Autism Spectrum Disorders (ASDs) encompass a set of neurodevelopmental conditions marked by challenges in social interaction, communication, and by restricted or repetitive behaviors, with their etiology linked to atypical brain network patterns. Non-Invasive Brain Stimulation (NIBS) has been shown to influence cerebral cortex activation and reorganize brain networks in individuals with ASDs, leading to improvements in behavioral symptoms. This review explores the impact of two brain stimulation methods, Transcranial Magnetic Stimulation (TMS) and Transcranial Direct Current Stimulation (tDCS), on behavior, cognitive functions, and speech in patients with ASDs, and assesses the potential for clinical applications of NIBS.
