Connections Between Prefrontal Cortex Anatomy and Autism Spectrum Disorder: A Literature Review.
📄 Abstract
This review examines the existing literature on the structural and functional changes in the anatomy of the prefrontal cortex (PFC) associated with autism spectrum disorder (ASD), focusing on the roles of molecular signaling disruptions and trace element imbalances. A literature review was performed through a structured search of academic publications from 2010 to 2025. Anatomic variations and structural and functional abnormalities within the PFC, including disruptions in neural connectivity, synaptic plasticity, and neurochemical balance, significantly contribute to the cognitive, social, and emotional deficits observed in ASD. The interplay between brain-derived neurotrophic factor dysregulation, oxidative stress, and trace element imbalances further exacerbates these dysfunctions. According to our findings, the anatomy of the PFC appears to play a crucial role in the pathophysiology of ASD, given its involvement in executive function, emotional processing, and social cognition, suggesting a multifactorial pathophysiology that demands a multidimensional research approach.
