Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that is showing increasing prevalence worldwide. This rise is partly attributed to the expansion of diagnostic criteria and increased awareness efforts; however, the interaction between genetic predisposition and modern environmental factors is likely the primary reason behind the actual increase in prevalence.
Recent studies indicate that ASD is associated with early alterations in brain development beginning during the prenatal period, where genetic and environmental factors such as infections, gestational diabetes, and certain medications may affect the formation of neural networks in the fetal brain (Love et al., 2024).
Modern neuroimaging techniques have also been able to detect differences in neural connectivity among children with autism as early as six months of age, followed by an atypical pattern of brain growth during early childhood, with persistent neural connectivity deficits across developmental stages. This, in turn, affects communication skills, cognition, and social behavior in affected children. These findings highlight the importance of early detection and intervention based on a neurological understanding of the disorder (Rebecca A. Muhle et al., 2018).
Research has further demonstrated that fetal brain growth during the early stages of pregnancy may be associated with the emergence of early autistic traits in childhood, supporting the importance of early screening and developmental monitoring for children at risk (Aydin et al., 2024).
Additionally, recent neuroscientific studies have confirmed the presence of differences in brain regions responsible for communication and social interaction in individuals with ASD, along with ongoing disturbances in neural connectivity throughout different stages of development (Lamanna et al., 2024).
