Article: UC Davis MIND Institute: Atypical development in the siblings of children with autism is detectable at 12 months
This article discusses the results of a 2014 study, published by researchers with the UC Davis MIND Institute and UCLA. The study found that close to half of the younger siblings of children with ASD develop in an atypical fashion. It is estimated that 17 percent of younger siblings develop ASD and 28 percent show delays in areas of development or behavior. Among siblings, these delays can be detected as early as 12 months of age.
