What causes parkinsons? Is it curable? Can it cause urinary incontinence?

Unknown. The cause of parkinson's disease is unknown. Some of the major symptoms are caused by loss of neurons in an area of the brainstem that produces dopamine. There is no cure yet for parkinson's but there are many treatments available aimed at improving the symptoms. Urinary incontinence is a common symptom in parkinson's disease and results from inability of the brain to suppress bladder emptying.
Overactive bladder. Parkinson's is a degenerative disorder where the brain stops producing dopamine. While there is no cure, treatments for early symptoms are effective. Urinary incontinence is common and unusually these symptoms are over active bladder symptoms; trouble making to the restroom once an urge occurs.
Incontinence. Parkinsons causes a degeneration of the nervous system. Urge incontinence and voiding dysfunctions can be associated with Parkinsons. Follow up with urologist to discuss further.
