The term psychiatry was first used by a German doctor, Johann Reil, in 1808 However ,psychiatry as a field did not became popular unti Sigmund Freud came along. Freud proposed a new theory of personality that focused on the role of the unconscious. Before that time,psychologists were concerned primarily with the conscious aspects of the mind. These aspects include perceptions,thoughts,memories,and daydreams of which a person is aware. Freud's new theory came out of his work with various patients who were suffering from hysteria. Freud believed that unconscious drives were important in shaping the personality. The psychiatrist's purpose, as Freud saw it,was to help patients become aware of unconscious patterns. He believed such patterns caused problems with healthy functioning. Freud called his method of treatment "psychoanalysis.
