A study of 43 children with autism spectrum disorder indicated that, the more time required for an ASD individual to process auditory signals, the more severe that person’s autistic symptoms. “This is a first step toward developing a biomarker of autism severity—an objective way to assess someone’s place on the ASD spectrum,” said co-author Sophie Molholm. “Using EEG recordings in this way might also prove useful for objectively evaluating the effectiveness of ASD therapies.”
