brain – ASF Weekly Science Podcasts

This week we talk to Dr. Dan Geschwind from UCLA who was funded by the Autism Data Science Initiative to study thousands of environmental chemicals and medicines across various genetic backgrounds. A decade ago, this study would have taken a decade, but through new technology, robotics, and existing knowledge about genes and these chemicals, it is automated and can be done is 3 years. Dr. Geschwind will explain how he is using cells from people with autism to identify potential environmental factors that may contribute to a diagnosis of autism, or exacerbate or aleviate symptoms of autism and developmental disorders. This is incredibly cool – have a listen to what this ADSI project is doing and what it can tell scientists about what is important to focus on in autism.

Autism does not start at one, two or three years. It is a condition with trajectories, where some individuals show signs early, others later. It doesn’t just happen after some mysterious “medical event”, people are born with it. Scientists know this by tracking outcomes of those with a high likelihood of autism all the way from birth to school age.

We need more research on why features do not show up the same in each person, and how you can predict not just an autism diagnosis but other co-occurring conditions that are common in autism. Finally, science on how to best support each person with autism across their lifespan must continue, not stop. @UCL and @KCL are conducting just that type of research – that understands that features of autism change over time, emerge at different ages and also are accompanied by different biological features. This week we talk to Tony Charman, Tessel Bazelmans, Emily Jones and Mark Johnson who are pioneers in understanding how autism features emerge and change over time, but start in early infancy.

This week’s podcast features beloved UCLA child neurologist Dr. Rujuta Wilson who helps families with autism and other neurological conditions, both with and without a known genetic condition. We discuss the overlap of motor disability with autism spectrum disorder, what we know, what we need to know and what research families can participate in to help solve these questions. Dr. Wilson also explains some common terms in motor abilities or disabilities and how recreational activities can enhance evidence-based therapies to improve motor function, and of course give joy to those participating.

SPARK – neuroscience, known to autism researchers as the other “SPARK”, is a project based out of Stanford University. This project does not collect genetics on hundreds of thousands of people, instead, they that provide funding, advice, support, mentorship, coaching and project management to scientists who have some evidence of a target in the brain relevant to autism. They help these scientists turn it into a potential drug or therapeutic that can help families. This is known as “translational research” and part of the “Valley of Death” where so many good drugs fail. This is a high-risk/high-reward endeavor. They are currently focused on therapeutics that target the functioning of the brain in autism and Parkinson’s Disease. Today’s guest is Dr. Opher Kornfeld, managing director of SPARK NS and neuroscientist. He explains how SPARK NS started, what they do, and how they have been successful helping scientists develop an idea into a potential product.

The immune system is critically involved in autism. Of course, there are still a lot of questions to answer, particularly whether dysregulation of the immune system is the cause or a consequence of autism among others. But it is not studied enough. This week’s podcast includes new studies that examine the role of the immune system in autism, and outlines the different theories of how the immune system is involved in ASD.

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.

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.

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.

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: [email protected]

Catatonia is a syndrome which includes immobility, stupor, and sometimes regression in psychiatric wellness or even ability to feed or take care of ones self. This syndrome is seen in autism about 10% of the time but is is often overlooked or misdiagnosed. This may be because the symptoms are relatively rare or because catatonia is harder to detect in those with autism. This week, special guests Drs. Joshua Smith and Dr. Zachary Williams from Vanderbilt University discuss what happens when researchers following people who are suffering from catatonia and autism across time. What treatments work? How?

ASF has partnered with NCSA, Autism Speaks, Vanderbilt University, the Catatonia Foundation and other groups to bring you a 6 part series on catatonia given by experts and family members. It is aimed at increasing the visibility and research priority of catatonia. It is NOT this podcast – you have to register via zoom seperately here:
