Platelet MAO activity and age at onset of depression in elderly depressed women
GS Alexopoulos, KW Lieberman, RC Young and CA Shamoian
Platelet monoamine oxidase (MAO) activity was assayed in 38 elderly
depressed women and 16 matched controls. The depressed women whose illness
began at age 55 or earlier (N = 19) had significantly lower MAO activity
than patients with later onset (N = 19) or controls.
