Dystonia

 

Dystonia is one of a group of Movement Disorders which also includes Tourette Syndrome.

 

Dystonia is a twisting or abnormal posture that may occur in any body part.  Dystonia may occur at rest, but is always worsened with voluntary movement.  Dystonia is not suppressible and is not associated with an urge.  Unlike tics, dystonia usually interferes with activities such as walking or writing.  This is a rare problem in children and may be due to a number of causes most of which are genetic.  In adults, dystonia occurs more commonly and the cause is generally unknown (idiopathic).  An example of dystonia is writer’s cramp.

 

Dystonia is not known to be linked to Tourette Syndrome.
