About the International Association of Parkinsonism and Related Disorders
Over fifty years ago, the Association of Parkinsonism and Related Disorders was established by the World Federation of Neurology to promote and monitor research developments, as well as to foster communication among neuroscientists in this field. Today, this association is an international, professional association of clinicians, scientists and other healthcare professionals who are interested in neurodegenerative disorders like Parkinson's disease, secondary parkinsonisms, hyperkinetic and hypokinetic movement disorders, and more generally any disorder affecting muscle tone and motor control.
