Reported childhood abuse is associated with low serotonin transporter binding in vivo in major depressive disorder

Abstract

Reported childhood abuse is associated with lower 5-HTT BP(P) in this sample of subjects with major depression, consistent with other reports that childhood adversity can lower serotonergic function permanently. Lower 5-HTT BP(P) may represent a biological pathway through which early life stress predisposes to the development of subsequent psychiatric illness, including major depressive disorder.
