University of Florida neuroscientists at the McKnight Brain Institute are leading a multinational effort to track outcomes for patients with Tourette syndrome who undergo deep brain stimulation surgery, an established treatment for other movement disorders such as Parkinson’s disease that’s now being tested as a potential means to decrease the motor and vocal tics of Tourette syndrome in certain patients.The results indicate an approximate 45 percent reduction in tics one year after the DBS device was implanted.
