Genetic pathways leading to autism

A landmark study that uses brain organoids from different people with different genes associated with autism showed that the different genes act as roads that go on different journeys to the same destination. This will be an enormously important discovery for identifying targets to treat different autism symptoms across different genetic causes of autism and understand the diversity of symptoms. Also, the new Interagency Autism Coordinating Committee was announced and there is not much breadth of perspectives.

What we learn from linking data

The NIH has launched the new Autism Data Science Initiative: https://dpcpsi.nih.gov/autism-data-science-initiative/funding-opportunities#section1, which brings questions about why linking different data sets is important. It can be done without including personal identifying information, and it should be done following ethical guidelines. If done correctly, using large datasets can answer questions relating to treatment, cause, better identification and personalized medicine for those on the spectrum. So what has linking data done for families? This week’s podcast summarizes longitudinal research that follows individuals across time, linking their information across different ages to look at factors that predict outcomes, environmental factors, and how to best support those on the spectrum.

News from the International Society for Autism Research Meeting, 2025

This year’s International Society of Autism Research Meeting was filled with great presentations about causes, diagnosis, interventions, mechanisms, supports, understanding sex differences and different populations of those with autism. But not everyone could fly to Seattle to attend. This week’s podcast provides a short summary of just some of the science presented. Michael Lombardo provided a keynote that included data from his research included on this podcast: https://blubrry.com/asfpodcast/137452290/factors-that-influence-heterogeity-and-how/

Do Transcranial Magnetic Stimulation and Direct Current Stimulation help people with autism? The latest science here.

Two therapies that are meant to alter brainwave activity, called Transcranial Magnetic Stimulation and Transcranial Direct Current Stimulation are receiving a lot of attention for potential efficacy in treating autism. They are non-invasive, which means treatment is provided on the scalp. While results vary, the overall evidence does not support these two interventions in helping to treat core autism features. However, as TMS is approved for depression and OCD, people should ask their doctors about these potential treatments if they suffer from these conditions. Learn more in the articles below:

Where is autism stigma the worst in the world?

This week, part 1 in cultural stigma around autism with Mia Kotikovski provides an overview of stigma, where it can come from across cultures and provides some examples of stigma in different countries. Different areas of the world are in different places in terms of their perceptions of autism, their needs for autism families, and what they perceive as their greatest difficulties. The topic is so important we broke it down into two sections. Please listen to both, it will explain a lot about autism services and supports around the world.

Dealing with an ER visit

This week, special correspondent Mia Kotikovski discusses challenges in getting emergency care for those with autism, what doctors and hospitals can do to ease the stressors associated with places like the ER. This is a huge issue for families as many “simple” ER visits for their autistic family members can cause such stress it provokes severe reactions, especially in those with sensory issues, intellectual disability or those who cannot express their pain.

Are new ICD-11 criteria for an autism diagnosis too vague?

In the last version of the Diagnostic and Statistical Manual, the different subtypes of autism were folded into one label: autism spectrum disorder. A similar revision is being made around the International Classification of Diseases, the system the WHO uses across the world to describe autism and provide appropriate reimbursements for services and supports. In this version, the ICD-11, a combination of 300 different presentations of autism are described. A diagnosis can be made if 1 feature of social-communication and 1 feature of repetitive behaviors are documented, with an onset of any time in life. This is causing a lot of confusion in the community, because since the presentations are not specific to autism, it is difficult to provide an accurate diagnosis using the ICD-11. This week we talk to German psychiatrist Inge Kamp-Becker, MD, who outlines what the changes are, and how misdiagnosis can be made and what those consequences might be. Her summary is linked below.

In support of AFAB

A recent publication in the Lancet was dedicated to clinical recommendations to support autistic females at birth. Because more males than females are diagnosed with autism, their needs are often misunderstood, misinterpreted, or just ignored. Researchers, clinicians, scientists, parents and self-advocates from around the world joined together to identify those needs and propose solutions that can be implemented in everyday care.

What doesn’t kill you makes you stronger

This week’s podcast explores new evidence that exercise produces longer term improvements in coordination and motor skills. Parents can play a big role in how these skills are developed over time. Physical exercise also has different effects on the brain in typically developing people than those with a diagnosis.

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.
