<P> The DSM - 5 was published on May 18 , 2013 , superseding the DSM - IV - TR , which was published in 2000 . The development of the new edition began with a conference in 1999 , and proceeded with the formation of a Task Force in 2007 , which developed and field - tested a variety of new classifications . In most respects DSM - 5 is not greatly changed from DSM - IV - TR . Notable changes include dropping Asperger syndrome as a distinct classification ; loss of subtype classifications for variant forms of schizophrenia ; dropping the `` bereavement exclusion '' for depressive disorders ; a revised treatment and naming of gender identity disorder to gender dysphoria , and removing the A2 criterion for posttraumatic stress disorder ( PTSD ) because its requirement for specific emotional reactions to trauma did not apply to combat veterans and first responders with PTSD . In addition , the DSM - 5 is the first `` living document '' version of a DSM . </P>
