Age-related differences in cognition across the adult lifespan in autism spectrum disorder / Anne G. LEVER in Autism Research, 9-6 (June 2016)  

Public ISBD [article]  inAutism Research > 9-6 (June 2016) . - p.666-676 Titre : Age-related differences in cognition across the adult lifespan in autism spectrum disorder Type de document : texte imprimé Auteurs : Anne G. LEVER, Auteur ; Hilde M. GEURTS, Auteur Article en page(s) : p.666-676 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  aging  older adults  cognition  neuropsychology  memory  theory of mind  generativity Index. décimale : PER Périodiques Résumé : It is largely unknown how age impacts cognition in autism spectrum disorder (ASD). We investigated whether age-related cognitive differences are similar, reduced or increased across the adult lifespan, examined cognitive strengths and weaknesses, and explored whether objective test performance is related to subjective cognitive challenges. Neuropsychological tests assessing visual and verbal memory, generativity, and theory of mind (ToM), and a self-report measure assessing cognitive failures were administered to 236 matched participants with and without ASD, aged 20–79 years (IQ > 80). Group comparisons revealed that individuals with ASD had higher scores on visual memory, lower scores on generativity and ToM, and similar performance on verbal memory. However, ToM impairments were no longer present in older (50+ years) adults with ASD. Across adulthood, individuals with ASD demonstrated similar age-related effects on verbal memory, generativity, and ToM, while age-related differences were reduced on visual memory. Although adults with ASD reported many cognitive failures, those were not associated with neuropsychological test performance. Hence, while some cognitive abilities (visual and verbal memory) and difficulties (generativity and semantic memory) persist across adulthood in ASD, others become less apparent in old age (ToM). Age-related differences characteristic of typical aging are reduced or parallel, but not increased in individuals with ASD, suggesting that ASD may partially protect against an age-related decrease in cognitive functioning. Despite these findings, adults with ASD experience many cognitive daily challenges, which highlights the need for adequate social support and the importance of further research into this topic, including longitudinal studies.

Asperger Syndrome and Schizophrenia: A Comparative Neuropsychological Study / Maria MARINOPOULOU in Journal of Autism and Developmental Disorders, 46-7 (July 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-7 (July 2016) . - p.2292-2304 Titre : Asperger Syndrome and Schizophrenia: A Comparative Neuropsychological Study Type de document : texte imprimé Auteurs : Maria MARINOPOULOU, Auteur ; Tove LUGNEGÅRD, Auteur ; Maria Unenge HALLERBÄCK, Auteur ; Christopher GILLBERG, Auteur ; Eva BILLSTEDT, Auteur Article en page(s) : p.2292-2304 Langues : Anglais (eng) Mots-clés : Asperger syndrome  Schizophrenia  Neuropsychology  Intellectual functioning  Executive functions Index. décimale : PER Périodiques Résumé : There has been an increasing interest in possible connections between autism spectrum disorder (ASD) and schizophrenia in the last decade. Neuropsychological comparison studies have, however, been few. The present study examined similarities and differences in intellectual and executive functioning between adults with Asperger syndrome (AS) and adults with schizophrenic psychosis (SP). A group with AS and a group with SP were assessed neuropsychologically with WAIS-III and D-KEFS. Similarities were found between groups, as displayed by an uneven cognitive profile, limitations in working memory, processing speed and some aspects of executive functioning. Full Scale IQ was higher in the AS group. These results add to the current research illuminating similarities and differences between ASD and schizophrenia on a cognitive level.

Associations between birth weight and attention-deficit/hyperactivity disorder symptom severity: indirect effects via primary neuropsychological functions / Burt HATCH in Journal of Child Psychology and Psychiatry, 55-4 (April 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-4 (April 2014) . - p.384-392 Titre : Associations between birth weight and attention-deficit/hyperactivity disorder symptom severity: indirect effects via primary neuropsychological functions Type de document : texte imprimé Auteurs : Burt HATCH, Auteur ; Dione M.

HALPERIN, Auteur Article en page(s) : p.384-392 Mots-clés : ADHD  neuropsychology  birth weight Index. décimale : PER Périodiques Résumé : Background Attention-deficit/hyperactivity disorder (ADHD) has a range of aetiological origins which are associated with a number of disruptions in neuropsychological functioning. This study aimed to examine how low birth weight, a proxy measure for a range of environmental complications during gestation, predicted ADHD symptom severity in preschool-aged children indirectly via neuropsychological functioning. Methods A total of 197 preschool-aged children were recruited as part of a larger longitudinal study. Two neuropsychological factors were derived from NEPSY domain scores. One, referred to as ‘Primary Neuropsychological Function,’ was loaded highly with Sensorimotor and Visuospatial scores. The other, termed ‘Higher-Order Function’ was loaded highly with Language and Memory domain scores. Executive functioning split evenly across the two. Analyses examined whether these neuropsychological factors allowed for an indirect association between birth weight and ADHD symptom severity. Results As both factors were associated with symptom severity, only the Primary Neuropsychological Factor was associated with birth weight. Furthermore, birth weight was indirectly associated to symptom severity via this factor. Conclusions These data indicate that birth weight is indirectly associated with ADHD severity via disruption of neuropsychological functions that are more primary in function as opposed to functions that play a higher-order role in utilising and integrating the primary functions.

Attention Deficit Hyperactivity Disorder Symptoms in Adults with Autism Spectrum Disorders / Kate JOHNSTON in Autism Research, 6-4 (August 2013)

To date, there has been a lack of research comparing attention in adults with ASD and adults with ADHD. In study 1, 31 adults with ASD and average intellectual function completed self-report measures of ADHD symptoms. These were compared with self-report measures of ADHD symptoms in 38 adults with ADHD and 29 general population controls. In study 2, 28 adults with a diagnosis of ASD were compared with an age- and intelligence quotient-matched sample of 28 adults with ADHD across a range of measures of attention. Study 1 showed that 36.7% of adults with ASD met Diagnostic and Statistical Manual-IV criteria for current ADHD “caseness” (Barkley Current self-report scores questionnaire). Those with a diagnosis of pervasive developmental disorder—not otherwise specified were most likely to describe ADHD symptoms. The ASD group differed significantly from both the ADHD and control groups on total and individual symptom self-report scores. On neuropsychological testing, adults with ASD and ADHD showed comparable performance on tests of selective attention. Significant group differences were seen on measures of attentional switching; adults with ADHD were significantly faster and more inaccurate, and individuals with Asperger's syndrome showed a significantly slower and more accurate response style. Self-reported rates of ADHD among adults with ASD are significantly higher than in the general adult population and may be underdiagnosed. Adults with ASD have attentional difficulties on some neuropsychological measures.

This study examines the influence of DDs on ADHD in a model-oriented approach that includes selectivity and intensity attention parameters. Methods:  Ten- to fifteen-year-olds with ADHD (n = 63), DDs (n = 61), ADHD+DDs (n = 64), and healthy controls (n = 64) completed a battery of tests including five neuropsychological tasks (i.e., alertness, sustained attention, divided attention, go/no-go, and attentional set-shifting). Results:  All clinical groups showed attentional problems, especially in more complex attentional tasks and in the intensity aspects of attention. We observed the most severe attentional impairments in children with ADHD that was independent from a comorbid DD. Conclusion:  The clinical groups were significantly different from the healthy control group, especially in more complex attentional tasks and in the intensity aspects of attention. Some differences between ADHD, DDs and ADHD+DDs groups were detected on neuropsychological attentional performance, but the effects were not strong enough to differentiate the clinical groups from each other.
