Can someone please link to the study? I take an anticholinergic and like to stay on top of the latest information. So far the actual study output has been fairly disappointing in quality, and the public rationale for not taking the drug is more subjective-intuitive, getting suppositional and reaching feels-right conclusions when one could reasonably expect hard measurement. I'm not against quitting but I'll be damned if I'm going to take my finger off a button that consistently provides me 8+h sleep and obliterates depression symptoms without being really circumspect about it. Also, no family history of dementia here.
