Urinary Disturbance in Parkinson’s Disease – Overactive Bladder
Urinary disturbance or problems with urination is a common, though late, feature of Parkinson’s disease and may be the cause of much embarrassment to the patient. The main function of the bladder is to store urine and then empty it at a suitable time and place but due to degenerative changes in the basal ganglia in Parkinson’s disease, there is interference with the nerve signals responsible for bladder control, resulting in an overactive or irritable bladder. This causes symptoms of urinary dysfunction such as frequency of micturition, urgency, urinary incontinence, and incomplete emptying of the bladder.
