Précis of Aging and Autism Spectrum Disorder: Evidence from the Broad Autism Phenotype by Wallace, Budgett, and Charlton
Summary:
Wallace, Budgett, and Charlton investigate the impact of the broad autism phenotype (BAP) on aging, focusing on its associations with executive function (EF), social support, and mental health in older adults. Using self-ratings from 66 individuals aged 61–88, the study compares those with elevated BAP traits to controls. Key findings reveal that BAP traits are linked to greater EF difficulties, reduced social support, and increased symptoms of depression and anxiety. The authors highlight the heightened risks for older adults with elevated BAP traits, emphasizing the need for further research to address the aging process in both BAP and autism spectrum disorder (ASD).
Key Findings:
1. Executive Function (EF) Deficits:
• Older adults with elevated BAP traits report significant EF impairments, particularly in behavior regulation and metacognitive domains, independent of age.
2. Social Support:
• Those with elevated BAP traits experience smaller social networks, fewer interactions, and less satisfaction with social relationships, increasing vulnerability to isolation and loneliness.
3. Mental Health:
• Elevated BAP traits correlate strongly with higher levels of depression and anxiety, suggesting compounded risks due to aging and social challenges.
4. Predictive Factors:
• Regression analyses identify social support as the strongest predictor of BAP traits, with EF deficits and depression also contributing significantly.
Implications:
The findings highlight the compounded risks faced by older adults with elevated BAP traits, including cognitive and social vulnerabilities. These results provide insights into aging in ASD and BAP, underscoring the importance of tailored interventions to mitigate risks and support well-being in older adulthood.
