Autism

**__What causes Autism?__**
The exact causes of Autism are unknown to scientists. They however believe that genetic factors are important.

The cause is a topic being researched a lot. Some other causes that scientists have considered __but not proven__ are:
 * diet
 * digestive trait changes
 * mercury poisoning
 * the bodies inability to properly use vitamins and minerals
 * vaccine sensitivity
