Autism impacts each person differently, depending on the person and the severity of the autism. Some people are very high-functioning, and others are not capable of handling daily tasks. You can support autism by raising awareness and by allowing autistic people to do as much as possible to contribute to their own care. Sources like AutismScienceFoundation.org and Kidshealth.org can provide you with a lot of good information about the impact of autism on individuals, families, and society.
