Symptoms of autism usually appear during the first three years of childhood and continue throughout life. Although there is no cure, appropriate management may foster relatively normal development and reduce undesirable behaviors. People with autism …

…and how these characteristics change over time. The findings may lead to improved strategies for early diagnosis and intervention. Related studies are examining how the cerebellum develops and processes information, how different brain regions function in relation to each other, and how alterations in this relationship during development may result in the signs and symptoms of autism. Researchers hope this research will provide new clues about how autism develops and how brain abnormalities affect behavior.
