The disparity in diagnosis between Black kids and white kids is narrowing, but not by luck or coincidence. Based on previous research, clinicians are altering their professional training and their outreach to make sure more Black families are diagnosed and receive interventions. On today’s podcast, we highlight a recent study that focused on different ways to lower the age of diagnosis and improve access to early intervention in Black families. This intervention improved cognitive outcomes in Black kids.

Can we solve the pandemic problems around diagnosis and intervention?

This week’s #ASFpodcast highlights a few articles from the Journal of Autism and Developmental Disorders this week which examined the tolerability and efficacy of online diagnostic procedures and interventions, from the perspective of both parents and clinicians. They seem to work about the same, although there were some caveats. For many reasons, online and telehealth options are here to stay, and more needs to be done to improve their accuracy, acceptability, feasibility and effectiveness. These early studies are promising though, and lead the way to even more improvements to help make them a viable option for families in the future.

Is autism a yes/no diagnosis?

This week’s podcast highlights a paper from the IBIS (infant brain imaging study) that tracks infants from 6 months to 5 years of age to examine how ASD symptoms cluster together. These infants either have a diagnosis or they don’t, or they have something which doesn’t meet diagnostic threshold but is still impairing in some way. Ignoring the actual diagnosis, if the data is clustered together around how symptoms present, what happens? What does that mean for some of the longest standing research findings in ASD? For example, using this new approach which ignores and actual diagnosis, are more males are diagnosed than females? As it turns out, it equals out these ratios. What does this mean? Listen to this week’s podcast to hear directly from the first author, Catherine Burrows!

A deeper dive into racial disparities in ASD diagnosis

The racial and ethnic disparities in the diagnosis of ASD has always been unacceptable, but it’s been hard to figure out. This week, researchers published their findings from a close look at 500 African American families with ASD to understand what the barriers were to a timely diagnosis. The results are not surprising, but they are also alarming. Some of these families may benefit from telehealth in the future. Telehealth is not perfect, but it turning out to be helpful. For example, it may be beneficial in treating insomnia in people with ASD. Delivering cognitive behavioral therapy online resulted in improvements in sleep in adolescents with ASD. It isn’t a panacea, but it seems to be more helpful than people gave it credit for before the pandemic.

This one’s for the girls

In this week’s podcast, I semi-plagiarize from a recent summary of sex differences in ASD, written by Drs. Meng-Chuan Lai and Peter Szatmari from the University of Toronto.  They delve into why more males are diagnosed with females, and differences in the presentation of those features of ASD that differ between males and females.  These include camouflaging, differences in language style, differences based on behaviors determined by sex, and associated features like anxiety and internalizing behaviors.  Thank you to the authors for putting together the information in a way that makes sense.

CBT and ADDM – two acronyms in the autism news

Two studies missed last year (sorry) but are of importance to the autism community include a modified version of Cognitive Behavioral Therapy to treat anxiety, which was adapted and updated for people with ASD.  It also works better than traditional CBT, which is good news for  the 80% of people with ASD that also suffer from anxiety.  Also, in recognition of MLK day today, the CDC released information last year that shows that 1/4 of those that they counted in their prevalence numbers were missed by schools or other health care providers.  Unfortunately, those who were black or hispanic were more likely to be those that were missed but still met criteria.  This just shows that educators have to do better in helping those with ASD from all racial and ethnic backgrounds.

Autism: Difference or Dysfunction?

The question of whether or not autism is a difference or a true dysfunction in brain development has been debated for years.  A new study from Canada demonstrates that within an autism diagnosis, there is less of a difference in symptoms in the last 5 years than there was 30 years ago.  This raises a lot of questions about what autism researchers have been studying lately.  It also reinvigorates the discussion of whether the heterogeneity issue in autism has become such an issue that those with a true dysfunction are not getting the services they need, because of an interpretation that autism is just a difference.  The podcast includes thoughts of the community voiced on social media as well as opinions of the ASF scientific advisory board.

INSAR with a T, for “technology”

Lots of news outlets have great summaries of things that were presented at the International Society for Autism Research. However, one area was relatively missed:  technology.    This week’s podcast summarizes advances in technology for people with autism, how they are being used, what they could be used for and how they will improve services and help for those on the spectrum.  They range from ways to aid diagnosis, to better understanding of features and symptoms in different settings, to improved intervention.

Quality vs. Quantity in an autism diagnosis

In the fight to ensure everyone with autism is detected and diagnosed as early as possible, community providers are sometimes pushed to the limit in what they can do.  They have a huge caseload and there are long waitlists.  So how accurate are autism diagnoses given by these providers with little time and little resources for training?  As it turns out, they are just okay.  Approximately 23% of those diagnosed by community providers were not diagnosed using standardized and validated autism tools.  How can we weigh this potential over and mis-diagnosis with the potential for missing individuals with autism and depriving them of interventions and services?  That’s a topic for another discussion.  However, one question on the cause of autism was addressed and a theory debunked:  autism is not caused by caesarean section deliveries altering the microbiome, and then leading to ASD.  The microbiome may be involved, but not because of method of delivery and use of antibiotic medications.
