An update on why there are fewer autistic females compared to males

This week, special podcast correspondent #MiaKotikovski summarizes new research on the increasing prevalence of autism, with a focus on females. While the number of diagnosed females is increasing faster than the number for males, females assigned at birth still are less likely to receive a diagnosis than males. Additional evidence points to females having more genetic mutations and lower cognitive ability, so the questions remain: Are there females with autism who are just not getting diagnosed despite having all the autism features? Why not? Does autism in females “look” the same as autism in males? What sets them apart? These articles are all featured in the year-end highlight of research, so this is the time to get a deep explanation of the latest in sex differences in #autism.

The Trouble with Transitions

This podcast has not covered transition from adolescence to adulthood in the past, probably because there has not been a lot of research in this area. Luckily, recently there has been a surge of investigations and scientifically – supported interventions and recommendations for individuals who are transitioning to adulthood. This podcast reviews the latest in where the gaps are and identified some (of many) areas that need further research. Here are the references that will be helpful.

What’s the latest on minocycline for autism?

This week’s podcast re-explores a question about a potential therapy for autism – minocycline. Minocycline is an antibiotic used to treat a number of different infections and some anecdotal reports have linked it to an improvement of autism. This has led to some experimental trials on minocycline, with inconclusive results. This week, a multisite study showed NO effects of minocycline for autism features or outcomes, but that doesn’t mean it is NOT a great antibotic. If you need it, use it! Also, do autistic people spend too much time on their screens? Well, they seem to spend more time on devices and screens, but it might all be bad. Listen to the podcast for more information on this.

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.

Little things to help the autism community

We’ve heard a lot about social robots – do they help? One or two studies are not going to answer this, but a systematic review and meta analysis will! It turns out when you combined all the data, they do help in social abilities, but not other areas. This is how technology can help those with autism, especially technology which can be adapted to address the heterogeneity across the spectrum. And what about more subtle changes in the environment like light, sound, the built environment in classrooms and the home? Are there things that can be done that should be taken into account when these things are being built or modified? Again, a review article can help decipher all of the little studies that have been published over the year. Listen to specific recommendations for builders, architects, and even you as you make your home more autism friendly.

Violent criminal behavior, screen time, and inter pregnancy interval – not all related to each other but all relevant to ASD

Many media reports have linked autism to violent criminal behavior, but statistically, autistic people are more likely to be the victims but not the perpetrators of violence. So what ELSE is going on in those with ASD who have committed a violent crime? A study in The Netherlands delves into this by collecting information on violent criminals with an ASD diagnosis. Also, families are always concerned about the time their kids spend on their screens, and COVID caused even more screen time – think about all the time spent in online school. But is it harmful? Are there benefits? And does it depend on the type of screen time? Listen to this week’s podcast to find out.

The risk of dementia in older adults

There have been several small, or small-ish, studies looking at the link between dementia and autism or ID. However, recently, the largest medical record study of 500k people, 12k of which were autistic and 26k were autistic and had ID, examining early onset dementia was published. Those with ASD had a 1.9 increased risk for dementia and it was even higher for those with ASD + ID. Why? Is it psychological or biological or both? Researchers at the AJ Drexel Autism Institute investigate.

Which came first, ASD or sleep problems?

People with autism have lots of problems, and sleep is one of them. This week’s podcast explores when these problems begin, which brain areas are involved, and how autism contributes to, or suffers from, lack of sleep. Does sleep make ASD worse or are ASD symptoms causing a sleep problems? It’s not a one way street, and the neurons that go to the wrong places at the wrong times which cause ASD, may also be contributing to lack of good sleep. References below:

“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.

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.
