The full semantic toolbox referring to autism

Last week a publication (see below) was published as a commentary in the journal Autism Research. It states that researchers, parents, clinicians, educators and the overall community should not be limited in their use of language to describe the broad condition of autism. Some people experience impairments, deficits, and have limitations. Not only is it true, we should be talking about it. This podcast describes the motivation for the paper and the potential consequences of mandating the use terms that may not accurately reflect the diversity of experiences. While some papers have been published with the opposite sentiments, it’s important to understand both sides of this debate. We hope this paper leads to further conversation about this topic.

How that little amygdala makes a big difference in autism

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.

Environmental factors as both causes and interventions?

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. Read more in the studies below.

You asked, we listened: what is the link between ASD and ADHD?

This week’s ASF podcast topic comes from the listeners: what is the link between ASD and ADHD? Do parents diagnosed with ADHD have a greater chance of having a child with ASD? What are the similarities and differences? And what do families need to know? We interviewed Dr. Meghan Miller from the University of California Davis, who is one of the most prolific academics (and trusted psychologist to families) in this area.

Get some zzzzzz’s

Sleep is a huge problem in ASD. But is it just “sleep” or can we get more specific? What role do genetics have? And does being autistic make sleep problems worse? Answers come from an unlikely source: mice! Learn more about recent scientific evidence tying sleep problems to ASDs and neurodevelopmental disorders. These include: type of sleep problems autistic people face, why they exist, where they come from, and how mouse models can help solve them.

How you doin’?

We are now about 8 months into the pandemic and the effects of social distancing. How are families doing? What are scientists doing to understand the effects and ways to help families in the future? This podcast describes four international studies that addressed what families were experiencing and how they were coping. A list of references is below:

Psychiatric decompensation and autism: Two words you never want to hear together

A series of three scientific articles explore the link between the onset of psychiatric symptoms in adolescence in people with Phelan McDermid Syndrome, or PMS.  PMS is caused by a mutation in the SHANK3 gene, leading to a wide range of medical, behavioral and intellectual challenges, as well as autism spectrum disorder.  Scientists used a broad literature review as well as the PMS patient registry to better describe what was going on, and a group at Duke compiled a case series of girls affected that were responsive to treatment.  While so far this decompensation as a result of onset of psychiatric illness has only been documented in PMS, families across the spectrum should be aware so they can seek immediate help for their child if they see similar symptoms.

“ASADHD” – where does ASD and ADHD join together, and go their separate ways?

One the surface, symptoms of ADHD and ASD may seem very similar.  However, they come from very different places.  The genetic and behavioral makeup may be on the same spectrum across the two disorders, but they are actually farther apart than you might think.  Dr. Meghan Miller from UC Davis MIND Institute who studies both ADHD and ASD and people with ADHD and ASD explains what those differences and similarities are, how to make the right diagnosis, and what’s on the horizon for treatments for ADHD in people with ASD.
