Over four decades ago, the distinguished epidemiological psychiatrist Norman Sartorius wrote, “the history of psychiatric classification is in fact a history of psychiatry.”1 During the 1960s and 1970s, Sartorius had been at the center of research by the World Health Organization (WHO) on the international classification and prevalence of mental disorders. During that era, the organization significantly transformed its classificatory manual, the International Statistical Classification of Diseases and Related Health Problems (ICD), releasing the ICD–9 in 1977. The ICD is the standard international manual for recording mortality and morbidity data for insurance and epidemiological purposes. WHO is currently in the final stages of completing its latest update to the text, ICD–11.
