| Autistic boys and men show notable differences in brain development, according to magnetic resonance imaging scans taken over a 16-year period. The results, published in NeuroImage in April, build on an eight-year study of some of the same people and add two more time points to the previous three. “With the addition of these time points, we now see that these non-uniform regional volumetric differences really persist into very late childhood,” says co-lead investigator Brandon Zielinski, associate professor of pediatrics and of neurology at the University of Utah in Salt Lake City. He and his colleagues scanned the brains of 105 autistic and 125 non-autistic boys and men at up to five time points from 2003 to 2019. Participants ranged in age from 6 to 45 years at the first scan. Although the researchers recruited some new participants over the course of the study, 73 percent of the original autistic participants and 50 percent of controls underwent all five scans. |
