Autism is on the rise, but is it due to inheritance or to lifestyle? This seems to be the burning question of the day, as many new insights into the cause of autism are unfolding.
Autism encompasses a range of disorders, from mild to profound mental retardation, and social ineptitude often including repetitive and aggressive behavior. Signs and symptoms of autism are noticed in the first one to three years of a child's life. As many as 1 in 150 children, or up to 1.5 million people, in the US are affected. Currently there is no cure.
