"Autism" describes a complex developmental disability that interferes with social interaction and communication. Symptoms of autism are generally recognizable when children are under the age of three. Until the 1990s, rates for autism were generally estimated at 1 in 2500. In 2010, however, the estimate is now 1 in 110 children. Is the incidence of autism increasing, or has there simply been a shift in how often this disability is diagnosed as the problem?
