Causes. There is no known single cause for autism spectrum disorder, but it is generally accepted that it is caused by abnormalities in brain structure or function. Brain scans show differences in the shape and structure of the brain in children with autism compared to in neurotypical children.
We now know that there is not one autism but many types, caused by different combinations of genetic and environmental influences. The term âspectrumâ reflects the wide variation in challenges and strengths possessed by each person with autism. Autismâs most-obvious signs tend to appear between 2 and 3 years of age. In some cases, it can be diagnosed as early as 18 months. Some developmental delays associated with autism can be identified and addressed even earlier.
