In 40 minutes, ASF summarizes the highlights in autism research from before diagnosis through adulthood. It includes new intervention studies, ways to better diagnose ASD, to understand symptoms, females, sexuality, employment, neurobiology, genetics, and gene x environment interactions. The major themes are the “H” word, or heterogeneity in symptoms across the spectrum, ways to make the broad spectrum smaller, and how big data approaches are helping make this happen. Thank you to families who participated in research and tireless autism researchers for lending their skills to answer the tough questions. And of course, thank you all for listening to these podcasts all year long. The transcript with all the references used will be posted on the ASF blog in the upcoming days.
