Unique brain wave patterns, spotted for the first time in autistic children, may help explain why they have so much trouble communicating.
Using an imaging helmet that resembles a big salon hair dryer, researchers discovered what they believe are "signatures of autism" that show a delay in processing individual sounds.
That delay is only a fraction of a second, but when it's for every sound, the lag time can cascade into a major obstacle in speaking and understanding people, the researchers said.
Imagine if it took a tiny bit longer than normal to understand each syllable. By the end of a whole sentence, you'd be pretty confused.
The study authors believe that's what happens with autistic children, based on the brain wave patterns detected in school-age children in their study.
