Parkinson's advances
The central cause of Parkinson's disease is a lack of a chemical in the brain called dopamine. Now researchers at Rush Presbyterian Hospital in Chicago think they've found a way to make those Cells produce dopamine, by using gene therapy. Researchers injected a new gene to produce dopamine directly into the brains of rhesus monkeys. As a result the dopamine made the symptoms of Parkinson's disappear in all of the monkeys, without returning. Doctors say the treatment may be available for humans in a year.
