Dystonia
DBS appears to be most effective in those with primary or hereditary dystonic conditions such as torticollis or cervical dystonia and generalized dystonia. It can also help tardive dyskinesia, a movement disorder caused by certain medications. The level of benefit from DBS is not as significant in secondary dystonia associated with cerebral palsy and/or other types of damage to the brain. More research is needed to determine how to best treat these conditions.
DBS for the treatment of dystonia involves administering a well-controlled electrical current into the globus pallidus, the malfunctioning portion of the brain.
