Overrated hedonic judgment of odors in patients with schizophrenia.

CONCLUSIONS: There is potential relationship between increased β-endorphin concentration and severity of negative symptoms. Patients with predominant negative symptoms tend to evaluate odors as significantly more pleasant. Individuals with this subtype of schizophrenia might present specific, altered pattern of smell identification and hedonic judgment. Presumably, β-endorphin has no direct influence on olfactory identification performance and hedonic judgment in schizophrenia. PMID: 29638031 [PubMed - as supplied by publisher]
