Is exenatide the game-changer we need in Parkinson's disease? #PreventiveNeurology #PredictPD Would you participate in a study to define your future risk of getting Parkinson's Disease (PD)? In other words would you like to know you are likely to develop PD in the future? A lot of people answer by saying it depends if you have a treatment to prevent PD. At present we don't, but the study below of a exenatide , a glucagon-like peptide-1 (GLP-1) receptor agonist, suggests it may be neuroprotective in patients with established PD. If this study's findings are confirmed in larger phase 3 studies and leads to exenatide being licensed as a disease-modifying therapy, or DMT, for PD changes all this. This means we can take people at high-risk of developing PD and randomise them to receive either placebo or exenatide to see if it can prevent, or at least delay the onset of, PD. This study alone creates the incentive for people from the general public to participate in po
