The American Parkinson Disease Association (APDA) is the largest grassroots network dedicated to fighting Parkinson’s disease (PD) and works tirelessly to help the approximately one million with PD in the United States live life to the fullest in the face of this chronic, neurological disorder. Founded in 1961, APDA has raised and invested more than $226 million to provide outstanding patient services and educational programs, elevate public awareness about the disease, and support research designed to unlock the mysteries of PD and ultimately put an end to this disease.
