New Autism Regression Research Looks Promising for Diagnosis

It has always been thought that there are two clear types of autism: One that exists from the time a child is born and then another that shows up in toddlers out of nowhere. Classic autism signs show up in newborns around milestones that may be missed. For example, a typical 9-month-old will be able to respond to his/her name when a parent says it by actions such as turning their head. Children with autism are unable to make the connection and respond adequately. Another sign is the child may not start cooing or babbling. These children often have trouble forming relationships and may often prefer to play by themselves. In the regression type of autism, this is very different. An infant will develop in typical ways. The child will be able to express themselves verbally and enjoy being silly with parents. They play with others and seem like the average child. Signs can show up abruptly in these cases from toddler to preschool years. The once playful, talkative, social child suddenly begins to lose these skills and gain typical traits of autism. Were there signs at an earlier age that may have pointed to the condition? What used to be viewed as two clear types is changing with new research.
