The ICD-11 set independent categories of Stress-related disorders and Dissociative disorders, removing them from the sub-category list of the ICD-10 category of Neurotic, stress-related and somatoform disorders. These new categories, respectively, included attachment disorders and depersonalization-derealizaiton disorder, previously included in different domains. This reflects the paradigm change in ICD, which came to pay increased attention to severe stress and dissociation as principles of division. The ICD-11 Stress-related disorders are similar to the equivalent category of DSM-5 in that both included attachment disorders, and different in that the former has included new diagnosis of complex PTSD and prolonged grief disorder and discarded acute stress reaction from diagnostic nomenclature. The ICD-11 Dissociative disorders are similar to DSM-5 in that they increased the number of conversion subtypes, and different that the former included conversion subtypes while the latter set a different category of Somatoform disorders. The decision of discarding acute stress disorder reflects the basic principle of ICD not to medicalize experiences culturally accepted. The distinction between medicine and culture is fundamental for ICD that is to be used globally and can be an issue of debate. Both Stress-related and Dissociative categories are related to abuse, violence, disaster etc., and the diagnosis is often influenced by culture as to how they are medically harmful. Debate and change in these categories reflect the scope of psychiatrists' activity in the society and their witnessing the victims in reality.
