Autism Science Foundation Weekly Science Report Autism Science Foundation

The CDC released data from the Autism and Developmental Disabilities Monitoring Network (ADDM) on Thursday. In the past 2 years, the prevalence of autism has increased about 20%. Why? Are there more new cases or is diagnostic practices improving? For 20 years there has been fewer Black and Hispanic kids diagnosed. Is that still the case? Listen to this week’s #ASFpodcast to hear some early thoughts, the CDC will join us for an interview on April 20th:

TikTok is overtaking the internet and many are using this platform to learn about a variety of psychiatric illnesses and psychological problems. But how accurate are these videos in sharing medical information? Could they be causing things like tics? Do they influence individuals to self-diagnose and cause mis-diagnosis? There is a new phenomenon labeled “munchausen by internet”, and while some of the videos might be helpful in raising awareness, others are just spreading lies and causing psychiatric problems. In other words: be careful about TikTok. If a social media platform shares videos that tell you to eat laundry detergent, maybe you should not listen to everything they say.

Screening for autism is meant to cast a broad net to gather those who show enough features to be included for a full diagnostic evaluation. The most common of these tools is the MCHAT – the Modified Checklist for Autism in Toddlers. An author of the MCHAT, Diana Robins, and a colleague, Andrea Wieckowski and others gathered over 50 studies (English and other languages) in different types of samples (high likelihood and low likelihood) to determine how the MCHAT was doing in terms of finding infants with autism as well as excluding those without autism. It also touched on how well primary care doctors were doing in administering this tool. If you want to see the MCHAT for yourself or take it for your child, there is a FREE website, click here: https://mchatscreen.com

A new paper in Translational Psychiatry this week outlines the reasons why some conditions that occur with autism are actually co-morbid, and not co-occurring. The podcast will break down clues on why sometimes they are co-morbid, and present an argument on why they are important in understanding the vast heterogeneity of autism.

Just like no two people are the same, no two strains of mice are the same. Using dozens of different strains of mice with and without a genetic mutation associated with autism called CHD8, researchers at University of Southern California showed great variability in the effect of this mutation on behaviors associated with neurodevelopmental disorders. This can reflect the great differences across people with autism and even people with a rare genetic syndrome associated with autism. It isn’t just one gene, it’s the other hundreds of genes that can contribute to susceptibility or resilience to different features of NDDs. One thing this study did not do was overlay environmental factors, which will also significantly influence the variability seen across the different background genetics in these mice.

This week’s #ASFpodcast highlights a new study from Dr. Elizabeth Kaplan-Kahn, who is improving a measure of Quality of Life for autistic individuals who are minimally verbal or have cognitive disabilities. These individuals may have different outcomes as other autistics, but their responses are just as important. Dr. Kaplan-Kahn talks about what it means, how it is related to other outcomes collected, and what’s she’s doing to improve Quality of Life measures.
