NBC News (10/1, Szabo) reports a genetic analysis found “that people with autism spectrum disorder diagnosed in late childhood or adolescence actually have ‘a different form of autism,’ not a less severe one.” Senior author Dr. Varun Warrier, an autism researcher at the University of Cambridge, explained that “the ‘genetic profile’ of people with late-diagnosis autism actually looks more like depression, attention-deficit/hyperactivity disorder and post-traumatic stress disorder than early childhood autism.” The study suggests that some children with autism “develop differently and may not receive a diagnosis earlier on because their features may not yet have clearly emerged,” Warrier said. Overall, experts believe the study “illustrates that autism is not a single condition with one root cause, but rather an umbrella term for a cluster of conditions with similar – although not identical – features.” The study was published in Nature.
