Langues : Anglais (eng) Mots-clés : Adolescent  Autism Spectrum Disorder/epidemiology  Case-Control Studies  Child  Child, Preschool  Female  Humans  Male  Morning Sickness/epidemiology  Nausea/epidemiology  Pregnancy Index. décimale : PER Périodiques Résumé : Background: Nausea and vomiting during pregnancy (NVP) is thought to be caused by changes in maternal hormones during pregnancy. Differences in hormone exposure during prenatal life have been implicated in the causal pathways for some cases of autism spectrum disorder (ASD). However, no study has investigated whether the presence and severity of NVP may be related to symptom severity in offspring with ASD. Methods: A large sample of children with ASD (227 males and 60 females, aged 2 to 18 years) received a clinical assessment, during which parents completed questionnaires regarding their child's social (Social Responsiveness Scale, SRS) and communication (Children's Communication Checklist-2nd edition, CCC-2) symptoms. Parents also reported on a 5-point scale the frequency and severity of NVPs during the pregnancy of the child being assessed: (1) no NVP during the pregnancy, (2) occasional nausea, but no vomiting, (3) daily nausea, but no vomiting, (4) occasional vomiting, with or without nausea, and (5) daily nausea and vomiting. Results: Impairments in social responsiveness in offspring, as indexed by SRS total score, significantly increased as a function of the frequency and severity of their mothers' NVP, as did the level of language difficulties as indexed by the Global Communication Composite of the CCC-2. Conclusions: The strong, positive association between increasing frequency and severity of NVP and ASD severity in offspring provides further evidence that exposure to an atypical hormonal environment during prenatal life may affect neurodevelopment and contribute to the ASD phenotype. Given that the measure of NVP symptoms in the current study was based on retrospective recall, replication of this finding is required before strong conclusions can be drawn.

The misnomer of 'high functioning autism': Intelligence is an imprecise predictor of functional abilities at diagnosis / Gail A. ALVARES in Autism, 24-1 (January 2020)  

Public ISBD [article]  inAutism > 24-1 (January 2020) . - p.221-232 Titre : The misnomer of 'high functioning autism': Intelligence is an imprecise predictor of functional abilities at diagnosis Type de document : Texte imprimé et/ou numérique Auteurs : Gail A.

VARCIN, Auteur ; J. WRAY, Auteur ; Andrew J. O. WHITEHOUSE, Auteur Article en page(s) : p.221-232 Langues : Anglais (eng) Mots-clés : adaptive behaviour  autism spectrum disorders  cognitive impairment  intellectual disability Index. décimale : PER Périodiques Résumé : 'High functioning autism' is a term often used for individuals with autism spectrum disorder without an intellectual disability. Over time, this term has become synonymous with expectations of greater functional skills and better long-term outcomes, despite contradictory clinical observations. This study investigated the relationship between adaptive behaviour, cognitive estimates (intelligence quotient) and age at diagnosis in autism spectrum disorder. Participants (n = 2225, 1-18 years of age) were notified at diagnosis to a prospective register and grouped by presence (n = 1041) or absence (n = 1184) of intellectual disability. Functional abilities were reported using the Vineland Adaptive Behaviour Scales. Regression models suggested that intelligence quotient was a weak predictor of Vineland Adaptive Behaviour Scales after controlling for sex. Whereas the intellectual disability group's adaptive behaviour estimates were close to reported intelligence quotients, Vineland Adaptive Behaviour Scales scores fell significantly below intelligence quotients for children without intellectual disability. The gap between intelligence quotient and Vineland Adaptive Behaviour Scales scores remained large with increasing age at diagnosis for all children. These data indicate that estimates from intelligence quotient alone are an imprecise proxy for functional abilities when diagnosing autism spectrum disorder, particularly for those without intellectual disability. We argue that 'high functioning autism' is an inaccurate clinical descriptor when based solely on intelligence quotient demarcations and this term should be abandoned in research and clinical practice.
