Foss-Feig; Jonathan A. Bernstein; Elizabeth Berry-Kravis; Craig M. Powell; Mustafa Sahin; Latha Valluripalli Soorya; Audrey Thurm; Joseph D. Buxbaum; Alexander Kolevzon – American Journal on Intellectual and Developmental Disabilities, 2025
The clinical spectrum of Phelan-McDermid syndrome (PMS) is varied, with wide-ranging degrees of intellectual disability, developmental delays, behavioral abnormalities, and medical features. Different types of genetic variation lead to PMS, and differing genotypes (e.g., size of deletion or type of variant) account for some of this variability,…

Gow, Joan-Beth; Carpino, Lisa A. – Journal of College Science Teaching, 2018
Anorexia nervosa is a complex behavioral disorder with the highest risk of death of any psychological disorder. Between 15% and 20% of those suffering from anorexia die from complications that are attributed either directly or indirectly to self-starvation. Heritability for anorexia is around 0.5, meaning about 50% of the risk for anorexia is…

Silberg, Judy L.; Maes, Hermine; Eaves, Lindon J. – Journal of Child Psychology and Psychiatry, 2012
Background: A critical issue in devising effective interventions for the treatment of children's behavioral and emotional problems identifying genuine family environmental factors that place children at risk. In most twin and family studies, environmental factors are confounded with both direct genetic risk from parents and the indirect effect of…

Mathews, Carol A.; Grados, Marco A. – Journal of the American Academy of Child & Adolescent Psychiatry, 2011
Objective: Tourette syndrome (TS) is a neuropsychiatric disorder with a genetic component that is highly comorbid with obsessive-compulsive disorder (OCD) and attention deficit/hyperactivity disorder (ADHD). However, the genetic relations between these disorders have not been clearly elucidated. This study examined the familial relations among TS,…

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…

Tunnicliffe, Penny; Oliver, Chris – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The research literature notes both biological and operant theories of behavior disorder in individuals with intellectual disabilities. These two theories of genetic predisposition and operant reinforcement remain quite distinct; neither theory on its own is sufficient to explain challenging behavior in genetic syndromes and an integrated approach…

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…

Mick, Eric; McGough, James; Loo, Sandra; Doyle, Alysa E.; Wozniak, Janet; Wilens, Timothy E.; Smalley, Susan; McCracken, James; Biederman, Joseph; Faraone, Stephen V. – Journal of the American Academy of Child & Adolescent Psychiatry, 2011
Objective: A potentially useful tool for understanding the distribution and determinants of emotional dysregulation in children is a Child Behavior Checklist profile, comprising the Attention Problems, Anxious/Depressed, and Aggressive Behavior clinical subscales (CBCL-DP). The CBCL-DP indexes a heritable trait that increases susceptibility for…

Schroeder, Stephen R.; Courtemanche, Andrea – Journal of Mental Health Research in Intellectual Disabilities, 2012
There is a very substantial literature over the past 50 years on the advantages of early detection and intervention on the cognitive, communicative, and social-emotional development of infants and toddlers at risk for developmental delay due to premature birth or social disadvantage. Most of these studies excluded children with severe delays or…

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).…

Biswas, Parthasarathy; Malhotra, Savita; Malhotra, Anil; Gupta, Nitin – Journal of Indian Association for Child and Adolescent Mental Health, 2006
Background: Childhood onset schizophrenia (COS) is a rare disorder. Comparative data on the effect of differential age of onset on clinical profile in schizophrenia are very few. Method: Subjects with COS (n = 15), adolescence onset schizophrenia (AdOS, n = 20) and adulthood onset schizophrenia (AOS, n = 20) were compared on socio-demographic,…
