Loss of language in early development of autism and specific language impairment / Andrew PICKLES in Journal of Child Psychology and Psychiatry, 50-7 (July 2009)
[article]
Titre : Loss of language in early development of autism and specific language impairment Type de document : Texte imprimé et/ou numérique Auteurs : Andrew PICKLES, Auteur ; Tony CHARMAN, Auteur ; Gina CONTI-RAMSDEN, Auteur ; Zoë SIMKIN, Auteur ; Emily SIMONOFF, Auteur ; Gillian BAIRD, Auteur ; Tom LOUCAS, Auteur ; Susie CHANDLER, Auteur ; Milena FALCARO, Auteur Année de publication : 2009 Article en page(s) : p.843-852 Langues : Anglais (eng) Mots-clés : Language-loss autism specific-language-impairment-(SLI) early-language-development SNAP Index. décimale : PER Périodiques Résumé : Background: Several authors have highlighted areas of overlap in symptoms and impairment among children with autism spectrum disorder (ASD) and children with specific language impairment (SLI). By contrast, loss of language and broadly defined regression have been reported as relatively specific to autism. We compare the incidence of language loss and language progression of children with autism and SLI.
Methods: We used two complementary studies: the Special Needs and Autism Project (SNAP) and the Manchester Language Study (MLS) involving children with SLI. This yielded a combined sample of 368 children (305 males and 63 females) assessed in late childhood for autism, history of language loss, epilepsy, language abilities and nonverbal IQ.
Results: language loss occurred in just 1% of children with SLI but in 15% of children classified as having autism or autism spectrum disorder. Loss was more common among children with autism rather than milder ASD and is much less frequently reported when language development is delayed. For children who lost language skills before their first phrases, the phrased speech milestone was postponed but long-term language skills were not significantly lower than children with autism but without loss. For the few who experienced language loss after acquiring phrased speech, subsequent cognitive performance is more uncertain.
Conclusions: Language loss is highly specific to ASD. The underlying developmental abnormality may be more prevalent than raw data might suggest, its possible presence being hidden for children whose language development is delayed.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2008.02032.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=771
