RICHMOND, VA (NBC12) - Researchers may have found a way to detect autism by analyzing brain waves. They recorded electrical currents in the brains of both autistic children and those without the condition.
They gave both groups different types of audio stimulation like tones, beeps, vowels and sentences -- then gave them at different frequencies.
Autistic children showed a fraction of a second delay in the brain's response to some of the sounds.
