In the back of this edition of the DSM are the revisions from the last edition. Already, the rules have changed. Here are the new definions of what’s acceptable, what’s normal, what’s sane. Inhibited Male Orgasm is now Male Orgasmic Disorder. What was Psychogenic Amnesia is now Dissociative Amnesia. Dream Anxiety Disorder is now Nightmare Disorder. Edition to edition, the symptoms change. Sane people are insane by a new standard. People who used to be called insane are the picture of mental health.
