Genetics does not equal eugenics

Sometimes when the autism community hears the words “genetics research”, it conjures up images of using genetics to eliminate people with autism. In fact, that’s not the goal of genetics research, nor is it even possible. Recently, several new studies were publish which illustrate how genetics can be used to help people understand their diagnosis, and receive more targeted supports. Special guest Jonathan Sebat from UCSD provides perspective on these findings and why genetics research is misunderstood.

Is anxiety related to autism, and where is it in the brain?

Anxiety is common in people with autism – but is is different than other types of anxiety or similar? Is it part of the autism phenotype? When does it start and what triggers it? Two new studies which use a longitudinal design and examine the links between autism features, anxiety symptoms and brain development are summarized this week. It shows that the amygdala is important, that some features of anxiety are core to ASD and some are separate, and it is related to autism features like insistence on sameness. This has implications for how anxiety is diagnosed and treated in those with ASD.

Autism means different things to different people

At this year’s International Society of Autism Research meeting in Austin, TX, there was a variety of themes explored. From early development and milestones, to intervention and supports, to different features like sensory issues, treatment, and how to solve the problem of heterogeneity. It comes down to this: Autism means different things to different people. This is just a small subset of everything that was presented at #INSAR2022 and I hope that if you want to see more, you advocate to have the presentations posted online or even have the program book made available publicly. In the meantime, enjoy the 30 minute summary.

New ways to solve old problems

This week’s podcast focuses on innovative methodologies to understand how to reach black families, understand why and when autistic people prefer not to look at faces and how interventions can improve conversation and social communication. They use culturally and racially matched mentors, old home video tapes (keep taking those!) and machine learning to look not just at novel methods but novel ways of studying a particular outcome.

Watershed moments in development

Autism diagnosis at 3 years of age isn’t something that happens suddenly. It evolves, there are deficits seen early on and markers that are evident prior to 3 years. Some of them are cascading events – with problems in one area like motor function, other behaviors like reaching, grasping, and learning about the environment and interactions with other people are stunted. Sometimes, these cascading moments lead to a loss of language. Early intervention can turn these early deficits around so that communication, learning and daily functioning are continually supported and instead of one trajectory, another can be reached. This podcast highlights studies that demonstrate that with data, and with theory. But it is never boiled down to one thing, despite early studies that screen time use is linked with an ASD diagnosis.

How important is the sensory system?

Most people with autism have some sort of sensory dysfunction: hypersensitivity or hyposensitivity or sensory avoiding behaviors to touch, smell, sound, light. But a new study looking at kids from the Study to Explore Early Development (SEED) suggest that it may be more important than you think. In fact, it was the only feature to unify those with autism compared to those with developmental delay. Are there treatments outside of environmental supports to help sensory issues? There could be: a drug that tried and failed to treat other features of autism called arbacolfen supports the idea that this drug target could be helpful in treating sensory issues.

Passing as Non-Autistic

You may know this as “masking” or “camouflaging” where autistic adults intentionally or unintentionally hide their autistic features to pass as non-autistic because they want to hide some of their challenges. This week, Drs. Erin Libsack and Matthew Lerner from Stony Brook University summarize a systematic review on this behavior. The original goal was to develop their own studies, but as it turns out, there are still so many unanswered questions to deal with that were unearthed from this systematic review.

September26.org

Instead of a podcast, this week is a message in honor of the 1 year anniversary of the death of advocate and mother Feda Amaliti. Stay safe. Out of this tragedy, a website has been built that contains information for families on how to prepare for an unexpected emergency and what to do when it happens. Please go to www.september26.org.

Also, we need your help in figuring out what the needs of families with disabilities are in terms of safety training and education. Please fill out this survey: https://www.surveymonkey.com/r/LivingSafelyWithDisabilities2

Who cares about eye gaze?

Early changes in eye gaze – or the time spent looking at another person’s face compared to the scene around them – is diminished in ASD. It starts to decline at about 12 months and is linked to later social communication behaviors. But many people wonder why this is an early developing behavior worth studying? Also, what happens in school age to kids that show poor eye gaze and infancy, and those who are on the “broader spectrum” but not a diagnosis in infancy – how do they fare at school age? Devon Gangi from UC Davis MIND Institute talks to us about both of these things and why baby siblings are so important

Don’t say “….all autistic adults”

While there are commonalities across autistic adults on many things, they differ. It might be time to stop saying “…..all autistic adults” when describing those on the spectrum. For example, for the most part, most autistic adults prefer email or text over other methods except when talking to friends and family. It was not universal, but the most preferred methods. This is important for scientists to want to gather the input from autistic adults – use email and online surveys NOT the telephone. But even these online surveys have problems. Large online research studies have the advantage of gathering large sets of data from geographically diverse people in a short period of time, but they may be biased if they don’t report who answered them. Recommendations for how to at least deal with diversity in scientific literature is included.
