Factors That Influence Heterogeity and How

Understanding factors that make each person with autism different has been a challenge, affecting diagnosis, interventions and the way we think about autism in general. Researchers at Istituto Italiano di Tecnologia, Rovereto, Italy, used computers to see how language, intellectual ability, motor and adaptive functioning grouped individuals into different categories. It turns out there are two groups – one group that improves over time and outperforms the other group consistently even in early life. The other group continues to struggle. These factors are not autism-specific, but do influence the creation of these different groups that are different biologically as well as behaviorally. This week’s podcast is an interview with the researchers on what it means for the future of understanding what might help what person at what time in their life.

The publication is open access and includes the model so their findings can be replicated widely: https://molecularautism.biomedcentral.com/articles/10.1186/s13229-024-00613-5

Profound Autism: The first meaningful autism subgroup

Instead of grouping together people with autism based on traditional severity scores, what if groupings were done based on functional outcome? Would this help better understand the broad spectrum of autism and why some people with autism are so different than others? Researchers at the University of Minnesota led by Kyle Sterrett, together with UCLA and UNC utilized a study that followed children with autism in the early 1990’s into their adulthood, in the 2020’s. They created and asked these families a set of questions (included in the manuscript below) to help identify levels of functioning in people with autism. This was done to help them and their families get the right support at right time. They found that these questions could differentiate people with Profound Autism based on things like level of independence and safety concerns. Dr. Sterrett talks with us on this week’s podcast to explain what they did and why it is so important.

Those who are minimally verbal or non speaking represent about 25% of those with an autism diagnosis, yet there is really a lack of effective interventions for this group of autistic individuals. It used to be that everyone who was non-speaking was thought to have minimal ability to understand language, since understanding and speaking are so linked in development. However, group at Boston University studied the largest group of non-speaking autistic individuals so far and discovered that about 25% of them understand more language than they can speak, although this ability is still far lower than those who are neurotypical. The other 75% understand about as much as they can communicate verbally. This indicates that in some cases, the ability to understand words and their meaning exceeds the ability to communicate those ideas verbally. Surprise surprise, just like everything autism – there are differences across the spectrum. Thanks to Yanru Chen at Boston University for explaining the study to us.

How to predict severe and dangerous behavior

On the first podcast of 2024, we describe a new paper in the Journal of the American Medical Association or JAMA which uses physiological measurements like heart rate and skin conductance to predict severe and dangerous behaviors, specifically aggression. If aggression can be predicted, it might be able to be prevented. It turns out aggression can be predicted up to 3 minutes before an episode occurs, in the future these measures can be used to possibly redirect aggression. In a separate study, the issue of stigma is addressed. There is an intense debate over “person first” vs. “identity first” language in autism, promoting recommendations of using one over the other because fear that person first language promotes stigma against autism. A new study shows that there is no added prejudice or fear using either person first or identity first language, but the stigma associated with schizophrenia is worse than it is for autism. What contributes to stigma? There is a wide range of experiences and perceptions of autism that need to be addressed. It’s not as simple as the language used.

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.

She working to do this through scientific study! If you or a family member is non-speaking or cognitively disabled, and want to help with improving measures of Quality of Life, click here: https://redcap.link/pablid
