Summary

This trial is testing whether trospium, a drug used to treat urinary incontinence, can also help improve brain function in relation to bladder control.

Who is the study for?
This trial is for women over 60 with urgency urinary incontinence (UUI) or urge-predominant mixed incontinence, occurring at least five times a week for more than three months despite treatment. Participants must not have certain medical conditions like spinal cord injury, severe pelvic issues, or be on conflicting medications.
What is being tested?
The study tests the effectiveness of Trospium against a placebo in managing UUI symptoms and examines how the brain responds to these treatments using MRI scans. It's a randomized double-blind crossover trial, meaning participants will receive both the drug and placebo at different times without knowing which one they're taking.
What are the potential side effects?
While specific side effects are not listed here, Trospium can typically cause dry mouth, constipation, blurred vision and dizziness. Placebos generally do not cause side effects but any unexpected reactions could occur due to the body's response to taking tablets.
