Abstract
- The Pisa syndrome is a rare extrapyramidal side effect caused by neuroleptic treatment. Its characteristics are the twist-ing and bending to one side of the upper thorax, the neck, and the head. To our knowledge, there have been no reports of Pisa syndrome in risperidone therapy. We report four male patients with Pisa syndrome in risperidone therapy. Significant points to be noted here are the absence of any extrapyramidal symptoms prior to risperidone therapy, occur-rence in risperidone therapy with small dosages, and delayed spontaneous recovery on discontinuation of risperidone.
