Autism is such a tough thing for children. They often have trouble with social interaction and communication with others.
how any people have autism?
I am not sure the exact number, but enough that there was a advocacy organization in the United States started called "Autism Speaks" to conduct research and awareness.
thats good to know. how long has autism been identifed as an issue ?
I believe in the early 1900's and there is no known cure.
what causes it ?
It is caused by a combination of genetic and environmental factors.
that makes sense
