Sex differences in typical development can provide context for understanding ASD. Baron-Cohen ("Trends Cogn Sci" 6(6):248-254, 2002) suggested ASD could be considered an extreme expression of normal male, compared to female, phenotypic profiles. In this paper, sex-specific M-CHAT scores from N = 53,728 18-month-old toddlers, including n…

Uzun Cicek, Ayla; Sari, Seda Aybuke; Mercan Isik, Cansu – Journal of Mental Health Research in Intellectual Disabilities, 2020
Introduction: Intellectual disability (ID) is characterized by limitations in cognitive and adaptive functioning. The aim of this study is to examine sociodemographic characteristics, perinatal and childhood risk factors, and prevalence of psychiatric and biomedical comorbidities in children with ID. Methods: 260 patients with ID were included in…

Van Den Heuvel, Ellen; Manders, Eric; Swillen, Ann; Zink, Inge – Journal of Intellectual & Developmental Disability, 2017
Background: Children with 22q11.2 deletion syndrome (22q11.2DS) are reported to have socio-communicative impairments. Although many of these children are diagnosed with intellectual disability (ID) and/or autism spectrum disorder (ASD), these populations are seldom used as control groups. Hence, information regarding syndrome-specific…

Taylor, Lauren J.; Maybery, Murray T.; Wray, John; Ravine, David; Hunt, Anna; Whitehouse, Andrew J. O. – Journal of Autism and Developmental Disorders, 2013
Extensive empirical evidence indicates that the lesser variant of Autism Spectrum Disorders (ASD) involves a communication impairment that is similar to, but milder than, the deficit in clinical ASD. This research explored the relationship between the broader autism phenotype (BAP) among parents, an index of genetic liability for ASD, and proband…

Lee, Nancy Raitano; Wallace, Gregory L.; Adeyemi, Elizabeth I.; Lopez, Katherine C.; Blumenthal, Jonathan D.; Clasen, Liv S.; Giedd, Jay N. – Journal of Child Psychology and Psychiatry, 2012
Background: Supernumerary sex chromosome aneuploidies (X/Y-aneuploidies), the presence of extra X and/or Y chromosomes, are associated with heightened rates of language impairments and social difficulties. However, no single study has examined different language domains and social functioning in the same sample of children with tri-, tetra-, and…

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…

Rossignol, Daniel A.; Frye, Richard E. – Developmental Medicine & Child Neurology, 2011
Aim: The aim of this study was to investigate melatonin-related findings in autism spectrum disorders (ASD), including autistic disorder, Asperger syndrome, Rett syndrome, and pervasive developmental disorders, not otherwise specified. Method: Comprehensive searches were conducted in the PubMed, Google Scholar, CINAHL, EMBASE, Scopus, and ERIC…

Moruzzi, Sara; Ogliari, Anna; Ronald, Angelica; Happe, Francesca; Battaglia, Marco – Journal of Autism and Developmental Disorders, 2011
While social impairment, difficulties with communication, and restricted repetitive behaviors are central features of Autism Spectrum Disorders, physical clumsiness is a commonly co-occurring feature. In a sample of 398 twin pairs (aged 8-17 years) from the Italian Twin Registry we investigated the nature of the co-variation between a psychometric…

Richman, D. M.; Barnard-Brak, L.; Bosch, A.; Thompson, S.; Grubb, L.; Abby, L. – Journal of Intellectual Disability Research, 2013
Background: Presence of an autism spectrum disorder is a risk factor for development of self-injurious behaviour (SIB) exhibited by individuals with developmental disorders. The most salient SIB risk factors historically studied within developmental disorders are level of intellectual disability, communication deficits and presence of specific…

Matson, Johnny L.; Fodstad, Jill C.; Boisjoli, Jessica A. – Research in Autism Spectrum Disorders, 2008
Rett Syndrome is one of the least commonly occurring autism spectrum disorders (ASD), but certainly one of the most devastating. A genetic profile has been identified, but checklists still have an important role for prescreening, especially before expensive genetic testing, and to provide precise strengths and weaknesses with respect to the core…

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…

Philofsky, Amy; Fidler, Deborah J.; Hepburn, Susan – American Journal of Speech-Language Pathology, 2007
Purpose: To describe and compare the pragmatic language profiles of school-age children with autism spectrum disorders (ASD) and Williams syndrome (WS) on a standardized measure to determine whether a standard pragmatics tool can differentiate between 2 groups of children with opposing social presentations and pragmatic language difficulties.…
