You would probably be surprised at the number of people who have children with autism and asperger syndrome.  It can be very difficult, not only for the person is suffering from the disorder but for those that have to take care of them as well.  There are several ways that you can show your support for these individuals.  For example, you can buy T-shirts that help to raise awareness of autism or you may put a bumper sticker on your car.  It might seem like rather simple things that you can do but any time that you raise awareness of the disorder, it helps the cause.
