trials have found no significant cognitive harm. Benefits for heart health are well established.
What to do:
Do not stop statins without medical advice.
✅ General Recommendations
✅ General Recommendations
- Never stop medications abruptly.
- Request a medication review with your doctor or pharmacist.

- Try non-drug approaches first when possible.
- Monitor cognitive changes and report concerns early.
🔑 Bottom Line
Some medications—especially strong anticholinergics, benzodiazepines, and certain sleep aids—are associated with increased dementia risk, particularly with long-term use.
However, these are associations, not proof of causation. For many people, the benefits of treatment outweigh the risks.
The best approach is simple: stay informed, review your medications regularly, and make decisions in partnership with your doctor.
