What happens during sleep?

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: DMYLONAS@mgh.harvard.edu

Sleep is a huge problem in ASD. But is it just “sleep” or can we get more specific? What role do genetics have? And does being autistic make sleep problems worse? Answers come from an unlikely source: mice! Learn more about recent scientific evidence tying sleep problems to ASDs and neurodevelopmental disorders. These include: type of sleep problems autistic people face, why they exist, where they come from, and how mouse models can help solve them.

Which came first, ASD or sleep problems?

People with autism have lots of problems, and sleep is one of them. This week’s podcast explores when these problems begin, which brain areas are involved, and how autism contributes to, or suffers from, lack of sleep. Does sleep make ASD worse or are ASD symptoms causing a sleep problems? It’s not a one way street, and the neurons that go to the wrong places at the wrong times which cause ASD, may also be contributing to lack of good sleep. References below:

A deeper dive into racial disparities in ASD diagnosis

The racial and ethnic disparities in the diagnosis of ASD has always been unacceptable, but it’s been hard to figure out. This week, researchers published their findings from a close look at 500 African American families with ASD to understand what the barriers were to a timely diagnosis. The results are not surprising, but they are also alarming. Some of these families may benefit from telehealth in the future. Telehealth is not perfect, but it turning out to be helpful. For example, it may be beneficial in treating insomnia in people with ASD. Delivering cognitive behavioral therapy online resulted in improvements in sleep in adolescents with ASD. It isn’t a panacea, but it seems to be more helpful than people gave it credit for before the pandemic.

What works and does not work for wandering and sleep

This week a new study showed that kids with autism wander as early as toddlers, so parents keep a close eye on your kids no matter what their age.  Medications do not work, but behavioral interventions do seem to help.  This podcast gives some examples.   Also, another study shows the efficacy and safety of melatonin for helping kids with ASD fall asleep and stay asleep, even after 2 years.   Melatonin may not be the magic bullet we need for sleep problems, but it doesn’t seem to hurt either.

The waterbed around your brain (and its role in sleep)

This week we have a very special guest:  Dr. Mark Shen from University of North Carolina at Chapel Hill, who has been leading the field in understanding the role that the fluid around the brain in autism.  This week he expands his research to show that this increase in extra – axial (around the brain) fluid is not limited to those with a family history of autism, and is seen both before and after a diagnosis.  This has implications for early detection of ASD, but more interesting, it may help explain why some people with autism have so many sleep issues.

The ASF Day of Learning mini-recap

Did you miss the ASF Day of Learning in NYC but want to hear some teasers before they are available online?  Listen to this week’s podcast, and you’ll hear the 12 minute talks distilled to 2 minutes, leaving out a lot of details and eliminating the video part but giving you a quick recap of each.  Topics this year included:  1) What have we learned this last year?  2) Are Boys and Girls with Autism Different? 3) Does diet make a difference in autism?  4) Is medical marijuana a treatment option? 5) Why won’t my child sleep and 6) How can we improve adult outcomes in people with autism?  ASF also announced 8 new pre and post-doctoral fellowships on Wednesday, filling out an already amazingly active autism awareness month.   Stay tuned for the complete presentations to appear on the ASF homepage.

SLEEP: it’s what’s important for autism

Sleep disturbances affect up to 80% of people with autism, and as it turns out, these sleep problems translate to daytime problems like probability of hospitalization, severity of symptoms and even employment.  This week’s podcast focuses on three new studies that examine the relationship between sleep problems and function in people with autism across the spectrum, and provides new insights on how to study sleep.  Dr. Ashura Buckley from the NIH will be speaking about sleep in autism at the Day of Learning on April 11th – if you have’t registered yet, there is still time:  https://www.eventbrite.com/e/2018-autism-science-foundation-ted-style-autism-science-conference-registration-39878706284
