For most of us, sadness is a mood that comes and goes, but for others, it becomes a debilitating disease with life threatening implications. In this program we explore the mysteries of Depression. We travel through the realms of diagnosis and treatment; learning how drugs like Prozac and psychotherapy help victims. We also learn about manic depressive behavior and forms of depression unique to men and women. Our host, Kat, discovers electroshock therapy and the promising frontiers of brain imaging and drug research.
