Children diagnosed with Autism Spectrum Disorder (ASD) show impairments in gaze-following and will seldom engage in joint attention (JA). The ability to initiate JA (IJA) can be more impaired than the ability to respond to JA (RJA). In a longitudinal study, 101 high-risk infants for ASD (62% males) completed MRI scans at 4 or 6 months of age. Subcortical volumes (thalamus, basal ganglia, hippocampus, amygdala) were extracted. Gaze and JA behaviours were assessed with standardized measures. The majority of infants were IJA non-responders (n=93, 92%), and over half were RJA non-responders (n=50, 52%). In the non-responder groups, models testing the …

Children with Autism Spectrum Disorder (ASD) are statistically more likely to experience early adversity; however, little is known about which types of adversity are most prevalent, the role of parenting as a protective factor, and how this early life stress impacts cognitive outcomes. We assessed adversity and parenting styles in 238 children (ASD=82) aged 6–16 years using parent report. Intellectual abilities were assessed using the WISC-V. Children with ASD had increased incidence of familial stressors compared to Typically Developing (TD) children. Positive parenting was associated with significant decreases in familial adversity for all children. Environmental stressors were associated with cognitive …
