The Signs Of Depression, From Dr. Gail Saltz (WATCH)

Depression is partly biological, but there can be other psychological causes. When psychiatrist Dr. Gail Saltz met with me on Mondays With Marlo, she described the symptoms, which include an interruption of sleep, loss of pleasure in things that you used to enjoy, loss of libido and change in your appetite. Dr. Saltz also reviewed the treatments for depression, including medication for severe cases and talk therapies.
