About our virtual education series 

Our strong commitment towards patient-centered initiatives is reflected in “Understanding the Disease,” an educational series for people diagnosed with Parkinson’s disease (PD) and their families. This patient-centered initiative aims to provide a quarterly clinical and research update on the most critical innovations in the diagnosis and treatment of PD and a moment of discussion between the OSU providers and the PD community. Topics will range from the diagnostic assessment of parkinsonisms and related disorders to the management of motor symptoms, non-motor symptoms, mood & cognition, and the choice of simple and more advanced therapeutic options, as well as new research developments and ongoing clinical trials.  Click here for the latest PD education event video and resources.
