There has been a dramatic rise in the number of autism cases in the United States. About 1 in every 110 children is diagnosed with autism. It is not surprising that the causes of this rise are unknown due to the nature of the disorder. Children with autism are very different from each other. There is a multitude of disorders under the umbrella that we call autism spectrum disorders. The one thing that researchers and epidemiologists are confident about is the lack of correlation between autism and vaccinations. According to researchers and epidemiologist at the M.I.N.D. institute, autism probably has a number of genetic and environmental causes, but current vaccinations have not statistically shown correlation to autism cases. While there are more that 20 different genes said to be connected with autism, each of those only effects about 1- 2% of the autistic population. On the other hand, an opposing hunch is that lots of things that are environmentally overwhelming our ability to cope metabolically, thus depleting our protective systems and, perhaps, causing autism. The truth remains to be seen.
