Treatment for Parkinson's Disease looks promising

July 9, 2008

Many with the disease suffer from rigidity or involuntary tremors making it difficult to walk or even sit still.

But a procedure called 'deep brain stimulation' can interrupt the tremors. Doctors implant electrodes in the brain and a pacemaker-like device in the chest.

The device then fires pulses to make the nerves work more normally. The latest study shows 70-percent of patients who had the procedure, reported significant improvement of their symptoms.

But experts say it's not a cure and the surgery is not easy.
