Autism Science Foundation Weekly Science Report

During sleep, your brain is still active. It is turning all those things you learned during the day into long term memories through connections between the thalamus, hippocampus and frontal cortex. What happens in Profound Autism? How does the brain work during sleep and how will this knowledge lead to better sleep in people? Are there interventions already underway that are being tested that target sleep brainwaves? It can be hard to measure sleep, so in Part 2 of the Profound Autism Series, Dr. Dimitrios Mylonas from Harvard talks about his study to use portable home brain activity monitors that have been adapted for use in Profound Autism and an intervention based on this brain activity is being tested in other disorders. His study is now enrolling and is all remote, if you are interested in participating please email him at: [email protected]

In part 1 of a 3 part series on Profound Autism, ASF interviews Emily Ferguson, PhD from @Stanford shares what she learned by asking parents and caregivers of Profound Autism “what do you need?” The short answer was: “There is No Help“. The responses were overwhelmingly focused on inclusion in any program or service, since they are normally excluded from traditional programs. They also call for better multidisciplinary medical management. Needs were associated with a number of factors. Why talk to caregivers? Their perspectives help identify both research and service priorities in the future.

What is the probability of having a future child with autism if you already have one or more? Families want to know. It helps preparation, planning, will hopefully improve early screening and supports. The Baby Siblings Research Consortium analyzed a bigger group of siblings compared to their 2011 numbers and found the recurrence pretty stable – 1 in 5 siblings will have an autism diagnosis compared to 1 in 36 in the general population. However, this number depends on a lot of things: Sex of infant, sex of sibling with an existing ASD diagnosis, number of autistic children in the family, race and socioeconomic status. Listen this week to hear all the numbers.

In case you missed it, listen to Alison Singer with Gina Kavali on her podcast @LifeWiththeSpectrum. Alison talks about the importance of autism research and science in general, and how families can get involved.

On this week’s podcast, Mia Kotivkoski, founder of her own 5013c and recent graduate of Stony Brook University, reviews why understanding cultural and contextual factors influence not just an autism diagnosis but general health and outcomes of a broad group of people. They include immigrants, racial and ethnic differences, and socio-economic factors. What can be done? Listen to this week’s podcast to learn more.

This week, more on genetics as an influence to an autism diagnosis with a twist: can genetics lead to a specific treatment for core symptoms – across the board? How do you measure such broad symptoms? Our Rett Syndrome family friends and colleagues developed a novel outcome measure to capture what was most important to them, and the FDA approved it for use in a clinical trial. Years later, a new drug was approved that led to a reduction in behaviors associated with Rett Syndrome. Autism can take a lesson from this. In addition, can the genetics of autism be explained by parents with similar phenotypes? This is called assortative mating. The answer is complex.

Very rarely are scientists able to look at single genes within the brains of people across neuropsychiatric disorders and understand how the genes in each of these cells influence expression of proteins and interactions of different cells with each other. Recently, a collaboration called PsychENCODE released a series of papers that investigated what genes are expressed in what cells in autism in different situations, how cells that communicate interact with more support or glial cells, and what mechanisms are in place to identify ways in which the broad environment (chemicals, contextual factors, illness) may influence gene expression leading to disorders like autism, schizophrenia and bipolar disorder. This podcast summarizes these papers as they are related to autism – ore at least tries to.

In recognition of Father’s Day on the 16th, today’s podcast includes the latest research on fathers. Fathers may often be the “secondary caregiver” but should hardly be dismissed as inconsequential. Father’s sensitivity and insightfulness plays an important part in development, psychiatric diagnoses (including autism) change the the chance of having a child with autism, and more understanding is being done on the heritable factors associated with chemical exposures in the father.

General psychiatrists are trained deal with a range of psychiatric issues in a variety of areas, but very few have experience helping families of children and adults with autism. This is training that is desperately needed, as, like other professions, there are not enough psychiatrists to help families and waitlists are staggering. Dr. Arthur Westover at UT Southwestern discusses some potentially simple solutions, what he has tried and worked, and how families and advocacy groups can get more involved to ensure that doctors know about the unique and difficult psychiatric issues that autistics face. His ideas will not happen spontaneously, it’s going to take work to make psychiatrists more tuned into the needs of the autism community. He even wrote a paper (link below).
