Choline Killers - OTC / Rx

There are many kinds of prescription drugs and over-the-counter (OTC) medications that cause memory loss by blocking the neurotransmitter acetylcholine. Long term use is not required. Memory loss may be noticeable in as little as 60 days .

Low acetylcholine can lead to a group of symptoms that resemble dementia including mental confusion, brain fog, incoherent speech, delirium, blurred vision, memory loss, and hallucinations.

Many popular OTC products for treating allergies, colds, cough, sinus problems, skin irritations, insomnia, headaches and pain contain diphenhydramine.

A large study of seniors found that seniors who took OTC medications (like Benadryl - diphenhydramine) are at significantly increased risk for developing dementia and Alzheimer's.
You can find a complete list of medications that contain diphenhydramine at Drugs.com.

Their brain wave patterns showed these men were unconscious as if they were drunk or in a coma , but were actually asleep.This means these men were not experiencting the restorative sleep their brains needed to consolidate new memories or maintain and repair itself .


Cholesterol medications might be the single worse group of drugs for your brain. One quarter of your brain is composed of cholesterol, which is needed to make neurotransmitters - chemicals that the brain cells use to communicate with each other.

I used a docongestant nasal spray, knowing it's anticholinergic. But I needed a good night's sleep. Even 2 sprays/nostril made me feel terrible the next day. And my self-testing showed my body wanted double the amounts of choline I usually take. Good blog, Sue. thanks
