Improvements in autism symptoms vary kid by kid

A new study suggests that social and communication skills in some kids with autism may improve over time with therapy, but other kids will continue having problems functioning as they get older.Not surprisingly, kids who had milder symptoms when they were first diagnosed tended to be doing better a few years later than those who started out with more severe autism.But among close to 7,000 children followed by researchers, there was also a group of so-called bloomers who started out with lots of communication and social problems but made fast gains during their elementary-school years.Theres a wide variety of children with different kinds of symptoms that fall within this (autism) umbrella, said Christine Fountain, the lead author of the study and an autism researcher at Columbia University in New York. We were interested in how these symptoms play out over time.The new findings, published Monday in Pediatrics, come just a few days after the Centers for Disease Control and Prevention released new data suggesting that one in 88 kids in the United States now has an autism spectrum disorder, which includes less-debilitating conditions such as Aspergers syndrome.Using data from California centers responsible for testing and treating kids with autism, Fountain and her colleagues tracked kids ages two to 14 whod had at least four evaluations. During those approximately annual evaluations, staff recorded kids symptoms of social and communication difficulties as well as their repetitive behaviors.The researchers found that especially when it came to social and communication scores, most kids improved over time -- though some much faster than others.White kids, and those whose parents were more educated, tended to have less severe autism symptoms during treatment. They were also more likely to be among the 10 percent or so of kids deemed bloomers, whose symptoms improved dramatically between ages three and 12.Kids who had other intellectual disabilities along with autism werent likely to have very large improvements. The conclusion is, if you have mental retardation as a co-occurring condition with autism, your prognosis is worse, said Johnny Matson, who studies autism spectrum disorders and intellectual disabilities at Louisiana State University in Baton Rouge.
