Tardive dystonia induced by atypical neuroleptics: a case report with olanzapine.

We report the case of a 17-year-old-boy with schizophrenia who developed tardive dystonia after 9 months of treatment with olanzapine. This case and the relevant literature show that when neuroleptic treatment is indicated, switching to another atypical neuroleptic might be helpful for both tardive dystonia and schizophrenia. In such a case, clozapine appears to be the first-line therapeutic option.
