The strong evidence for detrimental effects of AC agents on cognition, led the American Urological Association to update its guidelines in 2015 to include mirabegron as an alternative first-line agent for treatment of overactive bladder (OAB). NGB symptoms are very similar to OAB so the conditions are often treated similarly; however, data is lacking on the use of this promising agent for NGB. We thus propose to test the hypothesis that cognition will improve with substitution of mirabegron for the AC agent in elderly persons with SCI who require NGB treatment.~Subjects eligible for enrollment will have been treated with an anticholinergic agent for at least 3 months prior to enrollment. Baseline measurements will be recorded for subjects currently treated with an AC agent, after enrollment, the subject will start treatment with the study drug. Measurements from baseline (AC agent) will be compared to measurements taken after study intervention (mirabegron).
