Parkinson's Disease - Prognosis
There is no cure for Parkinson's disease. Drugs may help relieve symptoms for a few or many years. Those symptoms eventually get worse, however. Drug therapy becomes less successful. During the late stages of the disease, psychiatric symptoms become most troubling. These symptoms include problems with sleeping, increasing dementia, hallucinations, and loss of contact with reality.
