Objective: This study aimed to investigate the relationship between Cognitive Disengagement Syndrome (CDS) symptoms in children/adolescents and their parents within the Turkish population, examining the association with co-occurring ADHD symptoms, peer/social relationships, and total difficulties. Method: The study included 229 parents aged 18 to…

Studying anxiety in neurogenetic syndromes may inform the intersection of biological and developmental risks, facilitating effective and targeted interventions. We longitudinally examined stranger fear in infants and toddlers with fragile X syndrome (FXS; n = 46) and typical controls (n = 33), as well as associations between observed stranger fear…

Background: Williams syndrome (WS) phenotype is described as unique and intriguing. The aim of this study was to investigate the associations between speech-language abilities, general cognitive functioning and behavioural problems in individuals with WS, considering age effects and speech-language characteristics of WS sub-groups. Methods: The…

Children with 22q11.2 deletion syndrome exhibit high rates of social-behavioral problems, particularly in the internalizing domain, indicating an area in need of intervention. The current investigation was designed to obtain information regarding parent and teacher ratings of the social-emotional behavior of children with 22q11DS. Using the Child…

Background: Children with 22q11.2 deletion syndrome (22q11DS) are at risk for social-behavioural and neurocognitive sequelae throughout development. The current study examined the impact of family environmental characteristics on social-behavioural and cognitive outcomes in this paediatric population. Method: Guardians of children with 22q11DS…

Background: Studies have linked the behaviour problems of children with fragile X syndrome (FXS) to maternal well-being, but less is known about how behaviour problems relate to important family factors such as marital satisfaction and family cohesion. Methods: Married mothers of 115 adolescents and adults with FXS completed questionnaires and…

Autism and the related pervasive developmental disorders are a heavily researched group of neurodevelopmental conditions.

This paper provides a review of factors and behaviors that correlate highly with disorders on the autism…

Background: Attention-deficit/hyperactivity disorder (ADHD) symptoms and mathematics ability are associated, but little is known about the genetic and environmental influences underlying this association. Methods: Data came from more than 6,000 twelve-year-old twin pairs from the UK population-representative Twins Early Development Study. Parents…

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…

A review of the literature revealed that mothers with children with fragile X syndrome (FXS) face many challenges, including managing their child's behavior which is a defining characteristic of children with FXS (Epstein, Riley, & Sobesky, 2002). Parents and professionals have become increasingly aware through research and everyday experiences…

Prader-Willi syndrome (PWS) is a rare genetic disorder that adversely impacts child development and health conditions, and is often associated with significant behavioral challenges. In particular, children with PWS typically exhibit extremely high levels of maladaptive behavior (e.g., excessive food seeking, hording, and binging; temper tantrums;…

Background: Although distinctive neuropsychological impairments have been delineated in children with chromosome 22q11 deletion syndrome (22q11DS), social skills and social cognition remain less well-characterised. Objective: To examine social skills and social cognition and their relationship with neuropsychological function/behaviour and…

The aims of this study were to investigate whether subtle PDD symptoms in the context of ADHD are transmitted in families independent of ADHD, and whether PDD symptom familiality is influenced by gender and age. The sample consisted of 256 sibling pairs with at least one child with ADHD and 147 healthy controls, aged 5-19 years. Children who…

Background: This study explores everyday social competence in the lives of persons with three genetic intellectual disability syndromes.
