Avoid These Common Drugs If You Want to Keep Your Brain Sharp and Prevent Dementia – Page 2

These three classes of widely used medications have the most well-documented links to cognitive impairment and increased dementia risk, particularly with long-term use.

1. Anticholinergics: The Primary Culprit

This class of drugs poses the most well-documented risk. They work by blocking acetylcholine, a neurotransmitter absolutely critical for memory, learning, and muscle function. In the brain, this effect essentially starves the memory centers of their essential chemical fuel.

Long-Term Impact: While short-term use can cause temporary confusion, numerous longitudinal studies have linked chronic use to a significantly increased incidence of diagnosed dementia.
Common Examples:
- First-generation antihistamines: Diphenhydramine (Benadryl), hydroxyzine.
- Tricyclic antidepressants (TCAs): Amitriptyline, nortriptyline.
- Overactive bladder medications: Oxybutynin (Ditropan).
- Antispasmodics: For stomach cramps and IBS.
