Is it true that anticholinergenics may be linked to cognitive impairment and dementia? what should i use now to put me to sleep?

Here's the news: It is very clear that in older folks, drugs such as Benadryl, (diphenhydramine) with strong anti-cholinergic characteristics, can promote profound confusion, and may even lead to worsening of acetyl-choline deterioration in Alzheimer's. Unlikely to affect you at 28 however. Melatonin seems far safer and likely effective in most cases.
