neurobiology – ASF Weekly Science Podcasts

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 … Continue reading "Autism and disorders of a...

The word “mitochondrial deficits” gets thrown around a lot as a cause of autism, but what does this really mean? This week we interview Dr. Carisa Sirois from the University of Wisconsin, who recently published a review of how the mitochondria are involved in neurodevelopmental disorders. The ways mitochondria are involved in ASD are not … Continue reading "The Mitochondria in a...

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 … Continue reading "Genetic pathw...

In an effort to better understand the causes of autism in those with a known genetic variant associated with ASD or other developmental disorders, in 2010, the Simons Foundation launched Simons VIP, now known as  Simons Searchlight – an online international research program studying nearly 200 rare genetic neurodevelopmental disorders and working with over 60 patient … Continue reading...

As the autistic brain ages, is it more vulnerable to other brain disorders? Recent scientific discoveries in Parkinson’s Disease and Alzheimer’s Disease show that there may be an underlying mechanism between these diseases and autism. However diagnosing someone with autism with an additional brain disorder, especially dementia, can be difficult. This week’s podcast covers the &#8...

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 … Continue...

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 … Continue reading "We missed one for the 2024 year end summary: Proof of the...

….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 … Continue reading "Synaptic Density and Autism, explained"

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 … Continue re...

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 … Continue reading "Research for the end of Autism Action Month"
