What causes autism?

The causes of autism are not known, many attribute the disorder to genetic factors because it runs in the family. It is believe that some children are more prone than others to be autistic because it has to do with the way that the brain develops and how the cells communicate among each other. Another theory is pollutants in the air are the one to blame for autism and kids and for these reasons the environment in which the kid live in has a lot to do with the phenomenon.

Another big theory is the vaccine.The mercury in the measles-mumps-rubellahttp://mayoclinic.com/health/autism is being blamed for the disorder, but researchers do not agree with the theory and more research are being done in these aspect.

All of these are just theory, no one knows for sure what the real cause is. Perhaps is a combination of factors involve in it. What is for sure is that the makers of the vaccine are not going to come forward and say that the mercury is the real problems, why? Money says all and they are not willing to lose their big business over it. The key is research and more study in the field.
