This study aimed to complete a 5-year follow-up of children with high-functioning autism (HFA) who previously lacked the normal age-OI association; and compare unirhinal-OI in children with HFA, Asperger’s disorder (ASP), and controls. While both HFA and controls had improved birhinal-OI at follow-up, reduced OI in some HFA participants suggested OFC deterioration and heterogeneous OFC development. Unirhinal-OI was impaired in HFA but not ASP relative to controls, suggesting orbitofrontal compromise in HFA but integrity in ASP. Differing IQ-OI relationships existed between HFA and ASP. Findings support the hypothesis of separate neurobiological underpinnings in ASP and HFA, specifically differential orbitofrontal functioning.

Hierarchical linear modeling results revealed that marital adjustment mediated associations between positive perceptions and maternal well-being. Mothers who reported higher levels of positive perceptions of the child were higher in marital adjustment and well-being. Results also revealed that marital adjustment moderated the relation between negative perceptions and negative maternal affect. Mothers low in marital adjustment had a positive association between negative maternal perceptions of the child and negative maternal affect. These findings highlight the dynamic roles that mothers’ perceptions and marital adjustment play in determining maternal psychological outcomes.

Contrary to our expectations, the disorder groups did not outperform the neurotypical group in the neuropsychological measures of local information processing. In line with our hypotheses, the self-reports did show higher levels of local information processing and a stronger tendency to use systemizing strategies in the two disorder groups. Absent and weak correlations were found between the self-reports and the two neuropsychological tasks in the three groups. The neuropsychological tests and the self-reports seem to measure different underlying constructs. The self-reports were most predictive of the presence of an autism spectrum diagnosis.

The model comprises four elements: parental stress, parental resources, parental adjustment and the child’s autism symptoms. 176 parents of children aged between 6 to 16 diagnosed with PDD answered several questionnaires measuring parental stress, personal resources (sense of coherence, locus of control, social support) adjustment (mental health and marriage quality) and the child’s autism symptoms. Path analysis showed that sense of coherence, internal locus of control, social support and quality of marriage increase the ability to cope with the stress of parenting an autistic child. Directions for further research are suggested.

Diagnoses of autism were identified from administrative databases with relevant diagnostic information to 2005. A factor representing genetic susceptibility was defined as having an affected sibling or a mother with a history of a psychiatric or neurologic condition. Among 129,733 children, there were 924 children with an autism diagnosis. The results suggest that among those with low genetic susceptibility, some maternal and obstetric factors may have an independent role in autism etiology whereas among genetically susceptible children, these factors appear to play a lesser role. The role of pre-pregnancy obesity and excessive weight gain during pregnancy on autism risk require further investigation.

Previous studies have found evidence of a double dissociation between the disorders on specific executive functions (planning and response inhibition). To date most research has been conducted with children. No studies have directly compared the stable cognitive profile of adults. It was hypothesised that adults with ASD would show generally intact response inhibition whereas those with ADHD would show more global impairment. Participants were 24 adults aged 18–55 with high functioning ASD, 24 with ADHD, and 14 age and IQ matched controls. Participants completed three standardised measures of response inhibition. Participants with ASD had generally intact response inhibition but slow response latencies, possibly due to deficits in response initiation. Adults with ADHD did not show the more global impairments hypothesised. There were some significant differences between the clinical groups across measures of inhibition. In terms of performance style, adults with ASD were slow and accurate whilst those with ADHD showed an impulsive style.

Prevalence was high, with parents reporting that 68% had demonstrated aggression to a caregiver and 49% to non-caregivers. Overall, aggression was not associated with clinician observed severity of ASD symptoms, intellectual functioning, gender, marital status, parental educational level, or aspects of communication. Individuals who are younger, come from a higher income family, have more parent reported social/communication problems, or engage in repetitive behaviors were more likely to demonstrate aggression. Given the significant impact of aggression on individual and family outcomes, it is hoped that this knowledge will inform more targeted intervention efforts.

Case–control comparisons revealed a significantly higher frequency of the low-activity 677T allele, higher prevalence of the 677TT genotype and higher frequencies of the 677T-1298A haplotype and double homozygous 677TT/1298AA genotype in affected individuals relative to controls. Family-based association testing demonstrated significant preferential transmission of the 677T and 1298A alleles and the 677T-1298A haplotype to affected offspring. The results were not replicated in MPX families. The results associate the MTHFR gene with autism in SPX families only, suggesting that reduced MTHFR activity is a risk factor for autism in these families.

Case–control comparisons revealed a significantly higher frequency of the low-activity 677T allele, higher prevalence of the 677TT genotype and higher frequencies of the 677T-1298A haplotype and double homozygous 677TT/1298AA genotype in affected individuals relative to controls. Family-based association testing demonstrated significant preferential transmission of the 677T and 1298A alleles and the 677T-1298A haplotype to affected offspring. The results were not replicated in MPX families. The results associate the MTHFR gene with autism in SPX families only, suggesting that reduced MTHFR activity is a risk factor for autism in these families.

Do High-Functioning People with Autism Spectrum Disorder Spontaneously Use Event Knowledge to Selectively Attend to and Remember Context-Relevant Aspects in Scenes? / Eva LOTH in Journal of Autism and Developmental Disorders, 41-7 (July 2011)

Type de document : Texte imprimé et/ou numérique Auteurs : Eva LOTH, Auteur ; Juan-Carlos GOMEZ, Auteur ; Francesca HAPPE, Auteur Année de publication : 2011 Article en page(s) : p.945-961 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Top-down processes  Event schemas  Gaze-tracking  Memory Index. décimale : PER Périodiques Résumé : This study combined an event schema approach with top-down processing perspectives to investigate whether high-functioning children and adults with autism spectrum disorder (ASD) spontaneously attend to and remember context-relevant aspects of scenes. Participants read one story of story-pairs (e.g., burglary or tea party). They then inspected a scene (living room) of which some objects were relevant in that context, irrelevant (related to the non-emphasized event) or neutral (scene-schema related). During immediate and delayed recall, only the (TD) groups selectively recalled context-relevant objects, and significantly more context-relevant objects than the ASD groups. Gaze-tracking suggests that one factor in these memory differences may be diminished top-down effects of event schemas on initial attention (first ten fixations) to relevant items in ASD.

The present study examined distributions of attachment security and disorganization at 15-months of age in a sample of infant siblings of older children with (ASD-sibs; n = 51) or without (COMP-sibs; n = 34) an ASD. ASD-sibs were not more or less likely to evince attachment insecurity or disorganization than COMP-sibs. However, relative to COMP-sibs, the rate of B1–B2 secure subclassifications was disproportionately larger in the ASD-sib group. Results suggest that ASD-sibs are not less likely to form secure affectional bonds with their caregivers than COMP-sibs, but may differ from COMP-sibs in their expression of attachment security.

Brief Report: Developing Spatial Frequency Biases for Face Recognition in Autism and Williams Syndrome / Hayley C. LEONARD in Journal of Autism and Developmental Disorders, 41-7 (July 2011)

Typically-developing children and groups with Williams syndrome and autism were asked to recognise faces in which low, middle and high spatial frequency bands were masked. All three groups demonstrated a gradual specialisation toward the mid-band. However, while the use of high spatial frequencies decreased in control and autism groups over development, the Williams syndrome group did not display a bias toward this band at any point. These data demonstrate that typical outcomes can be achieved through atypical developmental processes, and confirm the importance of cross-syndrome studies in the investigation of developmental disorders.
