Diagnostic history and treatment of school-aged children with autism spectrum disorder and special health care needs.

Data from the 2011 Survey of Pathways to Diagnosis and Services The median age when school-aged children with special health care needs (CSHCN) and autism spectrum disorder (ASD) were first identified as having ASD was 5 years. School-aged CSHCN identified as having ASD at a younger age (under age 5 years) were identified most often by generalists and psychologists, while those identified later (aged 5 years and over) were identified primarily by psychologists and psychiatrists. Nine out of 10 school-aged CSHCN with ASD use one or more services to meet their developmental needs. Social skills training and speech or language therapy are the most common, each used by almost three-fifths of these children. More than one-half of school-aged CSHCN with ASD use psychotropic medication.
