title: Disappearance of tardive dyskinesia during catatonic stupor.
abstract: A 61-year-old man diagnosed as having catatonic schizophrenia was treated with neuroleptics for many years. From 1983 he showed tardive dyskinesia on trunk and limbs as well as orofacial dyskinesia. In September 1985 he displayed a catatonic stupor several times. With the outbreak of the stupor the dyskinesia disappeared and vice varsa. This finding induces the hypothesis that the dopaminergic system is suppressed during catatonic stupor in such a way that tardive dyskinesia is no longer visible.
