• Behavioural therapy improves bladder control in Parkinson’s disease
• Self-control by using a voiding diary reduces urinary symptoms
• Effects persist in the long term

Patients suffering from urinary incontinence due to Parkinson’s disease can reduce their urinary symptoms such as miction frequency, miction urgency and increased nocturnal frequency (nyctury) with behavioural therapy. This intervention is also beneficial for patients with impaired cognitive function. This was shown by a Georgic research team that divided 50 patients with Parkinson’s disease into two groups: one group received behavioural therapy and completed a personal voiding diary on a weekly basis; the other group only monitored their urinary symptoms at the start of the study and after eight weeks in the diary.
