Public ISBD [article]  inResearch in Autism Spectrum Disorders > 54 (October 2018) . - p.27-36 Titre : Aging with elevated autistic traits: Cognitive functioning among older adults with the broad autism phenotype Type de document : Texte imprimé et/ou numérique Auteurs : Gavin R. STEWART, Auteur ; Rebecca A. CHARLTON, Auteur ; Gregory L. WALLACE, Auteur Article en page(s) : p.27-36 Langues : Anglais (eng) Mots-clés : Aging  Broad autism phenotype  Executive function Index. décimale : PER Périodiques Résumé : Background Little is known about the impact of aging with autism spectrum disorder (ASD) on cognition. As a first step in addressing this gap in our knowledge, the current study examined cognitive functioning among older adults with elevated, but subclinical levels of autistic traits (i.e., the Broad Autism Phenotype; BAP) compared to older adults without the BAP. Method Forty older adults (aged 60–91, M?=?73 years) were recruited and classified as meeting criteria for the BAP (n?=?20) or not (control older adults, COA; n?=?20). Different components of executive function as well as episodic memory were measured using standardized performance-based neuropsychological assessments in addition to a self-report questionnaire of executive function difficulties. Results Despite no differences in age, sex ratio, educational history or IQ, the BAP group demonstrated poorer performance on measures of executive function and episodic memory compared to the COA group. The BAP group also self-reported more executive function difficulties in everyday settings. Moreover, differences in working memory and attentional shifting were maintained after accounting for the influences of IQ and both depression and anxiety symptoms. Conclusions These findings suggest that aging with the BAP confers additional risk to cognitive function for older adults. As the BAP forms a bridge in the continuum from typical to atypical levels of autistic traits, these findings suggest that individuals with ASD might also incur cognitive costs as they age into older adulthood.

Dans cet article de synthèse, nous nous concentrons sur plusieurs domaines où notre compréhension de l'autisme a changé : 1. d’une définition « étroite » à des critères diagnostiques « larges » ; 2. d'une condition rare à une condition relativement courante, bien que probablement encore sous-reconnue chez les femmes et les personnes âgées; 3. d'une condition diagnostiquée principalement chez les hommes à une identification, désormais, chez les personnes de tous genres ; 4. d'un état qui touche les enfants à une condition tout au long de la vie; 5. d'une manifestation discrète et distincte à une vision dimensionnelle; 6. d'une seule entité à de nombreux « autismes », et une condition composite ou fractionnable ; 7. d'une focalisation sur l'autisme « pur » à a reconnaissance que la complexité et la comorbidité sont la norme ; 8. de la conceptualisation de l'autisme uniquement comme un trouble du développement à la reconnaissance d'une perspective de neurodiversité, opérationnalisée dans des modèles de recherche participative. Nous explorons également les opportunités pour que la recherche devienne plus généralisable, y compris clans un contexte mondial, et formulons des suggestions pour des domaines actuellement négligés dans la recherche sur l'autisme.

Self-harm and Suicidality Experiences of Middle-Age and Older Adults With vs. Without High Autistic Traits / Gavin R. STEWART in Journal of Autism and Developmental Disorders, 53-8 (August 2023)

Elevated autistic traits have also been associated with higher rates of self-harm, suicidal ideation, and suicidal self-harm in the general population, but this has yet to be examined in older age. Using baseline cross-sectional data from the PROTECT study, middle-age and older adults with high autistic traits (n?=?276) had significantly higher rates of suicidal ideation, deliberate self-harm, and suicidal self-harm than an age/sex-matched comparison group (n?=?10,495). These differences represented a 5- to 6-fold increase in likelihood for self-harming and suicidality. These findings, which remained when controlling for depression symptoms, suggest that middle-age and older adults with high autistic traits may be particularly at risk of self-harm and suicidal behaviours.

Sleep problems and mental health difficulties in older adults who endorse high autistic traits / Gavin R. STEWART in Research in Autism Spectrum Disorders, 77 (September 2020)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 77 (September 2020) . - 101633 Titre : Sleep problems and mental health difficulties in older adults who endorse high autistic traits Type de document : Texte imprimé et/ou numérique Auteurs : Gavin R.

However, these problems have seldom been studied in older autistic adults, or in older adults with elevated autistic traits. Method Cross-sectional data was examined from 13,897 adults aged 50–81 years taking part in the PROTECT study, who reported whether they experienced persistent socio-communicative autistic traits. Approximately 1%, 187 individuals, were identified as endorsing high autistic traits in childhood and currently, henceforth ‘Autism Spectrum Trait’ (AST) group. An age- and gender-matched comparison group was formed of 6740 individuals who endorsed no autistic traits, henceforth ‘Control Older Adults’ (COA) group. Differences between AST and COA groups were explored in self-reported sleep behaviors, and in depression and anxiety symptoms. Results AST and COA groups reported similar sleep duration and depth, and nighttime waking frequency. However, the AST group reported significantly more problems with falling asleep, morning drowsiness, and lower sleep quality/satisfaction than COA. More AST adults reported sleep problems past cut-off, as well as clinical levels of depression and anxiety, compared to COA. Adults in both groups who met criteria for high sleep problems experienced more mental health difficulties than those with few sleep problems. However, even amongst those without depression/anxiety, the AST group reported more sleep problems than the COA. Conclusions These associations suggest that older adults with high autistic traits, like diagnosed autistic children/young adults, may experience poorer sleep and more mental health difficulties than those with low autistic traits. Further work is needed to see whether these results extend to older individuals meeting diagnostic criteria for autism.
