The differences are greatest in girls, in children aged 8 to 10 years, and in those with a low intelligence quotient (IQ) 1 . During typical development, the brain’s outer layer, called the cerebral cortex, thickens until about age 2 and then grows gradually thinner into adolescence as the brain matures. The new study, one of the largest to investigate cortical thickness in autism, aligns with others that indicate this trajectory differs in people with the condition. The findings suggest that brain structure does not change in a uniform way in autism, but instead varies with factors such as age, gender
