Big surges in new autism diagnoses among young adults, as well a rise in diagnoses for girls and young women, have driven a near-tripling of U.S. autism cases in just over a decade, researchers report.
Data on over 12 million patients enrolled in major U.S. health care systems found that between 2011 and 2022 the number of people diagnosed with autism climbed by 175%, according to a study published Oct. 30 in the journal JAMA Network Open.
