<P> The Diagnostic and Statistical Manual of Mental Disorders (DSM) is published by the American Psychiatric Association (APA) and offers a common language and standard criteria for the classification of mental disorders . It is used, or relied upon, by clinicians, researchers, psychiatric drug regulation agencies, health insurance companies, pharmaceutical companies, the legal system, and policy makers together with alternatives such as the ICD - 10 Classification of Mental and Behavioural Disorders, produced by the WHO . </P> <P> The DSM is now in its fifth edition, the DSM - 5, published on May 18, 2013 . The DSM evolved from systems for collecting census and psychiatric hospital statistics, and from a United States Army manual . Revisions since its first publication in 1952 have incrementally added to the total number of mental disorders, although also removing those no longer considered to be mental disorders . </P> <P> The International Classification of Diseases (ICD) is the other commonly used manual for mental disorders and actually the official system for the US . It is distinguished from the DSM in that it covers health as a whole . While the DSM is the most popular diagnostic system for mental disorders in the US, the ICD is used more widely in Europe and other parts of the world . The DSM - IV - TR (4th . ed .) contains specific codes that allows for comparisons between the DSM and the ICD manuals, which may not systematically match because revisions are not simultaneously coordinated . Though recent editions of the DSM and ICD have become similar due to collaborative agreements, each one contains information absent from the other . </P>
