Autistic symptomatology and language ability in autism spectrum disorder and specific language impairment / Tom LOUCAS in Journal of Child Psychology and Psychiatry, 49-11 (November 2008)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 49-11 (November 2008) . - p.1184-1192 Titre : Autistic symptomatology and language ability in autism spectrum disorder and specific language impairment Type de document : Texte imprimé et/ou numérique Auteurs : Tom LOUCAS, Auteur ; Tony CHARMAN, Auteur ; Emily SIMONOFF, Auteur ; Andrew PICKLES, Auteur ; Gillian BAIRD, Auteur ; Susie CHANDLER, Auteur ; David MELDRUM, Auteur Année de publication : 2008 Article en page(s) : p.1184-1192 Langues : Anglais (eng) Mots-clés : Autistic-disorder specific-language-impairment SNAP-cohort Index. décimale : PER Périodiques Résumé : Background: Autism spectrum disorders (ASD) and specific language impairment (SLI) are common developmental disorders characterised by deficits in language and communication. The nature of the relationship between them continues to be a matter of debate. This study investigates whether the co-occurrence of ASD and language impairment is associated with differences in severity or pattern of autistic symptomatology or language profile. Methods: Participants (N = 97) were drawn from a total population cohort of 56,946 screened as part of study to ascertain the prevalence of ASD, aged 9 to 14 years. All children received an ICD-10 clinical diagnosis of ASD or No ASD. Children with nonverbal IQ ≥80 were divided into those with a language impairment (language score of 77 or less) and those without, creating three groups: children with ASD and a language impairment (ALI; N = 41), those with ASD and but no language impairment (ANL; N = 31) and those with language impairment but no ASD (SLI; N = 25). Results: Children with ALI did not show more current autistic symptoms than those with ANL. Children with SLI were well below the threshold for ASD. Their social adaptation was higher than the ASD groups, but still nearly 2 SD below average. In ALI the combination of ASD and language impairment was associated with weaker functional communication and more severe receptive language difficulties than those found in SLI. Receptive and expressive language were equally impaired in ALI, whereas in SLI receptive language was stronger than expressive. Conclusions: Co-occurrence of ASD and language impairment is not associated with increased current autistic symptomatology but appears to be associated with greater impairment in receptive language and functional communication.

Parent-Reported Gastro-intestinal Symptoms in Children with Autism Spectrum Disorders / Susie CHANDLER in Journal of Autism and Developmental Disorders, 43-12 (December 2013)

Participants included 132 children with ASD and 81 with special educational needs (SEN) but no ASD, aged 10–14 years plus 82 typically developing (TD) children. Data were collected on GI symptoms, diet, cognitive abilities, and developmental histories. Nearly half (weighted rate 46.5 %) of children with ASD had at least one individual lifetime GI symptom compared with 21.8 % of TD children and 29.2 % of those with SEN. Children with ASD had more past and current GI symptoms than TD or SEN groups although fewer current symptoms were reported in all groups compared with the past. The ASD group had significantly increased past vomiting and diarrhoea compared with the TD group and more abdominal pain than the SEN group. The ASD group had more current constipation (when defined as bowel movement less than three times per week) and soiling than either the TD or SEN groups. No association was found between GI symptoms and intellectual ability, ASD severity, ASD regression or limited or faddy diet. Parents report more GI symptoms in children with ASD than children with either SEN or TD children but the frequency of reported symptoms is greater in the past than currently in all groups.

Regression, Developmental Trajectory and Associated Problems in Disorders in the Autism Spectrum: The SNAP Study / Gillian BAIRD in Journal of Autism and Developmental Disorders, 38-10 (November 2008)

Language regression was reported in 30% with narrowly defined autism, 8% with broader ASD and less than 3% with developmental problems without ASD. A smaller group of children were identified who underwent a less clear setback. Regression was associated with higher rates of autistic symptoms and a deviation in developmental trajectory. Regression was not associated with epilepsy or gastrointestinal problems.
