Abstract

Major depressive disorder (MDD) has been associated with increased pituitary gland volume (PGV), which is thought to reflect stress-related dysregulation related to hypothalamic-pituitary-adrenal (HPA) axis activity. However, it is unclear whether PGV alteration reflects a "dynamic" change related to current mood instability or if it is a stable marker of illness vulnerability. In this study we investigated PGV in currently depressed patients (cMDD) (n = 31), remitted depressed patients (rMDD) (n = 31) and healthy controls (n = 33), using 1.5 Tesla magnetic resonance imaging (MRI). The groups were matched for age and gender. We found no significant PGV, intra-cranial volume (ICV) or whole br..
