Dystonia

Dystonia is a neurological disorder which affects approximately 30 to 50 in every 100,000 people worldwide.¹

There are two major categories of dystonia.
•      Primary dystonia
•      Secondary dystonia

A person diagnosed with primary dystonia does not have any neurologic signs or brain abnormalities. In addition, the origin of the illness is unknown. Secondary dystonia is associated with a lesion to the central nervous system often caused by an outside factor such as trauma, cerebral palsy or stroke. 

Dystonia can be even further characterized into subcategories.:

•      Generalized dystonia affects the entire body
•      Focal dystonia affects one area of the body
•      Segmental dystonia affects two or more contiguous body         areas
•      Hemidystonia affects one side of the body
