Minimize anticholinergic medications
Evidence grade: Essential
Anticholinergic drugs are medicines that block the brain chemical acetylcholine and are widely used for allergies, sleep, bladder control, and mood. The most common brands include Benadryl (allergy), Unisom (sleep), and "PM" pain relievers like Advil PM and Tylenol PM (which use the same sedating ingredient, diphenhydramine). This category also includes widely prescribed bladder relaxants like Ditropan and Detrol, motion sickness pills like Dramamine, and certain antidepressants such as Paxil and Elavil.

How to practice Minimize anticholinergic medications
Use only for short-term relief when necessary. Occasional use (a night or two) is fine; daily or chronic use is the problem. If you have been taking these for more than a few months, talk to your physician about potential substitutes that don't increase dementia risk, where possible.
The evidence behind Minimize anticholinergic medications
Acetylcholine is crucial for learning and memory. Long-term use of some of these drugs, especially in older adults, has been tied to a 40–60 percent higher risk of dementia in very large observational studies. The risk rises with total lifetime dose. Mechanistic work shows reduced brain activity in memory regions even after short exposure.
