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.

Mysteries of the Microbiome

In the first of a two-part series on digestive health in ASD, Mia Kotikovski summarizes scientific information about what the complicated microbiome is, how it influences physical and psychiatric health, if it is altered in autism, and what causes it to be different in ASD.

More about the environmental influences in autism

New research points to a previously understudied but fascinating mechanism by which environmental factors may lead to autism: it’s called the “GABA/glutamate switch” which is a critical period in development when certain cells turn from turning on cell activity to turning them off. These environmental factors may delay this process leading to long term effects on the developing brain consistent with autism. While this data on the mechanism is brand new, the topic of the environment in autism was inspired by a recent effort at NIEHS which is developing an interactive database for people to access information about what environmental exposures have been studied and how in autism.

Research for the end of Autism Action Month

In honor of the last week of Autism Awareness/Acceptance Month, we review two new scientific findings that call for more awareness and action, and less acceptance of the status quo. First: sex differences in autism are not well understood, and as it turns out, the influences on a diagnosis are different. Males have a higher rate of heritability compared to females. Second, those with rare genetic disorders have very few options for treatment, but a new study promises hope for more personalized approaches. The researchers use Timothy Syndrome as an example of how cells can start to function properly through a targeted approach which focuses on a small part of a gene. This is potentially life saving for individuals with this disorder.

How to predict severe and dangerous behavior

On the first podcast of 2024, we describe a new paper in the Journal of the American Medical Association or JAMA which uses physiological measurements like heart rate and skin conductance to predict severe and dangerous behaviors, specifically aggression. If aggression can be predicted, it might be able to be prevented. It turns out aggression can be predicted up to 3 minutes before an episode occurs, in the future these measures can be used to possibly redirect aggression. In a separate study, the issue of stigma is addressed. There is an intense debate over “person first” vs. “identity first” language in autism, promoting recommendations of using one over the other because fear that person first language promotes stigma against autism. A new study shows that there is no added prejudice or fear using either person first or identity first language, but the stigma associated with schizophrenia is worse than it is for autism. What contributes to stigma? There is a wide range of experiences and perceptions of autism that need to be addressed. It’s not as simple as the language used.

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.

Nobody ever talks about catatonia

Nobody ever talks about catatonia in autism. This podcast explores the symptoms of catatonia, how to measure it, what parents should know about tracking the symptoms, what the treatments are, and what the causes are. Dr. Martine Lamy from Cincinnati Children’s Hospital explains her work looking at genetic causes in those with catatonia and neurodevelopmental disorders. It’s important to do genetic testing on all individuals who present with catatonia because this information led to better treatments in some people. Identifying a genetic cause of not just catatonia but also neurodevelopmental disorders like ASD gives families a community but also allows them to identify more targeted interventions.

Little Brains Answer Big Questions

This week we talk to Sergiu Pasca from Stanford University. He has revolutionized the field of understanding the field of brain development in neurodevelopmental disorders and just published a new study which examined the genetic influence of brain assembly. The way he does this is quite remarkable. His lab uses assembloids, which are many many many stem cells which form into a tiny brain. He explains what an interneuron is, why it is important for brain function, and how genetics can influence how these neurons work. This way the development of the brain from the first cell can be tracked and even manipulated to understand what happens in autism, and what therapies might be the most helpful to target these interneurons. Thank you Dr. Pasca.

Top reasons to study the autistic brain

There are dozens of good reasons why scientists need to study the brains of people with autism. One is to understand what happens in the brain as people with autism get older and see how the brain changes over time. Another is to identify mechanisms of autism to help all neuroscientists figure out how the brain works. A third is improve medicine by determining what helps what people at what age. Scientists @UCDavis, @Penn and @UCLA examined the individual brain cells of people with autism to address these three questions, revealing that the autistic brain shows some similarities to brains of people with Alzheimer’s Disease. In addition, inflammation seen in the brain may be caused by too much activity of cells talking to each other. Studying the brains of people with autism is essential to better understanding and is made possible by families who are committed to research. www.autismbrainnet.org.
