IQ is generally expected to remain stable over time, but new research suggests that the measure increases significantly for those with autism during adolescence and early adulthood.

In a long-term study of 126 people on the spectrum, IQ scores increased by an average of 7.48 points between the ages of 12 and 23. During the same period, autism symptoms in those studied remained unchanged.

The findings published Friday in the Journal of the American Academy of Child and Adolescent Psychiatry looked at children who were part of the UK Special Needs and Autism Project, which periodically followed up with a group of kids on the spectrum in England to assess how they changed.
