Examples
- Oxybutynin (highest concern)
- Tolterodine
- Solifenacin
What to Do
Discuss possible alternatives, including:
- Mirabegron
- Pelvic floor therapy
- Bladder training exercises
7. First-Generation Antihistamines
Examples
- Diphenhydramine (Benadryl)
- Chlorpheniramine
- Hydroxyzine
- Doxylamine
What Research Suggests
Long-term use has been associated with cognitive decline because these medications can affect brain signaling pathways.
What to Do
Ask about newer antihistamines that may have lower cognitive risk, such as:
- Cetirizine
- Loratadine
- Fexofenadine
8. Statins (Controversial)
Used for: High cholesterol
What Research Shows
Large clinical trials have generally found no significant evidence of cognitive harm from statins. Their cardiovascular benefits remain well established.
What to Do
Do not stop statin medications without medical guidance.
General Recommendations
- Never stop medications abruptly.
- Request a medication review from your doctor or pharmacist.
- Use the lowest effective dose for the shortest appropriate time.
- Ask whether deprescribing is appropriate for long-term medications.
- Consider non-drug approaches when possible.
- Monitor memory or cognitive changes and report concerns early.
Bottom Line
Some medications—particularly strong anticholinergics, benzodiazepines, and certain sleep aids—have been associated with an increased risk of dementia, especially when used long term.
However, these findings show associations, not proof of causation. For many people, the benefits of treatment still outweigh the potential risks.
The most effective approach is to stay informed, review medications regularly, and make treatment decisions together with your healthcare provider.
