A study in the journal Lancet Neurology shows that those who have the surgery along with drug treatment had a better quality of life.
The technique called "deep brain stimulation" involves implanting a wire into the brain. It sends electrical impulses to block signals that cause symptoms of Parkinson's, which include, tremors and loss of motor skills.
The study's authors say their results show that surgery is an important treatment option for advanced Parkinson's patients.
