title: Blood platelet monoamine oxidase activity in schizophrenic children and their families. A preliminary study.
abstract: In this study monoamine oxidase (MAO) activity was measured in blood platelets of 21 individuals (age 2 6/12-19 years) who were diagnosed at preschool age as schizophrenics; MAO activity was not significantly different from that found in normals. An insignificant correlation was found between MAO activity in patients and age; a similar correlation for normals was also insignificant. In a sample of 15 families, no significant correlation between MAO activity of patients and their parents was obtained.
