Brain Pacemaker used to treat Parkinson’s

A new study finds that deep brain stimulation works to reduce symptoms in Parkinson’s patients. The subthalamic nucleus (STN) and the globus pallidus interna (GPi), both affecting motor function, are the two areas tested that shows the best signs for improvement from the disease. The procedure begins by placing a fine wire into one of the two areas of the brain and a portable battery delivers a fine tuned electrical current to stimulate the brain. This usually results in dramatic improvements of motor function.

The most common side effect found was over half of the patients developed an infection at the incision site. However, during the two year study, ninety-nine percent of these issues were resolved by the end of the trial.

Parkinson’s Disease affects millions of people world-wide and often begins with motor function problems, rigidity in the muscles, slow movement and reduced ability to balance. As the disease progresses, many patients develop cognitive and mood issues. Depression, apathy, confusion, impaired memory and difficulty sleeping. Over time, medications given to the patient to control early symptoms become less effective.

Perhaps the most famous celebrity with Parkinson’s, Michael J. Fox, was diagnosed with the disease in 1991 and disclosed his condition to the public in 1998. He retired from acting in 2000 but is the founder of the Michael J. Fox Foundation that has raised millions of dollars over the years for research. There is no word yet whether or not Fox will attempt deep brain stimulation for his symptoms of Parkinson’s Disease.
