Impaired Sensory Integration in Autism

Researchers from Albert Einstein Medical Center have found that sensory integration (sound and vibration) are abnormally integrated in children with autism. Not only do sound and vibration fail to summate as in typically developing children, but for children with autism, there is a pronounced delay in the arrival of sensory stimuli to the the cortex (measured by EEG).

Excerpt:

"This was a much-needed study of multisensory integration in autism," said Barry E. Stein, Ph.D., professor and chair of neurobiology & anatomy at Wake Forest University School of Medicine, who was not involved in the Einstein study. "Using simple logic and standard techniques for electrically mapping the brain, the authors have identified defects in the way ASD individuals synthesize cues from different senses. In doing so, they have not only helped confirm the insights of parents
and clinicians, but they've improved our understanding of how the behavioral differences in children with ASD may result from sensory anomalies."

Hooray, this information has been a long time coming for parents, professionals, children, and adults with autism. Hopefully it will help provide more objective support that therapeutic interventions help the disabling effects of sensory processing impairment.
