Higher Neural Changes Following Anticholinergic Beta 3 Agonist or Placebo in Patients With Overactive Bladder

Brief description of study

Women presenting with overactive bladder symptoms will be randomized to one of 3 arms (anticholinergic, beta-3 agonist, placebo). They will undergo baseline cognitive testing, functional MRI of the brain. Cognitive testing and functional MRI will be repeated after taking their double blinded intervention for 30 days.

Detailed Study Description

Women presenting to the urology clinic with complaints of urinary urgency, frequency in the absence of urinary tract infection or other obvious pathology will be screened for inclusion/exclusion criteria. Qualifying subjects will be consented.

Baseline health information, bladder symptom questionnaires (Overactive Bladder-questionnaire(OABq), Patient Perception of Bladder Condition (PPBC)), Personal Health Questionnaire-9 (PHQ-9),Hamilton Anxiety Rating Scale (HAM-A), Montreal cognitive assessment (MoCA) will be given. If baseline depression (PHQ-9 score 15 or greater),dementia (MoCA score 25 or less), anxiety (HAM-A score 25-30) are noted the subject is excluded. 15 patients will be recruited from Baylor Scott & White Health Urology clinic, and 15 patients will be recruited from Houston Methodist Urology clinic.

They will schedule a date within 1 month for the Rey Auditory Verbal Learning Test (RAVLT) and brain functional MRI (fMRI). RAVLT test is performed, followed by resting state fMRI and memory task during fMRI. Vials of medication will be distributed. Vials will be labeled 1-30 and will contain 30 tablets each. The anticholinergic and beta-3 agonist tablets will be encapsulated to look identical to the placebo tablet. Subjects will be reimbursed at this visit. fMRI images at baseline and post-intervention will be analyzed by a radiologist for incidental findings.

One week and two weeks after initiating their tablets, phone interviews will inquire about pill count, side effects, and any new medications. Follow up testing date will be scheduled during the call. The same questions will be repeated at completion of the tablets (30 days after initiation).

At completion of the tablets, subjects return to Houston Methodist for repeat RAVLT and fMRI. Subjects will be reimbursed the other half of their compensation at this visit.

An expert physicist will analyze the BOLD signal intensity and FC pattern in a priori selected regions of interest before and after interventions.
