The Movement Disorder Society (MDS) is an international
professional society of clinicians, scientists, and other healthcare
professionals, who are interested in Parkinson's disease, related
neurodegenerative and neurodevelopmental disorders, hyperkinetic movement disorders, and abnormalities in muscle tone and motor control.
The Movement Disorder Society was founded in 1985 on the initiative of
Professors Stanley Fahn and C. David Marsden, whose leadership and
vision guided the expansion of clinical expertise and research in this
field. The organization merged in 1988 with the International Medical
Society for Motor Disturbances.
