Risk of dementia associated with the use of anticholinergic medications: a review of recent literature.

PURPOSE OF REVIEW: While there is an established association between the use of anticholinergic medications and its effects on cognition, the extent of this impact remains unclear. We outline recent studies addressing this topic.

RECENT FINDINGS: We describe a series of recent articles discussing the risk of dementia associated with anticholinergic medication use in general, with further focus on the risk of overactive bladder (OAB) anticholinergic use, detailing short & long-term use effects, risk variation based on age and gender, and reporting alternative treatment options.

SUMMARY: Anticholinergic medication use bears an increased risk of dementia development, and accelerated cognitive decline in individuals with preexisting dementia, with the risk being related to the medications dosages, length of exposure, and pharmacological profile. β3-adrenoceptor agonists have proven to be a potent alternative for OAB anticholinergics, owing to its safe profile in regards of no clear effects on cognitive function, and having similar efficacy in OAB treatment.
