Morphological Features in Children with Autism Spectrum Disorders: A Matched Case–Control Study / Heval M. OZGEN in Journal of Autism and Developmental Disorders, 41-1 (January 2011)

Titre : Morphological Features in Children with Autism Spectrum Disorders: A Matched Case–Control Study Type de document : Texte imprimé et/ou numérique Auteurs : Heval M. OZGEN, Auteur ; Gerhard S. HELLEMAN, Auteur ; Rebecca K. STELLATO, Auteur ; Bertine LAHUIS, Auteur ; Emma VAN DAALEN, Auteur ; Wouter G. STAAL, Auteur ; Marije ROZENDAL, Auteur ; Raoul C. HENNEKAM, Auteur ; Frits A. BEEMER, Auteur ; Herman VAN ENGELAND, Auteur Année de publication : 2011 Article en page(s) : p.23-31 Langues : Anglais (eng) Mots-clés : Minor anomalies Common variants Dysmorphology Heterogeneity Etiology Biological marker Index. décimale : PER Périodiques Résumé : This study was designed to examine morphological features in a large group of children with autism spectrum disorder versus normal controls. Amongst 421 patients and 1,007 controls, 224 matched pairs were created. Prevalence rates and odds ratios were analyzed by conditional regression analysis, McNemar test or paired t-test matched pairs. Morphological abnormalities were significantly more prevalent in patients with autism than in the normal control group and 48 morphological features distinguished patients from controls. Our findings show that morphological features are associated with autism. Exploring potential underlying genetic mechanisms of this association might lead to a better understanding of autism.

Titre : Reduced heart rate variability in adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : R. THAPA, Auteur ; Gail A. ALVARES, Auteur ; T. A. ZAIDI, Auteur ; E. E. THOMAS, Auteur ; I. B. HICKIE, Auteur ; S. H. PARK, Auteur ; A. J. GUASTELLA, Auteur Année de publication : 2019 Article en page(s) : p.922-930 Langues : Anglais (eng) Mots-clés : autonomic nervous system biological marker heart rate variability mental health parasympathetic nervous system social development sympathetic nervous system Index. décimale : PER Périodiques Résumé : A growing body of research has suggested heart rate variability (HRV) may be reduced in autism spectrum disorder (ASD) in comparison to neurotypical cohorts. While there have been several studies investigating HRV in children diagnosed with ASD, few studies have been conducted in adults. The objective of the current study was to investigate autonomic nervous system activity as assessed by HRV in adults diagnosed with ASD. We hypothesized that adults with ASD would show a reduction in HRV compared to neurotypical participants. Participants diagnosed with ASD (n = 55) were recruited from the Autism Clinic for Translational Research at the Brain and Mind Centre (University of Sydney) between 2013 and 2017. Neurotypical participants were recruited from advertisements and online media. Resting state heart rate was measured for 5 min while participants sat in an upright position. Results showed there was an overall significant difference in resting-state HRV between adults diagnosed with ASD compared to the neurotypical control group. Logarithmically transformed high frequency (HF) and root mean square of successive differences were particularly decreased in the ASD group, suggesting lower parasympathetic activity. The use of psychotropic medications and comorbidities were associated with reductions in low frequency of HRV. Our data suggest an overall dysregulation in resting autonomic activity in adults with ASD. This may represent an important physiological mechanism leading to potential cardiovascular risk in ASD, which warrants further investigation. Autism Res 2019, 12: 922-930. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: ASD is commonly associated with a range of physical and mental health comorbidities. Autonomic disruptions underlying reductions in heart rate variability (HRV) have been linked to a range of mental and physical health conditions. We assessed resting-state HRV in adults diagnosed with ASD in comparison to healthy individuals. Our results showed reduced heart rate variability in people diagnosed with ASD compared to adults without ASD. These findings implicate a role for autonomic activity as a potentially modifiable risk factor for ASD.
