Substance use and other addictive disorders in international classification of Diseases-11, and their relationship with diagnostic and statistical Manual-5 and international classification of Diseases-10

The beta draft version of the forthcoming eleventh edition of the World Health Organization's medical classificatory system, International Classification of Diseases (ICD-11) is in the public domain, and the final approved version is due for release in 2018. In this beta draft of ICD-11, the section named “disorders due to substance use or addictive behaviours” under chapter 6 (Mental, behavioral, or neurodevelopmental disorders) has recommended some major amendments in terms of both form and content. There are proposed changes in the diagnostic categories, both elimination and addition of new categories. Alterations have also been made in diagnostic criteria and classes of psychoactive drugs. In this perspective paper, we discuss and analyze the proposed changes and their relationship with the American Psychiatric Association's Diagnostic and Statistical Manual 5th edition as well as the current version of ICD. In particular, we also highlight how sociocultural factors may have influenced some of these changes and provide an Asian perspective wherever relevant
