Characterizing Daily-Life Social Interactions in Adolescents and Young Adults with Neurodevelopmental Disorders: A Comparison between Individuals with Autism Spectrum Disorders and 22q11.2 Deletion Syndrome
Peer reviewed Peer reviewed
Direct linkDirect link
Feller, Clémence; Ilen, Laura; Eliez, Stephan; Schneider, Maude – Journal of Autism and Developmental Disorders, 2023
Social impairments are common features of 22q11.2 deletion syndrome (22q11DS) and autism spectrum disorders (ASD). The Ecological Momentary Assessment (EMA) allowed access to daily-life information in order to explore the phenomenology of social interactions. 32 individuals with 22q11DS, 26 individuals with ASD and 44 typically developing peers…

Increased Sensory Processing Atypicalities in Parents of Multiplex ASD Families versus Typically Developing and Simplex ASD Families
Peer reviewed Peer reviewed
Direct linkDirect link
Donaldson, Chelsea K.; Stauder, Johannes E. A.; Donkers, Franc C. L. – Journal of Autism and Developmental Disorders, 2017
Recent studies have suggested that sensory processing atypicalities may share genetic influences with autism spectrum disorder (ASD). To further investigate this, the adolescent/adult sensory profile (AASP) questionnaire was distributed to 85 parents of typically developing children (P-TD), 121 parents from simplex ASD families (SPX), and 54…

Brain-Derived Neurotrophic Factor Levels in Autism: A Systematic Review and Meta-Analysis
Peer reviewed Peer reviewed
Direct linkDirect link
Saghazadeh, Amene; Rezaei, Nima – Journal of Autism and Developmental Disorders, 2017
Brain-derived neurotrophic factor (BDNF) plays an important role in activity-dependent synaptic plasticity. Altered blood BDNF levels have been frequently identified in people with autism spectrum disorders (ASD). There are however wide discrepancies in the evidence. Therefore, we performed the present systematic review and meta-analysis aimed at…

Green Snyder, LeeAnne; D'Angelo, Debra; Chen, Qixuan; Bernier, Raphael; Goin-Kochel, Robin P.; Wallace, Arianne Stevens; Gerdts, Jennifer; Kanne, Stephen; Berry, Leandra; Blaskey, Lisa; Kuschner, Emily; Roberts, Timothy; Sherr, Elliot; Martin, Christa L.; Ledbetter, David H.; Spiro, John E.; Chung, Wendy K.; Hanson, Ellen – Journal of Autism and Developmental Disorders, 2016
The 16p11.2 duplication (BP4-BP5) is associated with Autism Spectrum Disorder (ASD), although significant heterogeneity exists. Quantitative ASD, behavioral and neuropsychological measures and DSM-IV diagnoses in child and adult carriers were compared with familial non-carrier controls, and to published results from deletion carriers. The 16p11.2…

van Rijn, Sophie; Stockmann, Lex; Borghgraef, Martine; Bruining, Hilgo; van Ravenswaaij-Arts, Conny; Govaerts, Lutgarde; Hansson, Kerstin; Swaab, Hanna – Journal of Autism and Developmental Disorders, 2014
The present study aimed to gain more insight in the social behavioral phenotype, and related autistic symptomatology, of children with an extra X chromosome in comparison to children with ASD. Participants included 60 children with an extra X chromosome (34 boys with Klinefelter syndrome and 26 girls with Trisomy X), 58 children with ASD and 106…

Emotion Potentiated Startle in Fragile X Syndrome
Peer reviewed Peer reviewed

Ballinger, Elizabeth C.; Cordeiro, Lisa; Chavez, Alyssa D.; Hagerman, Randi J.; Hessl, David – Journal of Autism and Developmental Disorders, 2014
Social avoidance and anxiety are prevalent in fragile X syndrome (FXS) and are potentially mediated by the amygdala, a brain region critical for social behavior. Unfortunately, functional brain resonance imaging investigation of the amygdala in FXS is limited by the difficulties experienced by intellectually impaired and anxious participants. We…

Klusek, Jessica; Hunt, Anna W.; Mirrett, Penny L.; Hatton, Deborah D.; Hooper, Stephen R.; Roberts, Jane E.; Bailey, Donald B. – Journal of Autism and Developmental Disorders, 2015
Although reading skills are critical for the success of individuals with intellectual disabilities, literacy has received little attention in fragile X syndrome (FXS). This study examined the literacy profile of FXS. Boys with FXS (n = 51; mean age 10.2 years) and mental age-matched boys with typical development (n = 35) participated in…

Emberti Gialloreti, Leonardo; Pardini, Matteo; Benassi, Francesca; Marciano, Sara; Amore, Mario; Mutolo, Maria Giulia; Porfirio, Maria Cristina; Curatolo, Paolo – Journal of Autism and Developmental Disorders, 2014
Recent years have seen an increase in the use of retinal nerve fiber layer (RNFL) evaluation as an easy-to-use, reproducible, proxy-measure of brain structural abnormalities. Here, we evaluated RNFL thickness in a group of subjects with high functioning autism (HFA) or with Asperger Syndrome (AS) to its potential as a tool to study autism…
