Tachycardia, sweating, and a goiter suggest hyperthyroidism. TD may coexist with other neuroleptic-induced movement disorders, including parkinsonism (manifested by tremor, rigidity, and bradykinesia). Distinguish TD from acute dystonic reactions induced by medications and from neuroleptic withdrawal dyskinesias. Unlike TDs, withdrawal dyskinesias remit within a month after discontinuance of neuroleptics.
