This document discusses the history of psychological treatments from ancient times to the present. Early treatments included exorcism and trephining based on beliefs in spirit possession. In ancient Greece, Hippocrates viewed disorders as having natural causes, treated with baths, exercise, and massage. Later, mentally ill individuals were often chained and punished. Dr. Pinel advocated for more humane treatment. Today, treatments include biomedical therapies like drugs and psychotherapy. Psychotherapy aims to help clients resolve problems and includes psychoanalytic, humanistic, and cognitive approaches. Therapists now consider cultural factors in treatment.
