Are Autistic People Smarter?

Intelligence tends to increase in half of autistic kids between the age 2 and 8.
Findings indicate that intelligence quotient is unstable in young autistic children, and it seems to stabilize usually about age 5.
“This tells us that you can’t be too hasty in diagnosing intellectual disability, because you just don’t know what’s going to happen,” states Marjorie Solomon, professor at the University of California, Davis.
Solomon and colleagues examined data from The Autism Phenome Project, which is a lengthy study of kids diagnosed with ASD. They analyzed the IQ scores for 102 children, 20 being girls, at the ages of 2 or 3, and once more at ages 6 to 8.
They identified 4 groups of children based on how their IQs evolved over that period. While the high challenges’ group began with IQs about 44 and dropped a little to 36, the stable-low group began with a bit higher IQs that remained stable.
The 2 other groups demonstrated IQ increases: the lesser challenges’ group began with average IQs which went up to scores averaging 111 over time, and the changers’ group began with IQ below 70 which rose significantly over time.
