Brain changes in autism are comprehensive throughout the cerebral cortex rather than specific areas thought to impact social behaviour and language, a new study has found.
THURSDAY, Nov. 3, 2022 (HealthDay News) -- Autism is a more comprehensive disorder than previously thought, and appears to arise from brain changes located throughout the cerebral cortex, not just
Brain changes associated with ASD encompass more areas than previously believed, a new study reports. Researchers identified brain-wide changes in all 11 cortical regions analyzed. The greatest gene drop-offs were found in the visual cortex and the parietal cortex, a brain area associated with processing touch, pain, and temperature information. The findings shed light on sensory hypersensitivity associated with ASD. Additionally, researchers say the RNA alterations associated with ASD are more likely a cause than a result of autism.
