BACKES, Bárbara; ZANON, Regina Basso  and  BOSA, Cleonice Alves. Language regression in autism spectrum disorder: a systematic review. Psicol. teor. prat. [online]. 2017, vol.19, n.2, pp. 215-241. ISSN 1516-3687.

A significant portion of children with Autism Spectrum Disorder (ASD) is affected by the loss of language skills. This study's objective was to systematically review papers addressing this phenomenon characterizing the loss of skills in ASD. We systematically searched bibliographic references in five databases: PubMed, Web of Science, PsycINFO, Lilacs, and Scielo. Two independent judges selected and extracted data. The search resulted in 30 studies. Language regression and the loss of other skills tended to occur around 24 months of age. Beginning in 2000, studies in the field became more frequent, with a refined operational definition of the phenomenon. Significant gaps were identified and can motivate the development of future research, such as a lack of prospective studies and the need to discuss the conceptual definition of developmental regression.
