An experimental study of executive function and social impairment in Cornelia de Lange syndrome / Lisa NELSON in Journal of Neurodevelopmental Disorders, 9-1 (December 2017)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 9-1 (December 2017) . - p.33 Titre : An experimental study of executive function and social impairment in Cornelia de Lange syndrome Type de document : texte imprimé Auteurs : Lisa NELSON, Auteur ; Hayley CRAWFORD, Auteur ; D. REID, Auteur ; J. MOSS, Auteur ; C. OLIVER, Auteur Article en page(s) : p.33 Langues : Anglais (eng) Mots-clés : Cornelia de Lange syndrome  Down syndrome  Executive function  Social anxiety Index. décimale : PER Périodiques Résumé : BACKGROUND: Extreme shyness and social anxiety is reported to be characteristic of adolescents and adults with Cornelia de Lange syndrome (CdLS); however, the nature of these characteristics is not well documented. In this study, we develop and apply an experimental assessment of social anxiety in a group of adolescents and adults with CdLS to determine the nature of the social difficulties and whether they are related to impairments in executive functioning. METHODS: A familiar and unfamiliar examiner separately engaged in socially demanding tasks comprising three experimental conditions with a group of individuals with CdLS (n = 25; % male = 44; mean age = 22.16; SD = 8.81) and a comparable group of individuals with Down syndrome (DS; n = 20; % male = 35; mean age = 24.35; SD = 5.97). Behaviours indicative of social anxiety were coded. The Behavior Rating Inventory of Executive Function-Preschool version, an informant measure of executive function, was completed by participants' caregivers. RESULTS: Significantly less verbalisation was observed in the CdLS group than the DS group in conditions requiring the initiation of speech. In the CdLS group, impairments in verbalisation were not associated with a greater degree of intellectual disability but were significantly correlated with impairments in both planning and working memory. This association was not evident in the DS group. CONCLUSIONS: Adolescents and adults with CdLS have a specific difficulty with the initiation of speech when social demands are placed upon them. This impairment in verbalisation may be underpinned by specific cognitive deficits, although further research is needed to investigate this fully.

A Behavioural Assessment of Social Anxiety and Social Motivation in Fragile X, Cornelia de Lange and Rubinstein-Taybi Syndromes / Hayley CRAWFORD in Journal of Autism and Developmental Disorders, 50-1 (January 2020)

Here, the effects of adult familiarity and nature of interaction on social anxiety and social motivation were investigated in individuals with fragile X (FXS; n = 20), Cornelia de Lange (CdLS; n = 20) and Rubinstein-Taybi (RTS; n = 20) syndromes, compared to individuals with Down syndrome (DS; n = 20). The Social Anxiety and Motivation Rating Scale was employed whilst participants completed four social tasks, each administered separately by a familiar adult, and also by an unfamiliar adult. Compared to participants with DS, those with FXS and RTS exhibited high levels of social anxiety but similar levels of social motivation. Participants with CdLS showed heightened social anxiety and reduced social motivation only during interactions with an unfamiliar adult when active participation was voluntary.

The Repetitive Behaviour Questionnaire was administered to caregivers of adults with Williams (n = 96), Prader-Willi (n = 103) and Down (n = 78) syndromes. There were few group differences, although participants with Williams syndrome were more likely to show body stereotypies. Individuals with Williams syndrome also showed more hoarding and less tidying behaviours than those with Down syndrome. IQ and adaptive ability were negatively associated with repetitive questioning in people with Williams syndrome. The profile of repetitive behaviour amongst individuals with Williams syndrome was similar to the comparison syndromes. The cognitive mechanisms underlying these behaviours in genetic syndromes warrant further investigation.

Executive functioning in Cornelia de Lange syndrome: domain asynchrony and age-related performance / D. REID in Journal of Neurodevelopmental Disorders, 9-1 (December 2017)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 9-1 (December 2017) . - p.29 Titre : Executive functioning in Cornelia de Lange syndrome: domain asynchrony and age-related performance Type de document : texte imprimé Auteurs : D. REID, Auteur ; J. MOSS, Auteur ; Lisa NELSON, Auteur ; L. GROVES, Auteur ; C. OLIVER, Auteur Article en page(s) : p.29 Langues : Anglais (eng) Mots-clés : Behavioural phenotype  CdLS  Cornelia de Lange  Executive functioning Index. décimale : PER Périodiques Résumé : BACKGROUND: The aim of this study was to examine executive functioning in adolescents and adults with Cornelia de Lange syndrome (CdLS) to identify a syndrome and age-related profile of cognitive impairment. METHODS: Participants were 24 individuals with CdLS aged 13-42 years (M = 22; SD = 8.98), and a comparable contrast group of 21 individuals with Down syndrome (DS) aged 15-33 years (M = 24; SD = 5.82). Measures were selected to test verbal and visual fluency, inhibition, perseverance/flexibility, and working memory and comprised both questionnaire and performance tests. RESULTS: Individuals with CdLS showed significantly greater impairment on tasks requiring flexibility and inhibition (rule switch) and on forwards span capacity. These impairments were also reported in the parent/carer-rated questionnaire measures. Backwards Digit Span was significantly negatively correlated with chronological age in CdLS, indicating increased deficits with age. This was not identified in individuals with DS. CONCLUSIONS: The relative deficits in executive functioning task performance are important in understanding the behavioural phenotype of CdLS. Prospective longitudinal follow-up is required to examine further the changes in executive functioning with age and if these map onto observed changes in behaviour in CdLS. Links with recent research indicating heightened responses to oxidative stress in CdLS may also be important.
