Effect of Age on Platelet 5-HT Concentrations in Healthy Controls, Depressed and Schizophrenic Patients

Abstract

The influence of age on platelet 5-HT concentrations was investigated in 85 male unipolar depressed inpatients, 113 male schizophrenic inpatients and 81 normal male controls. The correlation coefficients between platelet 5-HT concentrations and age within groups were very low and nonsignificant. Our results suggest that higher platelet 5-HT content, observed in schizophrenic patients, could not be ascribed to the influence of age.
