Resilience and heterogeneity in ASD

Everyone knows that every person with autism has their own unique strengths and challenges. Autism is heritable, and there are over 100 genes associated with autism. There are also an unknown number of environmental factors influencing outcome, so the heterogeneity is not necessarily surprising. But why would two people with the same genetic mutation have variable outcomes? Researchers led by the Institut Pasteur in France looked at the range of outcomes in people with a rare genetic mutation associated with autism, focusing on those without an autism diagnosis. This week’s podcast is an interview with the lead author of the paper, Thomas Rolland, PhD from France. The presence of the variants in those without ASD were associated with lowered cognitive ability, education level and employment status. The bottom line of these finds are that genes affect proteins which form the brain and control brain function. However, there are multiple factors that influence outcome. Some of them may be sex or gender, prenatal exposures. It’s not just one thing, there are many things influencing an autism diagnosis.

All who wander are not lost. But many are lost and need help.

In recognition of September 26th, this podcast explores one of the more dangerous issues in autism: wandering. But it’s really not wandering in the traditional sense. Wandering in autism mostly means running off, bolting, deliberately with intent and without permission. Obviously this leads to some very dangerous situations for people on the spectrum. How can it be mitigated or understood? Some behavioral therapies are helpful, but new technologies have allowed for more options to bring back loved ones that have run off unexpectedly. Finally, the community needs to be better aware of possible stressors or triggers that trigger a wandering episode and work together with families to prevent running off. This problem is not caused by one thing, and the community needs multiple solutions to keep kids and adults safe.

Support for Siblings during COVID

Everyone needed support during the pandemic, but families affected by autismneeded special support. This included siblings. Researchers at Massachusetts General Hospital tried out an intervention around stress and anxiety reduction in siblings in 2020. Not only was it liked, it worked. It didn’t completely eliminate stress and anxiety, nothing would, but it did help siblings manage a little better. Can it work outside the pandemic? There are certainly other situations where siblings could use a little more support.

Tik-Tok for autism information? Nope

In a highly discussed paper, researchers from Drexel University report their findings on a scientific and methodologically rigorous study on the accuracy of information posted on the social media platform Tik-Tok. They also discuss where the information comes from and how it is viewed. The accurate and inaccurate posts get “liked” equally, meaning they are taken just as seriously. There are billions of inaccurate posts being viewed, and misinformation spread. On this week’s podcast, all four authors of this paper summarize what they found and what families should know.

Suicide, self-harm and genetics in autism

This week’s podcast covers two new papers of interest to the autism community. First, another study showing increase in self harm and suicide in those with autism – no new news there – but a new discovery this week showed a vulnerability of females with a diagnosis. The study also explores the lower rate of suicide in those with IDD but higher rate of self harm in this same group. Second, the mystery of autism genetics is slowly unveiled. Why is rare variation so influential in an autism diagnosis? As it turns out those with rare variation also have common variation, piling on the genetic liability in this group. Common variation is also uniquely linked to language delay in autism, so is this a core feature? Links below are the scientific articles as well as resources to support those dealing with mental health problems in the autistic community.

Top reasons to study the autistic brain

Podcast: Play in new window | Download

Subscribe: RSS

There are dozens of good reasons why scientists need to study the brains of people with autism. One is to understand what happens in the brain as people with autism get older and see how the brain changes over time. Another is to identify mechanisms of autism to help all neuroscientists figure out how the brain works. A third is improve medicine by determining what helps what people at what age. Scientists @UCDavis, @Penn and @UCLA examined the individual brain cells of people with autism to address these three questions, revealing that the autistic brain shows some similarities to brains of people with Alzheimer’s Disease. In addition, inflammation seen in the brain may be caused by too much activity of cells talking to each other. Studying the brains of people with autism is essential to better understanding and is made possible by families who are committed to research. www.autismbrainnet.org.

“Emergent and Transactional” with Dr. Andrew Whitehouse

This week’s ASF podcast returns with a special guest: Dr. Andrew Whitehouse from the University of Western Australia talks about a new unifying theory of the spectrum of autism symptoms and features. It’s called “emergent and transactional”, and while the original author was Dr. Jonathan Green from the UK, Dr. Whitehouse wrote a clear explanation of what it means. He also provides his perspective on the broad spectrum of experiences, feelings and priorities in the autism community and how this new theory might bring together at least some of the views. We also discuss how courage and humility are needed by the entire community to reduce the vitriol.

This week’s podcast explores new evidence that exercise produces longer term improvements in coordination and motor skills. Parents can play a big role in how these skills are developed over time. Physical exercise also has different effects on the brain in typically developing people than those with a diagnosis.

The importance of a childhood diagnosis

Two recent papers suggest that a childhood diagnosis of ASD is important for adulthood quality of life and well being. But another one points out that it isn’t the only thing, or even the primary factor, involved in improved quality of life and well-being as autistic adults age. There are others, like comorbid mental health problems, demographic factors like gender and current age. These studies were conducted by autistic researchers and did an amazing thing – one tried to replicate the other. The media got the point of these findings wrong (shocker) so today’s #ASFpodcast explains what they mean.
