Green Treehouse

What causes Autism? That’s what parents, doctors, and researchers want to know. Thanks to a new study we may be closer to answers. Researchers at Cornell University have found that “children growing up in the rainiest or snowiest areas of the country seem to have a higher risk for autism than children living in drier climates.”

The latest thinking is that precipitation increases exposure to mercury and other dangerous neurotoxins through deposition in the environment. It’s suspected that this exposure to outdoor and indoor neurotoxins triggers a genetic predisposition to Autism Spectrum Disorders (ASD). Recent studies have also shown increases in mercury levels in Americans in recent years, which support this latest reports’ findings.
