The Importance of Model Systems

Animal models of autism, including cell based models, have received criticism because autism is a uniquely human condition so there is no value in studying it in a model like a mouse or a cell. On the other hand, model systems have been used for decades to develop therapies for a myraid of other conditions and disorders, and produced evidence-based treatments for not just autism but conditions from ADHD to schizophrenia. So why is there so much backlash about this line of research? The ASF podcast talks to Jill Silverman at UC Davis to get some perspective.

Where is autism stigma the worst in the world?

This week, part 1 in cultural stigma around autism with Mia Kotikovski provides an overview of stigma, where it can come from across cultures and provides some examples of stigma in different countries. Different areas of the world are in different places in terms of their perceptions of autism, their needs for autism families, and what they perceive as their greatest difficulties. The topic is so important we broke it down into two sections. Please listen to both, it will explain a lot about autism services and supports around the world.

Factors That Influence Heterogeity and How

Understanding factors that make each person with autism different has been a challenge, affecting diagnosis, interventions and the way we think about autism in general. Researchers at Istituto Italiano di Tecnologia, Rovereto, Italy, used computers to see how language, intellectual ability, motor and adaptive functioning grouped individuals into different categories. It turns out there are two groups – one group that improves over time and outperforms the other group consistently even in early life. The other group continues to struggle. These factors are not autism-specific, but do influence the creation of these different groups that are different biologically as well as behaviorally. This week’s podcast is an interview with the researchers on what it means for the future of understanding what might help what person at what time in their life.

The publication is open access and includes the model so their findings can be replicated widely: https://molecularautism.biomedcentral.com/articles/10.1186/s13229-024-00613-5

Post-Pandemic Problems

A few years after the start of the pandemic, and a couple of years into “recovery”, scientists are still disentangeling the effects of COVID-19 lockdowns and exposure. For example, is there an uptick in autism screen positives when pregnant mothers fell ill? Were there diagnostic disparities based on co-morbid conditions? Did autistic people feel better over time during the pandemic? This week’s #ASFpodcast explores these questions using new longitudinal data sets designed to better understand the long term impacts of the pandemic.
