The Parkinson's Disease Foundation (PDF) is a leading national presence in Parkinson's disease research, education and public advocacy. We are working for the nearly one million people in the US who live with Parkinson's by funding promising scientific research to find the causes of and a cure for Parkinson's while supporting people with Parkinson's, their families and caregivers through educational programs and support services. Since its founding in 1957, PDF has funded over $80 million worth of scientific research in Parkinson's disease, supporting the work of leading scientists throughout the world. At the heart of PDF's work is the participation of people with Parkinson's. Whether it is through our People with Parkinson's Advisory Council, which advises us on all projects, or the Clinical Research Learning Institute, which trains people with PD to play a part in clinical research - the perspective of people living with Parkinson's ensures that our work is on target and meets the needs of the community. PDF offers a variety of educational publications and programs for people with Parkinson's, their caregivers and families and allied health professionals. These materials can help answer questions about Parkinson's disease symptoms, medications, medical care, exercise and nutrition, among other issues.
