Summary of major changes to DSM-5

© SPMM Course Summary of major changes to DSM-5 DSM-5 is comprised of three sections: Section 1: An introduction and guidance to use; Section 2: An outline of the diagnostic categories with the newly revised chapters; Section 3: Includes a list of conditions that require further research before their consideration as formal disorders. It also includes details on cultural formulations. A multiaxial system that separately identified personality disorders (Axis II) and medical conditions (Axis III) has been modified. The new multiaxial system now includes only three axes - psychiatric disorder, psychosocial and environmental factors associated with them, and the severity of associated disability. In effect, this means personality disorders are treated with the same importance as other psychiatric disorders. This has moved DSM’s  multiaxial  system  closer  to  ICD’s  multiaxial  system. A brief note on other major changes is given below. Further details are provided downstream when discussing the major disorders.
