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:

We missed one for the 2024 year end summary: Proof of the importance of genetic testing in autism

It happens every year – this one belonged in the 2024 year end highlights but was published late in the year. Researchers at UCSD, UCLA and CHLA followed families with autism whose genetic test revealed a rare variant. Did it make a difference in care? Understanding? Referrals? If you are in need of a genetic test, here are some things to know: https://www.alliancegenda.org/genetic-testing

The 2024 Autism Science Year in Review

New Technologies, New Data, New Solutions

This year’s progress in autism research includes promising findings, clarifications, explanations, and the uncovering of new avenues of inquiry. The focus is now on personalized medicine: finding the right treatment for the right person at the right time through targeted interventions. Advances in technology and genetic testing are opening new avenues for therapeutics, rapid drug testing, and improved differentiation of subgroups of autism.

Synaptic Density and Autism, explained

….or at a podcast with at least an attempt at an explanation of what synaptic density is and how it is affected in brains of people with autism. This week we review three convergent lines of evidence – whole brain, brain cell then genes within those brain cells – that show that the autistic brain has a decrease in cell-to-cell communication in multiple brain regions, leading to social communication impairments.

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.
