Anticholinergic Drug Burden and Risk of Incident MCI and Dementia: A Population-based Study

imageObjective:

We investigated whether anticholinergic drug use was related to developing mild cognitive impairment (MCI) or dementia in older adults at the population level.

Methods:

We used an Anticholinergic Rating (ACR) scale, Clinical Dementia Rating, APOE genotype, and number of prescription medications. We examined time to incident MCI and incident dementia in a population-based cohort (n=1959). We assessed whether developing MCI or dementia was associated with (1) any anticholinergic drug use, (2) total ACR score, or (3) number of anticholinergic drugs taken.

Results:

Taking any anticholinergic drug was significantly associated with higher risk of developing MCI; however, higher ACR score or higher number of anticholinergic drugs, compared with lower, were not associated with greater risk of developing MCI. We found no significant relationship between…
