| More than half of people with autism in the United States have an average or above-average intelligence quotient (IQ), an uptick over previous estimates, a new longitudinal study of children in Minnesota suggests. The rise could reflect a heightened awareness and understanding of the condition, as well as improvements in recognizing and detecting it, says lead investigator Maja Katusi, a developmental pediatrician at the Mayo Clinic in Rochester, Minnesota. In 2016, the proportion of autistic children in the U.S. with an average or higher IQ was 42 percent, according to the most recent autism prevalence data published by the Centers for Disease and Control and Prevention (CDC) in 2020. |
