Gene therapy hope for Parkinson's
An experimental treatment for Parkinson's that delivers billions of copies of a gene to the brain to calm overactive circuitry has had what researchers call 'extremely encouraging' results, with no side effects. The gene therapy aims to replicate the success of deep brain stimulation surgery, AP reports. The small study at Weill Cornell Medical College in New York focused on testing the safety of the procedure rather than its effectiveness, but the initial results are promising - practically eradicating all symptoms in one patient.
