Gene therapy for Parkinson’s advances

Brain surgery to insert genetic cargo improves movement for some

Using brain surgery to insert replacement genes, doctors can alleviate some movement problems in people with Parkinson’s disease. While not all of the gene therapy recipients in a new study improved, the group on average registered tangible gains after getting a gene that revs up production of a much-needed neurotransmitter, researchers report in an upcoming issue of Lancet Neurology.
