The authors found normal monoamine oxidase (MAO) activity in 40 acute
schizophrenic patients, in contrast to previous reports of a genetically
linked platelet MAO deficit in chronic schizophrenia. Variations in MAO
activity were not significantly associated with the 65 clinical variables
analyzed, although there was a tendency for patients in the low-MAO group
to have more severely impaired reality testing, more paranoid and grandiose
delusions, better prognostic scores, and less restlessness.Abstract Teaser
