Cumulative use of strong anticholinergics and incident dementia: a prospective cohort study.

ABSTRACT:

Importance

Many medications have anticholinergic effects. In general, anticholinergic-induced cognitive impairment is considered reversible on discontinuation of anticholinergic therapy. However, a few studies suggest that anticholinergics may be associated with an increased risk for dementia.
