How to capture the real onset patterns of autism

ahalladay@autismsciencefoundation.org — Mon, 07 Sep 2026 17:34:31 +0000

Autism does not start at one, two or three years. It is a condition with trajectories, where some individuals show signs early, others later. It doesn’t just happen after some mysterious “medical event”, people are born with it. Scientists know this by tracking outcomes of those with a high likelihood of autism all the way from birth to school age.

We need more research on why features do not show up the same in each person, and how you can predict not just an autism diagnosis but other co-occurring conditions that are common in autism. Finally, science on how to best support each person with autism across their lifespan must continue, not stop. @UCL and @KCL are conducting just that type of research – that understands that features of autism change over time, emerge at different ages and also are accompanied by different biological features. This week we talk to Tony Charman, Tessel Bazelmans, Emily Jones and Mark Johnson who are pioneers in understanding how autism features emerge and change over time, but start in early infancy.

What is the evidence that autism is genetic?

ahalladay@autismsciencefoundation.org — Sat, 22 Aug 2026 23:01:49 +0000

This week we talk to Drs. Steve Scherer, Lisa Bradley and Graham Collingridge who recently published research that shows the gene PTCHD1-AS influences social functioning in humans and mice, without influencing intellectual deficits. This is the newest data that shows a single gene can control social communication and not some of the other comorbid features of ASD. They review the data around genetic influences in autism, why the knowledge of the role of genes in autism has exploded in the past decade, evidence that specific genes lead to an autism diagnosis, and more specifically, what this gene does in the brain and why it took so long to identify it.

Genetic Testing

Calculating a gene x environment interaction in autism

ahalladay@autismsciencefoundation.org — Tue, 11 Aug 2026 01:03:15 +0000

Traditionally, scientists have been able to calculate the role of genes in autism, or the environment in autism. However, understanding the role of genes together with the environment, or the effects of the environment with a genetic background, has been very difficult. This is especially true with polygenic genetic risk factors, which is not a single gene but a combination of multiple genetic influences. Different environmental factors might be good candidates for testing because some of them are more accurately measured than others.

This week, we talk to Drs. Nilanjan Chatterjee and Christine Ladd Acosta both from Johns Hopkins University, who have tested and validated a new method to calculate the risk of not just genetics, or the environment but the two working together. They describe some of the factors they studied and why, and how this model can be used for further research questions.

Mysteries of Motor Abilities in Autism

ahalladay@autismsciencefoundation.org — Mon, 27 Jul 2026 14:51:01 +0000

This week’s podcast features beloved UCLA child neurologist Dr. Rujuta Wilson who helps families with autism and other neurological conditions, both with and without a known genetic condition. We discuss the overlap of motor disability with autism spectrum disorder, what we know, what we need to know and what research families can participate in to help solve these questions. Dr. Wilson also explains some common terms in motor abilities or disabilities and how recreational activities can enhance evidence-based therapies to improve motor function, and of course give joy to those participating.

What can understanding autistic transgender individuals tell us about sex differences in ASD?

ahalladay@autismsciencefoundation.org — Sun, 28 Jun 2026 15:52:51 +0000

Happy Pride! In honor of June, this week’s podcast focuses on the specific needs of those who are transgender or sexually diverse and also autistic. What is the prevalence of autism in those who are transgender and what is the prevalence of being transgender in those who are autistic? New research has emerged which shows that mental and physical health problems are more prevalent in those with an autism diagnosis and transgender compared to those who are not autistic and transgender. What can we learn about sex differences in diagnoses of males and females through studying those who are also transgender? Also, Laura Graham Holmes who authored one of the studies comments on the importance of her research.

Autism and disorders of aging

ahalladay@autismsciencefoundation.org — Sun, 14 Jun 2026 21:02:17 +0000

We have talked already about the link between autism and dementia, however a lesser known association is the one between autism and another disorder of aging: Parkinson’s Disease. A recent presentation at INSAR revealed what is known about the relationship, why they are related, what causes the association and what people with autism can do to possibly mitigate the onset of dementia and Parkinson’s Disease. Thank you to Dr. Blair Braden and Samantha Harker and Manuela Velez Galindo from the Autism and Brain Aging Lab at Arizona State University (@autismbrainaginglab @asuresearch) for joining this podcast and explaining the findings so far and what they mean for individuals and families with autism.

Antidepressants do not cause autism

ahalladay@autismsciencefoundation.org — Mon, 01 Jun 2026 19:11:35 +0000

In all the recent hype on the “overprescribing” of psychiatric medications, there is a circulating rumor antidepressant use in the mother during pregnancy has could be linked to an autism diagnosis in the child. Thankfully, there is research on this topic, and the results are clear: antidepressant exposure during pregnancy does not cause autism in children. Where would this idea come from? Early studies did show a weak link, but the association arises because there is a genetic link between having a psychiatric disorder like anxiety and stress and autism. Don’t stop taking your meds unless you discuss it with your doctor. References below:

Lost in translation: SPARK NS helps scientists with a good idea turn it into therapies for families

ahalladay@autismsciencefoundation.org — Sun, 17 May 2026 23:51:23 +0000

SPARK – neuroscience, known to autism researchers as the other “SPARK”, is a project based out of Stanford University. This project does not collect genetics on hundreds of thousands of people, instead, they that provide funding, advice, support, mentorship, coaching and project management to scientists who have some evidence of a target in the brain relevant to autism. They help these scientists turn it into a potential drug or therapeutic that can help families. This is known as “translational research” and part of the “Valley of Death” where so many good drugs fail. This is a high-risk/high-reward endeavor. They are currently focused on therapeutics that target the functioning of the brain in autism and Parkinson’s Disease. Today’s guest is Dr. Opher Kornfeld, managing director of SPARK NS and neuroscientist. He explains how SPARK NS started, what they do, and how they have been successful helping scientists develop an idea into a potential product.

Somebody’s got to do it….it should someone from the autism community.

In November, there will be many Congressional seats open. Wouldn’t it be great if it was someone with firsthand knowledge of the experiences of autism families and understood what they were facing? In NJ, that is happening. Dr. Samuel Wang, autism researcher and autism sibling, is running for Congress. Today’s podcast interviews Dr. Wang, why …

Why is paramecetol safety so perplexing?

ahalladay@autismsciencefoundation.org — Sun, 19 Apr 2026 19:30:37 +0000

Another study on acetaminophen (known as paramecetol in Denmark) on probability of having a child with autism, this one with over 1.5 million pregnant women, 31k who were exposed to acetaminophen. The HHS Secretary is calling it “garbage in and garbage out” because it showed no link, but in fact, it is a strong study that examined multiple confounding variables and addressed questions that had been unanswered previously. This podcast is short and so is the message: Tylenol, also known as acetaminophen or paramecetol, taken during pregnancy, does not cause autism. Period.
