The movement disorder society and movement disorders: a modern history.

The Movement Disorder Society (MDS) developed out of a merger with two short-lived organizations, the Movement Disorder Society, primarily organized to develop a journal for the subspecialty, and the International Society of Motor Disturbances, primarily organized to develop international congresses. The formal merger of the Movement Disorder Society and the International Society of Motor Disturbances into the Movement Disorder Society took place at the 2nd International Congress of Movement Disorders in Munich, Germany, in June 1992. Whereas the journal, Movement Disorders, and the annual International Congress of Parkinson's Disease and Movement Disorders remain the anchors of the society, the goals now include the development of regional symposia, regional sections, Web-based educational programs, and outreach efforts to include young investigators, wide international membership, and inclusion of non-neurologists, including basic scientists, neurosurgeons, and nonphysician health professionals. Movement Disorders has a continuingly growing subscribership and rising impact factor.
