VISUAL AND AUDITORY ALTERATIONS IN PEDIATRIC PATIENTS WITH ASD
Abstract
This study addresses visual and auditory alterations in children with Autism Spectrum Disorder (ASD) and their implications for language development and sensory integration. Through an integrative literature review, three main thematic categories were identified: (i) deficits in auditory processing, such as difficulties with temporal synchronization between visual and auditory stimuli; (ii) alterations in visual processing, with hyperactivation of the visual cortex and difficulties in perceiving relevant visual cues; and (iii) impaired audiovisual integration, which compromises the ability to combine sensory information. The findings indicate that these anomalies limit speech perception, attention, and social interaction, directly affecting language development. The study highlights the need for clinical interventions based on multisensory approaches that stimulate audiovisual integration, considering individual sensory profiles and the severity of symptoms.
