Neo, Wei Siong; Tonnsen, Bridgette L. – Journal of Autism and Developmental Disorders, 2019
Children with neurogenetic syndromes (NGS) experience comorbid challenging behaviors and psychopathology. We examined challenging behaviors in 86 toddlers and preschoolers across three NGS [Angelman syndrome (AS), Prader--Willi syndrome (PWS), and Williams syndrome (WS)] and 43 low-risk controls (LRC), using the Child Behavior Checklist for Ages…

Thomason, Molly Mishler; McCarthy, John; Goin-Kochel, Robin P.; Dowell, Lauren R.; Schaaf, Christian P.; Berry, Leandra N. – Journal of Autism and Developmental Disorders, 2020
Truncating variants of the "MAGEL2" gene, one of the protein-coding genes within the Prader-Willi syndrome (PWS) critical region on chromosome 15q11, cause Schaaf-Yang syndrome (SYS)--a neurodevelopmental disorder that shares several clinical features with PWS. The current study sought to characterize the neurobehavioral phenotype of SYS…

Siu, Michelle T.; Goodman, Sarah J.; Yellan, Isaac; Butcher, Darci T.; Jangjoo, Maryam; Grafodatskaya, Daria; Rajendram, Rageen; Lou, Youliang; Zhang, Rujun; Zhao, Chunhua; Nicolson, Rob; Georgiades, Stelios; Szatmari, Peter; Scherer, Stephen W.; Roberts, Wendy; Anagnostou, Evdokia; Weksberg, Rosanna – Journal of Autism and Developmental Disorders, 2021
Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Baptista, Joana; Sampaio, Adriana; Fachada, Inês; Osório, Ana; Mesquita, Ana R.; Garayzabal, Elena; Duque, Frederico; Oliveira, Guiomar; Soares, Isabel – Journal of Autism and Developmental Disorders, 2019
This study compared maternal responsiveness to children with two neurodevelopmental disorders sharing different but, in some cases, overlapping social phenotypes--Williams syndrome (WS) and autism spectrum disorder (ASD)--and explored the relations between maternal responsiveness and child emotional/behavioural problems (EBP). The sample included…

Bakken, Trine Lise; Hoidal, Siv Helene – International Journal of Developmental Disabilities, 2019
Background: Mental health services for patients intellectual disabilities (ID) and additional mental illnesses are only sparsely studied. Objective: The objective was to describe a representative sample of patients with ID in a specialized psychiatric department. Methods: Data were collected from case files in a 7-year period. Of 143 invited…

Wolfenden, C.; Wittkowski, A.; Hare, D. J. – Journal of Autism and Developmental Disorders, 2017
The prevalence of autism spectrum disorder (ASD) in many genetic disorders is well documented but not as yet in Mucopolysaccharidosis type III (MPS III). MPS III is a recessively inherited metabolic disorder and evidence suggests that symptoms of ASD present in MPS III. This systematic review examined the extant literature on the symptoms of ASD…

Beaudet, Arthur L. – Child Development, 2013
Chromosomal microarray analysis (CMA) has emerged as a powerful new tool to identify genomic abnormalities associated with a wide range of developmental disabilities including congenital malformations, cognitive impairment, and behavioral abnormalities. CMA includes array comparative genomic hybridization (CGH) and single nucleotide polymorphism…

Schaal, David W. – Behavior Analyst, 2012
This article presents an introduction to "The Behavior-Analytic Origins of Constraint-Induced Movement Therapy: An Example of Behavioral Neurorehabilitation," by Edward Taub and his colleagues (Taub, 2012). Based on extensive experimentation with animal models of peripheral nerve injury, Taub and colleagues have created an approach to overcoming…

Gadow, Kenneth D.; Roohi, Jasmin; DeVincent, Carla J.; Kirsch, Sarah; Hatchwell, Eli – Journal of Autism and Developmental Disorders, 2010
Investigated association of single nucleotide polymorphism (SNP) rs301430 in glutamate transporter gene ("SLC1A1") with severity of repetitive behaviors (obsessive-compulsive behaviors, tics) and anxiety in children with autism spectrum disorder (ASD). Mothers and/or teachers completed a validated DSM-IV-referenced rating scale for 67 children…

Kuenssberg, Renate; McKenzie, Karen; Jones, Jill – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Research continues to try and pinpoint the etiological role of particular genes and brain structure in autistic spectrum disorder (ASD), but despite a host of biological, genetic and neuropsychological research, the symptom profile of pervasive developmental disorders (PDDs) are not yet linked to etiological theory. Debate continues around whether…

Gadow, Kenneth D.; Drabick, Deborah A. G. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
Examined autism spectrum disorder (ASD) and schizophrenia spectrum disorder (SSD) symptoms in a clinically referred, non-ASD sample (N = 1160; ages 6-18) with and without oppositional defiant disorder (ODD). Mothers and teachers completed "DSM-IV"-referenced symptom checklists. Youth with ODD were subdivided into angry/irritable symptom (AIS) or…

Van Hulle, Carol A.; Schmidt, Nicole L.; Goldsmith, H. Hill – Journal of Child Psychology and Psychiatry, 2012
Background: Although impaired sensory processing accompanies various clinical conditions, the question of its status as an independent disorder remains open. Our goal was to delineate the comorbidity (or lack thereof) between childhood psychopathology and sensory over-responsivity (SOR) in middle childhood using phenotypic and behavior-genetic…

Muller, Ralph-Axel – Mental Retardation and Developmental Disabilities Research Reviews, 2007
Past autism research has often been dedicated to tracing the causes of the disorder to a localized neurological abnormality, a single functional network, or a single cognitive-behavioral domain. In this review, I argue that autism is a "distributed disorder" on various levels of study (genetic, neuroanatomical, neurofunctional, behavioral).…

It is hypothesised that autism symptoms are present in Attention-Deficit/Hyperactivity Disorder (ADHD), are familial and index subtypes of ADHD. Autism symptoms were compared in 821 ADHD probands, 1050 siblings and 149 controls. Shared familiality of autism symptoms and ADHD was calculated using DeFries-Fulker analysis. Autism symptoms were higher…
