Parkinson's disease
Clinical research

As of 2022, no disease-modifying drugs (drugs that target the causes or damage) are approved for Parkinson's, so this is a major focus of Parkinson's research. Active research directions include the search for new animal models of the disease and studies of the potential usefulness of gene therapy, stem cell transplants, and neuroprotective agents. To aid in earlier diagnosis, research criteria for identifying prodromal biomarkers of the disease have been established.
