anticholinergics

The correlation is not between Benadryl exactly, but a class of drugs called anticholinergics of which Benadryl is one.

Older antihistamines were anticholinergics, the latter of which are famous for causing vivid auditory, visual and somatic hallucinations.

Most deliriants/anticholinergics are toxic at the doses you need to take for strong psychoactive effects.

Galantamine counteracts the effects of anticholinergics by inhibiting the enzyme that breaks down acetylcholine.

To note, hallucinations (actually, they cause delirium) from anticholinergics are very different from hallucinations from psychedelics, which are closer to visual distortions instead.

This and other studies have not found correlations between antihistamine anticholinergics and dementia.

Long term use of anticholinergics in general has been strongly linked to the development of various severe health issues, including alzheimers and dementia.

What cholinergics and anticholinergics have you tried and what were your experiences?

For example, I would not take a Benadryl unless I was having a serious allergic reaction, because of the known risks of anticholinergics.

The only other options involve anticholinergics, extrapyramidal issues, electricity, magnets, and/or brain surgery.

Like many other anticholinergics (including Datura), if taken without first actually experiencing the poisoning, it results in a deep delirium with complete loss of control over one's actions.

Should have gone to a psychoneuroimmunologist… shame it’s such an overlooked and rare specialty; anti-histamines are often quite powerful anticholinergics, especially when combined, and will substantially perturbe autonomic function.

Yes:( luckily it may be okay, being in the category “Possible anticholinergics include those listed with a score of 1”.

Finally, these studies did not take into account that certain anticholinergics are used to manage insomnia and depression, prodromal conditions that can be seen in early but undiagnosed dementia, leading to protopathic bias." I had other concerns as well, and these items alone are a pretty big deal.

Anticholinergics, the medicines in the article, have been suspected for quite a while, though proof has been lacking.

Anticholinergics are associated with an increase of risk of dementia, and diphenhydramine is a pretty strong one, considering its OTC nature.
