I linked to Wikipedia, but I originally read the abstract of a different study, which might have examined diphenhydramine specifically rather than many anticholinergic drugs. The abstract of the article cited on Wikipedia makes it clear that it's a cumulative effect, and that they studied outcomes in older adults. So I think Wikipedia describes the research incorrectly. https://pubmed.ncbi.nlm.nih.gov/25879993/ https://pubmed.ncbi.nlm.nih.gov/25879993/
