Qualitative study showing 82% of Parkinson's patients with overactive bladder report situational triggers (mean 1.6), notably running water, that provoke urinary urgency.

Limited direct value for molecular therapeutic discovery but informs development of tailored behavioral interventions and symptom-management strategies to improve quality of life in PD.

Lower-urinary-tract symptoms are common in Parkinson's disease (PD) and are a key autonomic symptom affecting quality of life. We demonstrate that situational triggers of urinary urgency are extremely common in a qualitative study of participants with overactive bladder and PD. 82% reported at least one trigger, and the mean number were 1.6. Running water was a consistent theme, however many were highly specific. This work is important for looking at developing tailored behavioural therapies.
