Abstract

Dystonia is a syndrome of sustained muscle contractions, causing ­abnormal postures, twisting, and repetitive movements. Dystonic appearance may be mimicked by other neurological diseases in which sustained abnormal postures may be present, but which are not considered a true dystonia, and hence are called pseudodystonia. Some forms of pseudodystonia are neurological emergencies, requiring urgent evaluation and treatment. Atlanto-axial subluxation, infectious torticollis, and tetanus all require appropriate measures; otherwise they will result in medical disasters. In this chapter, we discuss causes, evaluation, and management of pseudodystonic emergencies.
