Autism spectrum disorder with disorder of intellectual development and with mild or no impairment of functional language with loss of previously acquired skills – http://id.who.int/icd/entity/40740392

All definitional requirements for both autism spectrum disorder and disorder of intellectual development are met and there is only mild or no impairment in the individual's capacity to use functional language (spoken or signed) for instrumental purposes, such as to express personal needs and desires. In addition, the individual’s clinical history includes a loss of previously acquired skills, most commonly the loss of language and social skills during the second year of life. Loss of previously acquired skills is rare after three years of age, and when it occurs is more likely to involve cognitive and adaptive skills (e.g., loss of bowel and bladder control, impaired sleep) and to present together with increasing emotional and behavioural disturbance.
