Executive functioning in Cornelia de Lange syndrome: domain asynchrony and age-related performance / D. REID in Journal of Neurodevelopmental Disorders, 9-1 (December 2017)
[article]
Titre : Executive functioning in Cornelia de Lange syndrome: domain asynchrony and age-related performance Type de document : Texte imprimé et/ou numérique Auteurs : D. REID, Auteur ; J. MOSS, Auteur ; L. 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.
