Researchers found the brains of children living with autism were larger than those of their peers without the disorder.

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.
