In Dr. Colin Ross's book on Multiple Personality Disorder, he states that psychotropic drugs will not cure MPD. He said tranquilizers work during the intense therapy where he is trying to get the patient to remember all the abuse/trauma that they experienced as a toddler. This is the stuff that was blanked out or denied by the patient's own mind. When the patient is forced to remember that trauma it also brings back all the emotional pain and fear associated with the trauma. Dr. Ross also suggests that the patient be hospitalized during this phase of treatment to prevent self abuse or suicide.
