Researchers have found a new test that will help in determination of Autism in early period in children’s life. According to this research the respond to pleasant and unpleasant odors can help to identify are the children suffering from autism spectrum disorder. This research has shown that the people with autism spectrum disorder do not make the natural adjustment like other people in the case when they encounter unpleasant smell.
The difference in sniffing pattern between the typically developing children and children with autism was simply overwhelming,’ said Noam Sobel of the Weizmann Institute of Science in Israel, the leader of this study. He also added that he can identify autism and its severity with meaningful accuracy within less than 10 minutes, using a test that is completely non-verbal and entails no task to follow.
For this study is created a “computer-controlled air-dilution olfactometer” fortified with a pediatric nasal cannula. The study was conducted in 18 children with ASD and 18 normally developing children. The average age of children in the study was seven. While typical children adjusted their sniffing within 305 milliseconds of smelling an odor, children on the autism spectrum showed no such response, the researchers reported. That difference in sniff response between the two groups of kids was enough to correctly classify them as children with or without a diagnosis of ASD 81 percent of the time.
Autism has become the fastest growing development disorder in the U.S., where one in 68 children has been diagnosed with autism, the majority of who are males.
It is believed that this approach will be more comprehensive for medical testing for autism.
