KJELLGREN, Auteur Article en page(s) : p.163-173 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : 1941 ofthe 3-6-year-old children living in a community outside Gbteborg on the Swedish west coast were screened with a view to identifying all individuals with severe degrees of autistic behaviour. All children in the population were known to well baby clinic staff, and any child suspected of suffering from autism was referred to a specialized clinical research team. The nurses and doctors working in the well baby clinics were well informed about autism. Clinical and ADI-R diagnoses of autism were established after thorough clinical assessments of each suspected case. All children were seen at least twice, and all were over the age of 3 years at the time of diagnosis. The general population prevalence for autism was 3 I in I o,ooo children (9; percent confidence interval 7/ g;). Classic Kanner autism was found in I o in Io,ooo children (9; percent confidence interval-4/24). These rates appear to reflect higher rates than previously reported. Some reasons for the possibly higher prevalence are discussed.

Autism With and Without Regression: A Two-Year Prospective Longitudinal Study in Two Population-Derived Swedish Cohorts / L. THOMPSON in Journal of Autism and Developmental Disorders, 49-6 (June 2019)

Those with regression (n = 62), 20.5% of the combined cohort, were contrasted with those without regression (n = 241) at first assessment (age range 19-60 months) and at 2-year follow-up on a range of measures. The regression group was significantly more functionally impaired, with regard to intellectual function (p < .001), language development (p < .001), and to severity of autism (p < .01) at both T1 and T2. Only 14 (23.3%) had a clearly identified underlying etiology [24 (18.6%) in the non-regressive group]. There were no significant differences between those who had regressed 'from normal' and those who had regressed 'from low' functioning.

Current profiles and early predictors of reading skills in school-age children with autism spectrum disorders: A longitudinal, retrospective population study / J. ASBERG JOHNELS in Autism, 23-6 (August 2019)

Before the age of 3 years, the study cohort underwent a neurodevelopmental assessment following identification in a population-based autism screening. At age 8 years, reading, language and cognition were assessed. Approximately half of the sample (n = 25) were 'poor readers' at age 8 years, meaning that they scored below the normal range on tests of single word reading and reading comprehension. And 18 were 'skilled readers' performing above cut-offs. The final subgroup (n = 10) presented with a 'hyperlexic/poor comprehenders' profile of normal word reading, but poor reading comprehension. The 'poor readers' scored low on all assessments, as well as showing more severe autistic behaviours than 'skilled readers'. Group differences between 'skilled readers' and 'hyperlexics/poor comprehenders' were more subtle: these subgroups did not differ on autistic severity, phonological processing or non-verbal intelligence quotient, but the 'hyperlexics/poor comprehenders' scored significantly lower on tests of oral language. When data from age 3 were considered, no differences were seen between the subgroups in social skills, autistic severity or intelligence quotient. Importantly, however, it was possible to identify oral language weaknesses in those that 5 years later presented as 'poor readers' or 'hyperlexics'.

Etiological influences on the stability of autistic traits from childhood to early adulthood: evidence from a twin study / M. J. TAYLOR in Molecular Autism, 8 (2017)  

Public ISBD [article]  inMolecular Autism > 8 (2017) . - 5p. Titre : Etiological influences on the stability of autistic traits from childhood to early adulthood: evidence from a twin study Type de document : Texte imprimé et/ou numérique Auteurs : M. J. TAYLOR, Auteur ; C. GILLBERG, Auteur ; P. LICHTENSTEIN, Auteur ; S. LUNDSTRÖM, Auteur Article en page(s) : 5p. Langues : Anglais (eng) Mots-clés : Adolescent  Autistic Disorder/*genetics/*psychology  Child  Diseases in Twins  Female  Humans  Longitudinal Studies  Male  Phenotype  Surveys and Questionnaires  Twins/*genetics  *Adulthood  *Autism  *Genetics  *Stability  *Twin study Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorders (ASD) are persistent and lifelong conditions. Despite this, almost all twin studies focus on childhood. This twin study investigated the stability of autistic traits from childhood to early adulthood and explored the degree to which any stability could be explained by genetic or environmental factors. METHODS: Parents of over 2500 twin pairs completed questionnaires assessing autistic traits when twins were aged either 9 or 12 years and again when twins were aged 18. Bivariate twin analysis assessed the degree of phenotypic and etiological stability in autistic traits across this period. Genetic overlap in autistic traits across development was also tested in individuals displaying a broad ASD phenotype, defined as scoring within the highest 5% of the sample. RESULTS: Autistic traits displayed moderate phenotypic stability (r = .39). The heritability of autistic traits was 76-77% in childhood and 60-62% in adulthood. A moderate degree of genetic influences on childhood autistic traits were carried across into adulthood (genetic correlation = .49). The majority (85%) of the stability in autistic traits was attributable to genetic factors. Genetic influences on autistic traits were moderately stable from childhood to early adulthood at the extremes (genetic correlation = .64). CONCLUSIONS: Broad autistic traits display moderate phenotypic and etiological stability from childhood to early adulthood. Genetic factors accounted for almost all phenotypic stability, although there was some phenotypic and etiological instability in autistic traits. Thus, autistic traits in adulthood are influenced by a combination of enduring and unique genetic factors.
