Researchers from the University of North Carolina looked at children living with /*autism*/ by the age of 2. They found their brains were up to 10 percent larger than 2-year-olds without the disorder.
The study also showed the larger brains were the result of accelerated brain growth around the children's first birthday.
Researchers said the findings could lead to a better understanding of the genes that cause autism and earlier identification and treatment of the disorder.
