Adults with Asperger syndrome with and without a cognitive profile associated with “non-verbal learning disability.” A brief report / Agneta NYDEN in Research in Autism Spectrum Disorders, 4-4 (October-December 2010)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 4-4 (October-December 2010) . - p.612-618 Titre : Adults with Asperger syndrome with and without a cognitive profile associated with “non-verbal learning disability.” A brief report Type de document : Texte imprimé et/ou numérique Auteurs : Agneta NYDEN, Auteur ; Maria RASTAM, Auteur ; Annika DAHLGREN SANDBERG, Auteur ; Henrik ANCKARSATER, Auteur ; Lena NIKLASSON, Auteur ; Ola STAHLBERG, Auteur ; Elisabeth WENTZ, Auteur Année de publication : 2010 Article en page(s) : p.612-618 Langues : Anglais (eng) Mots-clés : Adults Asperger-syndrome Neuropsychology Non-verbal-learning-disability Index. décimale : PER Périodiques Résumé : Asperger syndrome (AS) and non-verbal learning disability (NLD) are both characterized by impairments in motor coordination, visuo-perceptual abilities, pragmatics and comprehension of language and social understanding. NLD is also defined as a learning disorder affecting functions in the right cerebral hemisphere. The present study investigates if individuals with AS and a cognitive profile consistent with NLD (i.e. verbal IQ > performance IQ) would also have other problems inherent in NLD, visual memory and attention, reading/writing ability and arithmetic in the presence of preserved verbal memory and attention. Forty-four individuals with AS were assessed with a battery of neuropsychological tests. Reading/writing and arithmetic abilities were investigated. Education and global social adaptive levels were studied. Very few AS participants, even though with NLD cognitive profile showed problems with any of the neurocognitive abilities or academic achievements. However, all had poor global social adaptive functioning and few had paid employment, regardless of their cognitive profile. The present study suggests that AS and NLD are two different conditions even though some individuals in both groups have the verbal IQ > performance IQ profile that has been proposed to be typical of both AS and NLD.

A cognitive endophenotype of autism in families with multiple incidence / Agneta NYDEN in Research in Autism Spectrum Disorders, 5-1 (January-March 2011)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 5-1 (January-March 2011) . - p.191-200 Titre : A cognitive endophenotype of autism in families with multiple incidence Type de document : Texte imprimé et/ou numérique Auteurs : Agneta NYDEN, Auteur ; Maria RASTAM, Auteur ; Véronique GOUSSE, Auteur ; Bibbi HAGBERG, Auteur Année de publication : 2011 Article en page(s) : p.191-200 Langues : Anglais (eng) Mots-clés : Multiple-incidence-families Autism-spectrum-disorders Cognitive-endophenotype Sibpair Autism Index. décimale : PER Périodiques Résumé : Twin and family studies have established that there is a strong genetic basis for autism spectrum disorders. To facilitate the identification of susceptibility genes and to study pathways from gene-brain to cognition a more refined endophenotype-based approach may be useful. The purpose of the present study was to examine the neurocognitive endophenotype of autism, in families with multiple incidence autism. Eighty-six members of 18 families containing at least two individuals with autism were neuropsychological assessed. Children with autism, showed weak central coherence, but this “trait” could not be found in their parents nor in non-affected siblings. All family members, including the sibpairs with autism, showed deficits within executive functions, involving planning ability, but normal set-shifting. The sibpairs with autism – but not their other family members – showed significant correlations within two visuo-spatial tasks. Deficits in executive functions (specifically planning ability) appear to characterize the broader endophenotype of autism. Our findings do not confirm the hypotheses of weak central coherence or deficits in theory of mind as part of the broader endophenotype of autism. Deficits in visual scanning may be a feature of the manifest phenotype of autism.

Executive Function/Attention Deficits in Boys with Asperger Syndrome, Attention Disorder and Reading/Writing Disorder / Agneta NYDEN in Autism, 3-3 (September 1999)  

Public ISBD [article]  inAutism > 3-3 (September 1999) . - p.213-228 Titre : Executive Function/Attention Deficits in Boys with Asperger Syndrome, Attention Disorder and Reading/Writing Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Agneta NYDEN, Auteur ; Christopher GILLBERG, Auteur ; Erland HJELMQUIST, Auteur ; Mikael HEIMAN, Auteur Article en page(s) : p.213-228 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Executive function/attention deficits were examined in children with Asperger syndrome, attention disorder and reading/ writing disorder and in a group of normal children. Neuropsychological tests as well as cognitive tasks measuring different components in the processing of information were used. The measures were divided into Mirsky’s four components of attention, namely ‘sustain’,‘focus-execute’,‘shift’ and ‘encode’. All abnormal groups differed markedly from the normal group on measures of executive function/attention. The group diagnosed as having attention disorder showed the most consistent difficulties. However, no specific marker of ‘executive function deficits’ that could represent the three different disorders was found.
