ABSTRACT
A review of the most current literature demonstrates once again that there are fashions in science as well as in symptoms. The great success of current biological treatments for mood disorders has resulted by promoting biological theories while ignoring psychological theories about the nature and etiology of mood disorders. As the quest for understanding of our psychological origins continues, reductionistic , deterministic answers become popular. Yet the pendulum swings and most likely we can expect psychoanalytic (even brain hemispheric?) concepts to reemerge in the next decade since there is, as yet, no unequivocal biochemical basis for mood disorders.
