What are the similarities and differences between dsm iv and dsm v?

DSM stands for Diagnostic and Statistical Manual of Mental Disorders, released by the American Psychiatric Association. DSM-IV and DSM-V are just the fourth and fifth editions of the manual, respectively. The fourth edition was released in 1994, and the fifth edition is currently in the planning and consultation phase, on its way to being published. So the fifth edition is just an update to the previous edition.
