The amygdala has been shown to be differently sized in autistic people – at first it is too big then it becomes smaller than typically developing people. But how early are these differences seen and does it relate to a diagnosis? The Infant Brain Imaging Study tackled this question in a recent study which compared those who were likely to develop autism at 6 months to those with Fragile X to see if there were differences and if it was specific to autism. Their findings will surprise you and have implications for targeted supports and interventions. Listen to the podcast here.
Podcast: How that little amygdala makes a big difference in autism
This week is a pharmacopeia of inflation. The #ASFpodcast talks debilitating gastrointestinal issues and new efforts to understand and treat them (including the CANDID meeting www.candidgi.com), a new method to understand adverse events in those that cannot report them on their own, and new news on Celexa, which is used to treat anxiety. Listen to the podcast here.

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 INSAR 2022 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 here.

This week, the #ASFpodcast explores different types of interventions for which the core autism features are not necessarily the target, but those that enhance quality of life and provide help for irritability and emotional dysregulation. They include cooking, music therapies and antipsychotic medications. While they may not be effective in core autism features, they may help in other ways. Listen to the podcast here.

This year’s first podcast dedicated to COVID issues explores both caregiver and clinician satisfaction with telehealth. New studies explore this satisfaction with assessment as well as psychiatric interventions. Also, as a follow up to the INSAR presentations on resiliency in mental health, a new study from Canada explains what may be at the core of this resiliency. Finally – why are some autistic people still not getting vaccinated? Listen to the podcast here.

In February, the CDC worked with the American Academy of Pediatrics to update the developmental milestones that parents should use when referencing how their child is developing. These milestones describe what should be accomplished by times as young as 2 months and as old as 5 months. These are helpful to all parents who wonder “shouldn’t my child be walking by now” and “how many words should they be saying”? Pediatricians ask parents about these and parents are expected to know them, so prepare yourselves now. What are milestones? Why change them? What are the changes?

Parents or caregivers of children with ASD sometimes have a lot of difficulty helping their child brush their teeth. Parents and caregivers of children not on the spectrum have difficulty helping their child brush their teeth. By working with families on an individual level, coaching, encouraging and breaking down each of the steps of tooth brushing into something manageable, a group of Medicaid-eligible parents helped their children learn these skills on some level by the end of the study. Incredibly, 93% of parents who are trying to do it all with less, stayed in the program and felt more confident about their abilities. This study also used a randomized clinical trial design which compared the training and coaching with just those who got some toothbrushes and toothpastes in the mail. In this week’s #ASFpodcast, you get to hear from the leaders and the therapists who helped these families, what they did, and what worked. Join me with Dr. Eric Butter, Kelly Birmingham and Dr. Rachel Fenning to hear more about this study. Listen to the podcast here.
This year’s Day of Learning was a huge success, with topics ranging from biological sex differences to mobile technologies all the way to the importance and documented value of leisure activities in people on the spectrum. the speakers included a discussion of the IACC, sex differences, the value of prevalence data, mobile technologies, leisure activities, and a recognition of two advocates who made or make a difference in families: Samantha Els and Suzanne Wright. Listen to this week’s podcast here for a quickie, but don’t let it prevent you from watching the longer videos, a link to which can be found below.
The answer is obviously “no”, however, animal models are necessary to help understand brain circuitry and improve interventions and supports for not just core symptoms but associated issues like anxiety, OCD, seizures and GI issues. Scientists view behaviors consistent with an ASD diagnosis differently, and this has created some problems in interpretation of animal model data. This week’s #ASFpodcast will break down a recent paper in Genes, Brain and Behavior which addresses inconsistencies in the literature and makes recommendations on how researchers should shift how they think about how they can replicate features of ASD in a model system.

| Environmental exposures, including toxic chemicals, can contribute to the causes of ASD. But how do other environmental factors, like behavioral supports, work in the brain to improve behaviors associated with ASD? For this, you need a broad interpretation of the term “environmental” and an animal model so you can see the mechanism involved. Studies show while environmental factors can contribute, they can also provide modifications in cellular and molecular function which support learning and improved developmental trajectory. Finally, on a different topic, are autistic adults more likely to be involved in a crime compared to other groups? No, they are not, but there are factors which affect the risk of being involved with the criminal justice system, at least in the UK.

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.

| Several studies have linked the immune system to autism, but how are they connected? Two new studies this week illustrate differences in immune function in those with a diagnosis compared to those without, and also find differences in the blood of of pregnant mothers who go on to have an autistic child. Women who go on to have autistic girls show higher levels and more inflammatory markers than mothers who go on to have boys, the finding of elevated IL1 is now a finding that has been replicated across countries. However, it’s too early to tell if this information can be used to help with a diagnosis and it’s probably not specific to autism. But the message is the same as it was before: getting sick during pregnancy is not great. Get vaccinated! Stay away from sick people and wash your hands. https://pubmed.ncbi.nlm.nih.gov/35110990/ https://pubmed.ncbi.nlm.nih.gov/34987169/ |
