Major depressive disorder is a serious mental disorder that profoundly affects an individual's quality of life. Although the aetiologies underlying this disorder remain unclear, an increasing attention has been focused on the influence imposed by psychological stress over depression.

Therefore, we will review classical models along with new methods that will enrich our knowledge of this disorder.
