The cognitive neuropsychological phenotype of carriers of the FMR1 premutation / J. GRIGSBY in Journal of Neurodevelopmental Disorders, 6-1 (December 2014)
[article]
Titre : The cognitive neuropsychological phenotype of carriers of the FMR1 premutation Type de document : Texte imprimé et/ou numérique Auteurs : J. GRIGSBY, Auteur ; Kim CORNISH, Auteur ; D. HOCKING, Auteur ; C. KRAAN, Auteur ; J. M. OLICHNEY, Auteur ; S. M. RIVERA, Auteur ; A. SCHNEIDER, Auteur ; S. SHERMAN, Auteur ; J. Y. WANG, Auteur ; J. C. YANG, Auteur Article en page(s) : p.28 Langues : Anglais (eng) Mots-clés : Cognition disorders Executive function Fmr1 Fxtas Fragile X Fragile X premutation Fragile X-associated tremor/ataxia syndrome Index. décimale : PER Périodiques Résumé : The fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative disorder affecting a subset of carriers of the FMR1 (fragile X mental retardation 1) premutation. Penetrance and expression appear to be significantly higher in males than females. Although the most obvious aspect of the phenotype is the movement disorder that gives FXTAS its name, the disorder is also accompanied by progressive cognitive impairment. In this review, we address the cognitive neuropsychological and neurophysiological phenotype for males and females with FXTAS, and for male and female unaffected carriers. Despite differences in penetrance and expression, the cognitive features of the disorder appear similar for both genders, with impairment of executive functioning, working memory, and information processing the most prominent. Deficits in these functional systems may be largely responsible for impairment on other measures, including tests of general intelligence and declarative learning. FXTAS is to a large extent a white matter disease, and the cognitive phenotypes observed are consistent with what some have described as white matter dementia, in contrast to the impaired cortical functioning more characteristic of Alzheimer's disease and related disorders. Although some degree of impaired executive functioning appears to be ubiquitous among persons with FXTAS, the data suggest that only a subset of unaffected carriers of the premutation - both female and male - demonstrate such deficits, which typically are mild. The best-studied phenotype is that of males with FXTAS. The manifestations of cognitive impairment among asymptomatic male carriers, and among women with and without FXTAS, are less well understood, but have come under increased scrutiny.

The consistently reported PSI weakness in children with autism spectrum disorder (ASD) therefore warrants special assistance and attempts at compensation for the disadvantages associated with these children's low PSI. We investigated the association of PSI scores with age, general cognitive ability [as measured by full-scale IQ (FSIQ)], symptom severity and discrepancy between the WISC-IV indices verbal comprehension (VCI) and perceptual reasoning (PRI) in 101 school children with ASD. The PSI weakness in children with ASD was not related to age, FSIQ, VCI-PRI discrepancy or any of the symptom measures. These findings suggest that school children with ASD independent of their age, level of cognitive ability, VCI-PRI profile and most notably independent of their symptom severity should be entitled to special assistance and compensation in educational settings.
