Impacts of adverse childhood experiences on individuals with autism spectrum disorder

Abstract

Individuals with autism spectrum disorder (ASD) are more likely to experience adverse childhood experiences (ACEs) compared with typically developing (TD) individuals, which predisposes them to an elevated risk of mental health issues. This review elucidates the profound impact of ACEs on individuals with ASD by synthesizing findings from a plethora of epidemiologic and biological studies, encompassing genetics, epigenetics, and neuroimaging. Despite the limited number of studies explicitly focusing on this intersection, the extant literature consistently demonstrates that ASD individuals are disproportionately affected by ACEs, leading to significant deterioration in mental health and brain function. Furthermore, the nature and extent of the effects of ACEs appear to diverge between ASD and TD populations, underscoring the necessity for tailored clinical and research approaches. Understanding these complex and intertwined interactions is imperative for advancing both clinical practice and research, with the goal of mitigating the adverse outcomes associated with ACEs in ASD individuals.
