The purpose of this study is to study the effect of duloxetine treatment on (1) cognitive functions, the brain mechanisms involved with thinking, reasoning, learning, and remembering; (2) psychosocial functions, how someone interacts with his/her social environment; and (3) the relationship between these two functions, in people who have major depressive disorder, a severe form of depression.
