ADHD and ASD diagnosis both on the rise. Coincidence or commonalities?

Like ASD, the prevalence of ADHD has increased significantly in the past 2 decades. A critical analysis examines the factors, and many of them can be applicable to the increase in the rise of autism diagnoses: increased diagnosis in adults, looser diagnostic criteria, and untrained professionals making the diagnoses. While they are not of course the same, listen to some of their arguments and read their comments (link below) to see if you agree with my assessment.

The molecular signature of the autism brain

Is there a specific “signature’ that make the autism brain unique? Can there be a common set of findings that certain gene expression goes up and another go down and where? And is it linked to behavior? This week, Dr. Michael Gandal at University of Pennsylvania (formerly UCLA) explains his recent findings that looks at the largest number of brain tissue samples so far from multiple brain regions to show a common up regulation of immune genes in the brain and a common down regulation of genes which control synapse formation and neuronal communication. It is most pronounced in areas involved in sensory processing of the brain. You can listen to the podcast today and read the whole paper here:

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.

Bilingualism: is it best?

This week’s podcast explores the question about whether or not it is beneficial or just confusing to teach your child with autism multiple languages, or suppress the use of more than one language at home. Turns out, being bilingual helps with executive functioning (or those with preserved executive functioning can be bilingual), language, and provides benefits in verbal IQ depending on SES. In other words, it’s not harmful, it can be helpful, and those who choose to speak two languages at home should continue to do so if they feel that it is enhancing their child’s learning.

Genetic confounding plus organoids

You heard it in the news this week, and we discuss it on this week’s ASF podcast. Can you make little brains in a dish then make them better by providing them a real structured live neural environment? Can these organoids integrate with a live brain and be functional in vivo? The answers are: yes! Learn more from a new study published this week. Also, what the h**l is genetic confounding and how can it address many of the controversies of genetic vs. the environment? Sometimes genes that predispose to a disorder also predispose to environmental factors leading to that disorder. There is always room for both. Here are the links I promised:

The meaningful impact of clinical trials

Podcast: Play in new window | Download

Clinical trials in autism are so incredibly important to families and adults, but sometimes hard to understand. Why? How can it help me or my family? What do I need to do? What do all of these terms mean? For researchers: it’s hard to get families to participate in my study. What can I do to improve the appeal? Caroline Averius and Zachary Williams explain in this podcast about a newly launched two new guidebooks designed to help explain clinical trials, why they are important and what needs to be shared with the community to ensure transparency.

The Meaning of Microglia

Podcast: Play in new window | Download

Subscribe: RSS

We normally focus on the function of brain cells that send signals to eachother and communicate across small or long distances, which show differences in ASD. However, we rarely pay attention to the other cells in the brain. One type of cell, called the microglia, has been shown to not only help “pick up the garbage” of the brain, but also shape these connections that occur between brain cells. This week @DavidMenassa1 from @QueensCollegeOx, @UniofOxford, @unisouthampton published a paper in @Dev_Cell that looks at how microglia shape the brain during critical periods of development, and what this means for ASD. We are grateful he shares his expertise (and a beautiful accent) with us this week.

Psychedelics and Symptoms

More and more, psychiatrists are looking to psychedelic medication to help individuals who are resistant to other types of therapies. These include seizures, PTSD and depression. But can they help individuals with autism or ease autism-related problems or improve cognition? Two new studies on cannabis and one on ketamine are summarized in this week’s ASFpodcast. Promising, interesting, but not definitive. It’s a short podcast this week.

Genetics does not equal eugenics

Sometimes when the autism community hears the words “genetics research”, it conjures up images of using genetics to eliminate people with autism. In fact, that’s not the goal of genetics research, nor is it even possible. Recently, several new studies were publish which illustrate how genetics can be used to help people understand their diagnosis, and receive more targeted supports. Special guest Jonathan Sebat from UCSD provides perspective on these findings and why genetics research is misunderstood.
