FURTHER EVIDENCE FOR OLFACTORY IDENTIFICATION DEFICITS IN SCHIZOPHRENIA

Forty-seven schizophrenic patients and 36 normal controls, matched for smoking history, were administered the University of Pennsylvania Sme ll Identification Test (UPSIT) and the Picture Identification Test (PI T). Amongst subjects successfully completing the PIT, non-smoking schi zophrenic patients had significantly lower UPSIT scores than non-smoki ng controls. Smoking history and diagnosis did not interact to produce any pronounced effect. No significant gender difference was found. Th ese results suggest schizophrenics display decreased olfactory identif ication even if likely confounders are adequately controlled.
