Plasma amine oxidase and clinical features of schizophrenia
R Gruen, M Baron, M Levitt and J Kane
Among 76 chronic schizophrenic patients, plasma amine oxidase activity was
unrelated to paranoid/nonparanoid subtype, narrow/broad diagnostic
criteria, prognosis, or age at onset. These clinical indices do not
identify biological subtypes of schizophrenia with deviant plasma amine
oxidase activity.
