Case study: worsening Tourette's disorder or withdrawal dystonia?
This case report focuses on withdrawal dystonia, a movement disorder associated with neuroleptics. Its occurrence in a patient with Tourette's disorder complicated the clinical picture. A misinterpretation of the symptoms led to ineffective management of the movement disorder. The presence of increased blinking with facial pain, dystonic movements, and other facial movements at each neuroleptic dose reduction pointed toward withdrawal dystonia rather than toward a worsening of Tourette's disorder. Implications for diagnosis and treatment are discussed.
