Washington, Jan 9 (ANI): Scientists have found that children with autism spectrum disorders (ASDs) process sound and language a fraction of a second slower than those without ASDs.
And measuring magnetic signals depicting this delay may become a standardized way to diagnose autism, say researchers at The Children's Hospital of Philadelphia.
"More work needs to be done before this can become a standard tool, but this pattern of delayed brain response may be refined into the first imaging biomarker for autism," said study leader Dr. Timothy P.L. Roberts, vice chair of Radiology Research at Children's Hospital.
ASDs are a group of childhood neurodevelopmental disorders that cause impairments in verbal communication, social interaction and behavior.
If researchers can develop imaging results into standardized diagnostic tests, they may be able to diagnose ASDs as early as infancy, which could lead to possible earlier intervention with treatments.
This could also enable them to differentiate types of ASDs (classic autism, Asperger's syndrome or other types) in individual patients.
In the current study, the researchers used magnetoencephalography (MEG), which detects magnetic fields in the brain, similar to the way electroencephalography (EEG) detects electrical fields.
