A new study reveals how certain genetic mutations linked to autism spectrum disorder may also influence brain development in ways that could explain heightened sensory sensitivities often reported by individuals on the spectrum. Researchers examined neural pathways associated with processing sensory information, finding distinct differences in how these regions form and function compared to neurotypical development. The findings suggest potential biological roots for why some people with autism experience overwhelming reactions to sounds, textures, or light. Experts caution that while the research offers valuable insights, more work is needed to translate these discoveries into practical support for affected individuals.
