Neural Basis of Sense of Space in Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a complex developmental disorder marked by variations in cognitive development, with challenges in spatial cognition and navigation. The rise in ASD diagnoses has led research to focus on understanding how changes in neuroanatomy influence the way individuals with ASD perceive and process spatial information. This paper investigates how changes in key brain regions impacts spatial navigation in individuals with ASD. Through a synthesis and analysis of relevant literature, the study shows that spatial perception in individuals with ASD is closely associated with functional changes in these brain regions. The hippocampus is vital for encoding spatial information and forming memories, while the parietal-occipital regions are crucial to spatial localization and visual processing. Moreover, individuals with ASD often rely more on local processing, impairing navigational abilities in dynamic environments. In short, the analysis suggests that interventions like Sensory Integration Training (SIT) can improve spatial cognition and enhance spatial navigation abilities in individuals with ASD.
