Corticotropin-releasing factor test in melancholic patients in depressed state versus recovery: A comparative study

The crossover clinical status at the moment of the CRF test doesn't differentiate changes in the HPA axis in melancholic patients, while we did find significant differences in the group of healthy controls in comparison with the groups of melancholic patients both in depressive state and recovery. This supports the hypothesis that hypothalamic pituitary adrenal (HPA) axis shows alterations that remain in depressive patients even after recovery.
