social interactions.  The disorder makes it hard for them to communicate with others and 
relate to the outside world.  In some cases, aggressive and/or self-injurious behavior may 
be present.  Persons with autism may exhibit repeated body movements (hand flapping, 
rocking), unusual responses to people or attachments to objects and resistance to changes
