The present study investigated the performance of children with neurofibromatosis type 1 on computerized assessments of attention and executive function. Relations to ADHD symptomatology were also examined. Participants included 37 children (20 male) with NF1 (9-13 years; M = 11.

Children with neurofibromatosis type 1 (NF1) often have attention difficulties with emerging evidence that these difficulties can be seen even in early childhood. This study aimed to explore the relative utility of two versions of a commonly used computerized attention measure for young children with NF1 and to explore relations with parent-reported attention in young children with NF1. Two independent samples of young children with NF1 participated.

Objective: Research indicates that children with neurofibromatosis type 1 (NF1) have weaknesses in fine and gross motor development in early childhood; however, little is known about the stability and developmental trajectory of motor functioning. We investigated (1) whether motor difficulties are evident and stable in the preschool period in children with NF1 and (2) whether there are particular patterns of motor development in this population.

Methods: Participants with NF1 and a control group of unaffected siblings were enrolled at ages 3-8 years and were assessed yearly.

Objective: Social skills difficulties are commonly reported by parents and teachers of school age (SA) children with neurofibromatosis type 1 (NF1). Investigations of social skills of young children with NF1 are scarce. This study aimed to characterize the emergence of social skills challenges beginning in early childhood, examine social skills longitudinally into SA, and explore interrelations with attention-deficit hyperactivity disorder (ADHD) symptomatology and cognitive functioning among children with NF1 cross-sectionally and longitudinally.

Article Synopsis
  • The study investigates the adaptive behavior of children with neurofibromatosis type 1 (NF1) over time, highlighting that these children show poorer adaptive functioning compared to peers.
  • Researchers assessed 59 children in early childhood and 39 in school age, using various evaluation tools to measure adaptive and executive functioning.
  • Results indicate a significant correlation in adaptive behavior between early childhood and school age, with increased difficulties observed over time, suggesting that executive functioning impacts adaptive behavior in these children.

Aim: We examined key features of two outcome measures for social dysfunction and autism spectrum disorder traits, the Social Responsiveness Scale, Second Edition (SRS-2) and the Social Skills Improvement System - Rating Scales (SSIS-RS), in children with neurofibromatosis type 1 (NF1). The aim of the study was to provide objective evidence as to which behavioural endpoint should be used in clinical trials.

Method: Cross-sectional behavioural and demographic data were pooled from four paediatric NF1 tertiary referral centres in Australia and the United States (N=122; 65 males, 57 females; mean age [SD] 9y 2mo [3y], range 3-15y).

Social difficulties inherent to autism spectrum disorder are often linked with co-occurring symptoms of anxiety and attention deficit hyperactivity disorder (ADHD). The present study sought to examine the relation between such co-occurring symptoms and social challenges. Parents of adolescents with autism (N = 113) reported upon social challenges via the social responsiveness scale (SRS) and anxiety and ADHD symptomatology via the Child Behavior Checklist.

Young adults with ASD experience difficulties with social skills, empathy, loneliness, and social anxiety. One intervention, PEERS® for Young Adults, shows promise in addressing these challenges. The present study replicated and extended the original study by recruiting a larger sample (N = 56), employing a gold standard ASD assessment tool, and examining changes in social anxiety utilizing a randomized controlled trial design.

Objective: Children with neurofibromatosis type 1 (NF1) are at risk for executive functioning (EF) challenges, with little research with preschoolers.

Methods: EF was examined using parent and teacher ratings of preschool-aged children with NF1 ( n  = 26) and parent ratings of unaffected children ( n  = 37) on the Behavior Rating Inventory for Executive Functioning-Preschool Form. Relations to performance on laboratory measures were also examined.

In this study, the language abilities of 30 children with Neurofibromatosis Type 1 (NF1) aged 4-6 years were examined using a standardized measure of language. Relations of language to multiple parental report measures of functional communication, social skills, and attention problems were investigated. Difficulties in core language skills were observed, and more than 1/3 of the children struggled on at least one language index.

Neurofibromatosis-1 is the most common single gene disorder affecting 1 in 3000. In children, it is associated not only with physical features but also with attention and learning problems. Research has identified a downward shift in intellectual functioning as well, but to date, there are no published studies about the everyday adaptive behavior of children with NF1.
