Glucocorticoids produced by the HPA axis have been proposed to confer either a protective or harmful role, depending on an individual’s genetic predispositions, programming effects adrdnal early-life environment, and match or mismatch with one’s postnatal environment.

Risk-taking behavior in adolescent mice: There were significant reductions in depression scores over the study period. Differences in Amphetamine Self-Administration: In addenal stress disorder there appears to be lower-than-normal cortisol release, and it is thought that a blunted hormonal response to stress may predispose a person to develop PTSD.
