Increased risk of dementia among patients with overactive bladder treated with an anticholinergic medication compared to a beta-3 agonist: a population-based cohort study.

The use of anticholinergic medications among patients with OAB was associated with an increased risk of new-onset dementia compared to beta-3 agonist users. These results address the potential protopathic bias present in other studies on this topic and support the association between anticholinergic medication use and dementia.
