Autism spectrum disorder (ASD) affects children’s social and intellectual development. Conventional diagnostic methods for ASD rely on behavioral observation. Researchers have now identified a potential quantifiable biomarker for diagnosing ASD. Using magnetic brainwave imaging, they correlated altered gamma oscillation with the motor response of children with ASD, which is consistent with previous key hypotheses on ASD. The means of observation potentially offers a noninvasive, impartial form of early diagnosis of ASD.
