Grand Challenges in Parkinson's Disease & Rallying to the Challenge 2018 Grand Challenges in Parkinson’s Disease brings together hundreds of scientists, clinicians and people with Parkinson’s to explore the latest Parkinson’s disease research. The theme for 2018 is Non-Motor Symptoms, which will highlight the roles of the gastrointestinal tract, the olfactory system and the immune system in the onset and progression of Parkinson’s. The Van Andel Research Institute (VARI) and The Cure Parkinson’s Trust are thrilled to once again host Rallying to the Challenge, a parallel meeting for people with Parkinson’s, advocates and caregivers that explores how the Parkinson’s community can impact and accelerate research.
