This one’s for the girls

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.

Autism and diseases of the aging brain

As the autistic brain ages, is it more vulnerable to other brain disorders? Recent scientific discoveries in Parkinson’s Disease and Alzheimer’s Disease show that there may be an underlying mechanism between these diseases and autism. However diagnosing someone with autism with an additional brain disorder, especially dementia, can be difficult. This week’s podcast covers the increased risk of Parkinson’s Disease in autism, as well as provides advice from a group of experts on how to diagnose an autistic person with dementia, since there may be overlap in features.

What labels should be used to describe autism?

This week’s podcast includes summaries from two new scientific studies (with comments from one of the studies’ authors @SimonsFoundation and @princetonPPH) about that tackle grouping and labeling the differences across the spectrum into meaningful subtypes. Both provide scientific evidence, including behavioral and biological data, that support the use of different labels. This is more evidence that lumping everyone into one unitary “autism” diagnosis is not meaningful or biologically accurate, and that using computer-driven approaches, different behavioral subtypes map onto behavioral features. This supports approaches that more clearly describe different types of autism for better supports.

This week’s ASF weekly science podcast features Dr. David Amaral, who directs the Autism BrainNet. The Autism BrainNet is a program that organizes the collection of post-mortem brain tissue and then distributes it to autism researchers worldwide to better understand the brains of people with autism. He discusses major scientific discoveries about the mechanisms of autism in the brain that were only possible by using this resource, and the brave generosity of families that make the program happen. Anyone can register to learn more about new scientific research and the program itself, it’s important that everyone at least know the program exists for future planning.

This week’s podcast includes Storyform Science founders H. Adam Steinberg and Holly Kerby, both scientists who now help other scientists use storytelling to convey the importance of their findings to a broad community. Anyone can do it, and it is so important to help communicate to the public, convince policymakers to listen and granters to fund research. They offer an online course starting in July to help students do this, you can learn more here: https://storyformscience.com.

The podcast includes visuals, so it is also posted on youtube here: https://youtu.be/hTFcpeVx4gI

Genetic therapies in store for neurodevelopmental disorders

Gene therapies have been in the news lately. They are being used to help individuals who have a genetic variant linked to a disorder or disease, including but not limited to: spinal muscular atrophy, carbamoyl phosphate synthetase 1 (CPS1) deficiency, diabetes and some types of cancers. What is the promise in rare genetic forms of neurodevelopmental disorders and autism? This week, scientists from Jaguar Gene Therapy discuss their ongoing studies in Phelan-McDermid Syndrome and how gene therapies hold promise for treating neurological impairments caused by a known genetic variant. The interview provides basic information of what a gene therapy is, how it works, how it is used and what is monitored during these treatments.

What we learn from linking data

The NIH has launched the new Autism Data Science Initiative: https://dpcpsi.nih.gov/autism-data-science-initiative/funding-opportunities#section1, which brings questions about why linking different data sets is important. It can be done without including personal identifying information, and it should be done following ethical guidelines. If done correctly, using large datasets can answer questions relating to treatment, cause, better identification and personalized medicine for those on the spectrum. So what has linking data done for families? This week’s podcast summarizes longitudinal research that follows individuals across time, linking their information across different ages to look at factors that predict outcomes, environmental factors, and how to best support those on the spectrum.

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/

With the International Society for Autism Research underway and a new wave of misunderstanding about scientific evidence in autism, it’s time to think about what is science, how is it conducted, and why does it take so long? Who benefits from science and how? This is just the start, but gives a quick overview of why science matters to families affected by autism.

Microglia as a target for new interventions

Podcast: Play in new window | Download

Subscribe: RSS

There is a cell in the brain called the microglia which has been traditionally overlooked as a target for therapies. New research supported by ASF and @FraxAresearch suggests that altering the function of microglia in the brain may help support the development of healthy and functional connections in the brain that may be impaired in autism, making the microglia a prime candidate for research. Drs. Marine Krzisch from @UniversityofLeeds and Dr. Mike Tranfaglia at @FraxAResearch describe the approach and how it can be developed to create specific therapies, that when combined with behavioral interventions, can drastically alter someone’s abilities. Dr. Krzisch is also interviewing families about how the findings will be explained when they are ready, what is important to them and what should research emphasize in the future. Participants will be compensated, just email her: M.Krzisch@leeds.ac.uk
