S38. SCHIZOPHRENIA PATIENTS WITH PROMINENT NEGATIVE SYMPTOMS HAVE MORE SEVERE OLFACTORY IDENTIFICATION IMPAIRMENTS THAN SCHIZOPHRENIA PATIENTS WITHOUT PROMINENT NEGATIVE SYMPTOMS

摘要

Recent meta-analytic evidence suggested that schizophrenia is associated with olfactory identification impairments. However, it is unclear whether olfactory impairments are related to negative syndrome. Few studies have compared olfactory identification ability in schizophrenia patients with high levels of negative symptoms than those without. Moreover, very few studies have investigated olfactory hedonic appraisal in schizophrenia patients. This study aimed to investigate olfactory identification and hedonic appraisal, and their relationships with negative symptoms.
