Autism is a developmental disability that occurs to varying degrees in individuals who express characteristics of the disorder. Characteristics include difficulties with verbal and nonverbal communication, social interactions, and everyday activities and appear at a diagnosable level around the age of 2 years. The Autism Spectrum ranges from severe impairment to fully functioning. Researchers are currently investigating the potential causes of the disorder, including genetic and environmental factors. The incidence is currently thought to be 1 in every 100 to 150 births, as the rate has appeared to increase in the last few decades, along with better diagnostic tools.
