Disruption of Embryogenesis Biomarkers: A Critical Issue for Autism Therapeutics

Abstract

Recent advancements in the field of autism research have led to significant progress in identifying biomarkers associated with autism spectrum disorder (ASD). This article provides a comprehensive update on the current landscape of biomarkers, encompassing genetic, neurobiological, and behavioral indicators. Genetic studies have identified numerous candidate genes and chromosomal abnormalities linked to ASD, highlighting the heritable nature of the disorder. Neuroimaging techniques, including functional magnetic resonance imaging (MRI) and diffusion tensor imaging, have revealed distinct patterns of brain connectivity and structural anomalies that correlate with ASD symptoms. Additionally, electrophysiological measures, such as event-related potentials and electroencephalography, offer insights into the neural mechanisms underlying social cognition and sensory processing in individuals with autism. Emerging research on metabolic and inflammatory biomarkers also shows promise in elucidating the biological pathways involved in ASD. Although these findings provide valuable avenues for early diagnosis and personalized treatment strategies, challenges remain in translating biomarker research into clinical practice. This review emphasizes the need for continued exploration of biomarkers to enhance our understanding of ASD and improve diagnostic accuracy and intervention efficacy for affected individuals.
