If someone has autism, his or her brain has trouble with an important task; that is making sense of the world. Each day, your brain interprets the sights, sounds and other stimuli. If your brain couldn't help you understand these things, you would have trouble functioning, talking, going to school, and doing other everyday stuff.
Sadly there is no cure for autism, but doctors, therapists, and special teachers can help children with autism overcome or adjust to many difficulties. The earlier a child starts treatment for autism, the better.
Some children with mild autism will grow up and be able to live on their own. Those with more serious problems will always need some kind of help. All children with autism have brighter and happier futures when they have the support and empathy of doctors, teachers, caregivers, parents, brothers, sisters, and friends.
