About Autism
Autism spectrum disorders (ASDs) are a group of
developmental disabilities defined by significant
impairments in social interaction and communication
and the presence of unusual behaviors and interests.
Many people with ASDs also have unusual ways of
learning, paying attention, or reacting to different
sensations. The thinking and learning abilities of
people with ASDs can vary – from gifted to severely
challenged. ASD begins before the age of 3 and lasts throughout a
person's life. It occurs in all racial, ethnic, and
socioeconomic groups and is four times more likely
to occur in boys than girls.
