Kind: research · Impact: medium

## In brief

- A study published in JAMA Network Open found that anticholinergic medications for overactive bladder may not increase dementia risk.
- The comparison was made against beta-3 agonists, a newer drug class presumed to be safer for the brain.
- The finding challenges long-held fears about anticholinergic bladder drugs and dementia.

## Why it matters

Anticholinergic drugs are commonly prescribed for overactive bladder, so evidence that they may not raise dementia risk bears directly on how clinicians weigh treatment options for patients.
