The Takeaway
- Some allergy, sleep, anxiety, and bladder medications block a key brain chemical.
- Long-term use of these drugs may increase dementia risk by up to 50%.
- Seniors are especially vulnerable due to already declining brain chemicals.
- Safer alternatives are available — talk with your doctor before making changes.
- Medication check-ups with your pharmacist can uncover hidden risks.

According to multiple large-scale studies, some everyday medications — both prescription and over-the-counter — could be quietly increasing your risk of memory loss and dementia, especially if you’re over 60.
