A surgical procedure is helping patients diagnosed with Parkinson's live with the disease.

The procedure is called deep brain stimulation.

DBS uses a surgically implanted, battery-operated medical device called a neurostimulator. The device is similar to a pacemaker.

The neurostimulator delivers electrical stimulation to certain parts of the brain that cause movement, blocking the nerve signals that cause tremors and other symptoms of Parkinson's disease.

Currently, the procedure is only used for patients whose symptoms can't be controlled with medication.

According to the Parkinson's Disease Foundation, 1 million Americans are living with Parkinson's.
