The Pisa Syndrome: A Report of Two Cases

Abstract

Ekbom et al (1972) described dystonic syndromes that appeared as a side-effect to treatment with the butyrophenone group of neuroleptic drugs. These symptoms consisted of tonic flexion of the trunk to one side, accompanied by its slight rotation, in the absence of other concomitant dystonic symptoms. They called this the ‘Pisa syndrome’. A literature survey of neuroleptic-included extrapyramidal side-effects gave little reference to this syndrome (Sovner & DiMascio, 1978; Berger & Rexworth, 1980), but two cases that fit the description of this side-effect are presented here.
