Scans Show Sound-Processing Deficits in Autistic Kids

ear

MONDAY, Dec. 1 (HealthDay News) -- Children with autism spectrum disorder process sounds a fraction of a second slower than other children, an abnormality that offers insight into listening and language issues linked to the condition, a new study says.

Researchers used magnetoencephalography (MEG), which records minute magnetic fields associated with electrical brain activity, to detect the slight delay in autistic children who were exposed to beeps, tones in pairs, vowels and sentences at different speeds, tones and frequencies.

The findings were expected to be presented Monday at the annual meeting of the Radiological Society of North America (RSNA), in Chicago.
