WHO Press Release 8th March 2024 

The WHO has announced the release of ICD-11 CDDR, a new comprehensive diagnostic manual for mental, behavioural, and neurodevelopmental disorders. 

The CDDR is a clinical version of ICD-11, which was adopted by the World Health Assembly in May 2029 and formally adopted in January 2022. The new release is based specifically on the mental, behavioural, and neurodevelopmental disorders chapter of ICD-11. It is intended to equip mental health professionals and qualified non-specialists like primary care physicians, nurses, occupational therapists, and social workers with a comprehensive understanding of these disorders, regardless of their role in diagnostic assignment.

According to the press release issued by the WHO on Friday, the updates include:

• Guidance on diagnosis for several new categories added in ICD-11, including complex post-traumatic stress disorder, gaming disorder and prolonged grief disorder.
• Behavioural and neurological disorders, including attention to how disorders appear in childhood, adolescence, and older adults.
• The provision of culture-related guidance for each disorder, including how disorder presentations may differ systematically by cultural background.
• The incorporation of dimensional approaches, for example, in personality disorders recognizes that many symptoms and disorders exist on a continuum with typical functioning."
