title: Neuroleptic malignant syndrome superimposed on tardive dyskinesia.
abstract: A 30-year-old man with a 3-year history of tardive dyskinesia developed a neuroleptic malignant syndrome while having reserpine and lithium; his symptoms worsened following three doses of neuroleptic medication and improved with bromocriptine. The pre-existing dyskinesia made the presentation confused, and delayed proper diagnosis.
