Who cares about eye gaze?

Early changes in eye gaze – or the time spent looking at another person’s face compared to the scene around them – is diminished in ASD. It starts to decline at about 12 months and is linked to later social communication behaviors. But many people wonder why this is an early developing behavior worth studying? Also, what happens in school age to kids that show poor eye gaze and infancy, and those who are on the “broader spectrum” but not a diagnosis in infancy – how do they fare at school age? Devon Gangi from UC Davis MIND Institute talks to us about both of these things and why baby siblings are so important

Super, Superb and Sensational Siblings

Siblings of people on the spectrum, including autistic adults, are amazing. They support, advocate, fundraise, and now we know they actually have a direct influence on the outcome of their affected brother or sister. What’s that effect? When is it most obvious? Does gender or race matter? All of these questions will be answered by Nicole Rosen of UCLA on this week’s #ASFpodcast. And make sure to tune on on September 8th to or Sam’s Sibs Stick Together webinar. Info below.

Let’s Get Some Physical Activity

Everyone needs some physical activity, but people on the spectrum typically get less activity than those not diagnosed with ASD. Why? There are multiple reasons, but as it turns out it can’t all be blamed on the obvious culprit of increased screen time or video game use. Those can be reasons why teenagers get less activity, but not specifically those with ASD. Does physical activity help with ASD symptoms and features? Maybe a little. Different types of physical activity are discussed on this week’s ASF podcast.

Sex differences: It’s not about the diagnostic measurements.

A fresh take on an existing topic: why there are more boys diagnosed with ASD than girls. Even from a few months old, girls are different than boys, and they show subtle differences in toddlerhood. But at the time of diagnosis, they score the same on standardized instruments of ASD used to categorize someone as having ASD or not. This means it isn’t about the measures. It could be cultural factors, it could be a protective effect, but there needs to be a better understanding of these differences across the lifespan to help everyone with ASD, especially females.

The 2019 Year End Summary

What more appropriate podcast to end 2019 with than the summary of advances of scientific research of autism spectrum disorders?   The SAB of ASF and the CSO categorized the highlights in science into 8 categories which are outlined in this 30 minute podcast.  You can also read them on the ASF website here.  Thank you for listening to the ASF Weekly Science Podcast in 2019, and talk to you in 2020!

Mirror mirror on the wall, what is the fairest early predictor of adult language ability?

Scientists study motor skills in early development not just because it is one of the first features to emerge, but because it is predictive of later social communication development, and as it turns out, later expressive language development.   A new study combining data from 2 countries shows that early motor deficits predict language abilities all the way up to age 19, so focusing on early motor skills is imperative for early intervention.  Also this week – a review on why those tiny details in genetics of ASD can be so helpful for people across the spectrum and families.

The 2018 Year in Review: A spectrum within a spectrum

There were a number of exciting advances in scientific understanding autism in 2018.  These include things that we know to be true, and know to be not true.  Researchers made progress in identifying subgroups of ASD, defining biological markers, and developing  interventions. There were also research that demonstrates that while autism is a spectrum itself, it is also part of a bigger spectrum of neurodevelopmental disorders from anxiety to ADHD to OCD.  Therefore, the approaches to these other conditions may be applicable to ASD. In addition, there may be more similarities than differences in the biological features of these conditions.

This is just a sampling of the exciting research presented on this year’s Year in Review.  You can also read the full summary, complete with references, HERE.

The average age of diagnosis depends on where, when, and how you ask

While autism can be diagnosed reliably by 2 years of age, some people with autism don’t receive a formal diagnosis until much later.  Why not?  Racial and ethnic disparities as well as access to care issues are known factors.  This week, data from Denmark suggested that the diagnostic criteria has played a large role in prevalence in people with autism since 1980.  Many people who have autism may have been missed until they were older.  It suggests that older prevalence estimates were missing a proportion of autistic adolescents and adults.  Take away access and diagnostic barriers to a diagnosis, some kids followed from months of age in the baby siblings research consortium don’t receive a diagnosis at age 2, but do at age 5.  They always had autism, but their symptoms were sub-threshold for a formal diagnosis until age 5.

Through the years

Rarely can individuals with autism be studied more than once – but a new study tracks how cognitive and adaptive behavior changes over time.  What researchers in the British Autism of Infant Siblings, or BASIS found, was that family history of autism meant as much to cognitive and adaptive behavior than an actual autism diagnosis.  This calls for close monitoring of siblings of those with autism, regardless of whether or not they had a diagnosis.  Also, investigating psychiatric issues in children may underestimate their prevalence because many psychiatric issues do not emerge until the teenage years, so Kaiser Permanente looked at medical and health records of those with autism at 14-25 years to see what other issues they were facing, and the findings are both sobering yet maybe a little comforting.

What is the can do vs. the will do of autism?

Often overlooked in intervention studies, it is becoming increasingly clearer that adaptive behavior, the “will do” vs. the “can do” of functioning, should receive more focus.  In people with autism and high IQ, cognitive ability, the “can do” is higher than adaptive behavior, the “will do”.  Why?  The key in new research from the National Institutes of Health may be social abilities.  Another study this week from Children’s Hospital of Philadelphia in adult  with high IQ demonstrates that social motivation may be the key to improving social skills and socialization in people with ASD.
