Pituitary gland volume in currently depressed and remitted depressed patients
چکیده انگلیسی

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 brain volume (WBV) differences between cMDD patients, rMDD patients and healthy controls. Furthermore, PGV was not correlated with clinical features of depression (e.g., age of onset; number of episodes; and scores on subscales of the Beck Depression Inventory, the Positive Affect and Negative Affect Scale, and the Mood and Anxiety Symptom Questionnaire). In conclusion, PGV does not appear to be a marker of current or past MDD in adult patients.
