Autism is one of the most frequent pediatric disorders. More and more children are diagnosed with this disorder of brain development that appears before three years of age and that deteriorates their communication and social interaction causing restricted and repetitive behavior.
Among the great unknowns about autism are its true cause (if there is only one) and if it has a cure. At the moment, we cannot answer these questions, but scientists are still investigating what are the factors that predispose it to try to find its origin.
They look in all directions, even in heaven, as a study by American researchers at Cornell University states that Autism has a higher prevalence among children who lived during the first three years of their life in a rainy area of the country like California, Oregon and Washington.
They suggest that maybe, children who live in places where it rains a lot spend more time inside the house in front of the TV and this generates brain changes. Maybe indoors they breathe more harmful chemicals or they may not receive the necessary amount of vitamin D, the sun's vitamin.
They also speculate that chemicals in the upper part of the atmosphere can be transported to the earth's surface through rain or snow, which would reinforce the hypothesis of environmental factors related to the disease.
This does not mean that we have to move to populations with a drier climate during childhood. These studies should not be taken to the letter, in fact it is a childhood disorder that is increasing in all climates, but they do help to open new lines of research to discover the riddles of autism.
