RT Journal Article SR Electronic T1 Idiopathic dystonia and cervical spondylotic myelopathy. JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 1424 OP 1426 DO 10.1136/jnnp.52.12.1424 VO 52 IS 12 A1 Waterston, J A A1 Swash, M A1 Watkins, E S YR 1989 UL http://jnnp.bmj.com/content/52/12/1424.abstract AB Cervical myelopathy developed in two patients with idiopathic torsion dystonia. There were marked spondylotic changes in both patients, probably attributable to the incessant dystonic movements of the neck. Previous cervical spine surgery may have exacerbated the myelopathy in one of the patients. Cervical myelopathy complicating idiopathic dystonia must be distinguished from other causes of neurological deterioration, since it may be improved by appropriate neurosurgical treatment.
