A diabetes drug could be a breakthrough treatment for stopping Parkinson’s disease in its tracks, a study suggests.People with Parkinson’s who took Exenatide – an existing diabetes medication – for around a year had better motor skills than those who took a placebo.

The results suggest the drug could halt decline in Parkinson’s patients rather than just relieving symptoms.Experts welcomed the University College London (UCL) research as a ‘particularly promising’ step in the search for a treatment to slow or stop the disease.
