Podcast: 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.

On this week’s ASF podcast: 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.

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.

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.

Compared to other types of research, there are so few studies that look at three time points in the same person with autism over their lifetime to better understand groups and predict outcomes. What is missing? What do families need? What’s there and what could be done differently to get at the answers that will help families? On this week’s podcast, we talk to @StevenGentles from McMaster University who led a review of this research and what it will add to the science.

Digital therapeutics may very helpful in helping families and individuals on the spectrum. What are they? How can they be used? This week’s #ASFpodcast talks to Lani Hessen from the Digital Therapeutics Alliance who is holding a summit this week in Washington DC. There is technology that is already used to help those on the spectrum, and those that can be easily adapted or implemented in those with a diagnosis or their families. We want to hear about YOUR experience with digital technologies. Tell us more in the comments.

With just a few weeks to go until June, this week’s podcast is a short summary of the prevalence of transsexuality in the autism community and how many people are autistic in the trans community. More importantly, there are guidelines about the identification and care for those who have these co-occurring conditions. The references mentioned are below:

Last week in Stockholm, Sweden, 2200 researchers and scientists working to understand and help those on the spectrum, met to share their most recent findings and exchange ideas. What were the main takeaways as ASF saw them? In our latest podcast episode, we cover why some autistic people don’t want genetics to be studied, how to better engage families with IDD and who are non-speaking, females, adults, international studies and yes, diversity. The program book was released a day before the meeting and can be found here: https://cdn.ymaws.com/www.autism-insar.org/resource/resmgr/docs/annualmeeting/insar2023_program_book.pdf

Individuals diagnosed with autism spectrum disorder (ASD) present with a highly diverse set of challenges, disabilities, impairments and strengths. Recently, it has been suggested that researchers and practitioners avoid using certain words to describe the difficulties and impairments experienced by individuals with ASD to reduce stigma. The proposed limitations on terminology were developed by only a subset of the autism community, and the recommendations are already causing negative consequences that may be harmful to future scientific and clinical endeavors and, ultimately, to people with ASD. No one should have the power to censor language to exclude the observable realities of autism. Scientists and clinicians must be able to use any scientifically accurate terms necessary to describe the wide range of autistic people they study and support, without fear of censure or retribution.

Keywords: Vocabulary; autism spectrum disorder; bias; language.

Eye tracking has long been used to characterize differences in social attention between autistic and non-autistic children, but recent work has shown that these patterns may vary widely according to the biological sex of the participants and the social complexity and gender-typicality of the eye tracking stimuli (e.g., barbies vs. transformers). To better understand effects of sex, social complexity, and object gender-typicality on social and non-social gaze behavior in autism, we compared the visual attention patterns of 67 autistic (ASD) and non-autistic (NA) males (M) and females (F) (ASD M = 21; ASD F = 18; NA M = 14; NA F = 14) across four eye tracking paradigms varying in social complexity and object gender-typicality. We found consistency across paradigms in terms of overall attention and attention to social stimuli, but attention to objects varied when paradigms considered gender in their stimulus design. Children attended more to gendered objects, particularly when the gender-typicality of the object matched their assigned sex. These results demonstrate that visual social attention in autism is affected by interactions between a child’s biological sex, social scene complexity, and object gender-typicality and have broad implications for the design and interpretation of eye tracking studies.

Keywords: attention; eye movement; gender/female ASD; sex differences.

What do anxiety, prevalence, ketamine, other neurodevelopmental disorders, siblings, genetics, brain imaging and the autistic researcher committee at INSAR all have in common? They were all topics at the last Day of Learning. You can hear a 20 minute summary of the talks on this week’s ASFpodcast.
