Can surgery cure Parkinson's forever?

No. Unfortunately parkinson's disease (pd) is not curable. Most surgeries for pd can help with the stiffness, walking problems, and tremor associated with pd. Unfortunately, most patients progress with time into a state of dementia (cognitive difficulties) and this is not preventable by any current medications or surgeries. Fortunately, most pd does not progress very quickly.
Not Exactly. Brain surgery may be considered when drugs fails to control symptoms of parkinson's disease or cause severe or disabling side effects. Surgery is not a cure for parkinson's disease. Drugs are usually still needed after surgery. But surgery can reduce the number and amount of drugs needed to control symptoms. This reduces the side effects caused by drugs while at the same time controlling symptoms.
