Why are some people with autism hypersensitive to sound?

(University of California - Riverside) The University of California, Riverside has received a grant from the National Institutes of Health to study the mechanisms of auditory hypersensitivity -- an increased sensitivity to sound through a negative emotional response -- in Fragile X syndrome (FXS). The five-year $8.7 million grant is awarded to UC Riverside and the University of Texas Southwestern Medical Center, Dallas. FXS is the most common inherited cause of intellectual disability and the most common cause of autism.
