This week, Drs. Casey Burrows from @UMN and Shuting Zheng from @UTexas discuss a new paper looking at sex differences in autism features from 20-40 months of age. A new analysis done with data from the Baby Siblings Research Consortium concludes that, early in life, girls with autism show differences in some autism features (like joint attention) compared to boys. There are many reasons for this, including that boys and girls are just different, period. However, it adds to mounting data which may help explain why more males are diagnosed compared to females. More research needs to examine how girls and females present, what symptoms are harder to observe in females andy why, and most importantly, sheds insight how girls and females with autism need to be specifically supported.

This year’s International Society of Autism Research Meeting was filled with great presentations about causes, diagnosis, interventions, mechanisms, supports, understanding sex differences and different populations of those with autism. But not everyone could fly to Seattle to attend. This week’s podcast provides a short summary of just some of the science presented. Michael Lombardo provided a keynote that included data from his research included on this podcast: https://blubrry.com/asfpodcast/137452290/factors-that-influence-heterogeity-and-how/

Contextual factors, or external factors, are environmental influences and can impact not just a diagnosis but the life course of a person with autism and their families. A recent commentary by autism researchers around the world highlights the importance of these factors and provides resources on how they can be collected in a rigorous, but accessible, way. Dr. Marsha Mailick, lead author of the commentary, discusses the definition of contextual factors, why they are important, and how they can influence development.
