- Abstract
Objective: To explore imidafenacin's effects on bladder and cognitive function in neurologic overactive bladder (OAB) patients. Methods: Sixty-two subjects (25 men, 37 women; mean age 70 years (25-86) with OAB due to neurologic diseases) were enrolled in the study. We conducted a urinary symptom survey and cognitive tests (MMSE, FAB, ADAS-cog) in all patients. We performed urodynamics in 35 patients and measured real-time near-infrared spectroscopy (NIRS)-urodynamics in eight patients before and after the administration of imidafenacin, an anticholinergic agent, for 3 months at 0.2 mg/day. Results: Imidafenacin significantly ameliorated urinary urgency, nighttime urinary frequency, and quality of life index ( p < 0.05). Three cognitive measures did not change significantly. Urodynamics showed increased bladder capacity ( p < 0.05) but detrusor overactivity did not change significantly. NIRS showed that the subtraction of oxyhemoglobin between the start of filling and the first sensation increased in the bilateral prefrontal area but without statistical significance. Conclusions: Imidafenacin ameliorated bladder sensation without cognitive worsening, with a trend of prefrontal activation. Regarding cognitive function, imidafenacin is safely used in OAB patients due to neurologic diseases. Synopsis: In order to explore imidafenacin (anticholinergic agent)'s effects on bladder and brain function, we performed urinary questionnaire, cognitive tests, urodynamics and near-infrared spectroscopy (selected cases) in 62 overactive bladder (OAB) patients due to various neurologic diseases. As a result, imidafenacin ameliorated bladder sensation without cognitive worsening, with a trend of prefrontal activation. Imidafenacin seems safe in treating OAB patients due to neurologic diseases.
