Piotrowski signs
Piotrowski signs are ten signs of organic brain disease that can be found from having patients analyze Rorschach tests.[1] They were identified by Zygmunt Piotrowski, who analyzed the Rorschach test interpretations of patients with organic brain disease, central nervous system diseases (non-cerebral), and conversion disorder. He found that the patients with cortical-subcortical damage (those with organic brain disease) had interpretations that were more abnormal than those with non-cerebral organic abnormalities and conversion disorder.[2]
