How a Junkie's Brain Helps Parkinson's Patients
ATASCADERO, California -- In Monterey County Jail, in the spring of 1981, a 21-year-old drug dealer and junkie named Toby Govea lay in bed shaking violently and uncontrollably. Thanks to a bad batch of homemade heroin, Govea had developed symptoms of Parkinson's Disease, an incurable neurological illness that causes muscle rigidity, tremors and eventually loss of movement.
Today, Govea remains incarcerated -- but free of tremors, thanks to a treatment made possible by research on the prisoner's own brain.
The treatment, called deep brain stimulation, has become the leading surgical treatment for Parkinson's, which afflicts 1.5 million Americans. It has been performed on more than 20,000 patients in the past decade.
In July of this year at the Atascadero State Hospital in California, Govea was lucid, and his muscles were still, as he recalled the events that made him a human guinea pig who helped develop a treatment for his own illness.
