As children with autism age, services to help with transition needed Posted: 20 Dec 2016 07:40 AM PST One in 45 children is diagnosed with autism. As these children age, experiences such as leaving school, finding jobs and living alone can be stressful for adolescents with autism as well as their caregivers. Researchers have conducted the first study analyzing the perspectives of adolescents with autism to identify challenges as they "age out" of services. The researchers say these findings highlight the need for social workers and providers to assist children with autism as they transition to adulthood.
