This week’s podcast is dedicated to the “T” in LGBTQ –  trans.  Several studies over the past few years have linked higher rates of gender variance in people with autism and higher rates of autism traits in those who are trans.  Why?  Are they biologically or psychologically linked or both?  This is important for understanding, not treatment or intervention.  This week’s podcast celebrates trans people who are also autistic.

Are animal models for ASD a monkey wrench or useful tool?

A new animal model of autism appeared this week:  the monkey.  This adds to the ever growing list of different model systems from autism, from fruit flies to mice and rats now up to monkeys.  Are these animal models useful and for what, and why isn’t there just ONE model of autism rather than the dozen that exist?  This week’s podcast discusses research from scientists at the UC Davis MIND Institute and what they are doing to improve these models of ASD.

Guys, we all need exercise

People with autism are less likely to be physically active and more likely to be sedentary.    A number of studies have looked into different physical activities, both group based and individually, on improvements in health as well as core features of autism, and most have had positive results.  New animal model research demonstrates a benefit of exercise using the maternal immune activation model of ASD, pruning back the excess of connections and cell fibers.  As people with autism also have too many connections in the brain, this may have a direct therapeutic benefit.  But besides all the scientific conjecture, we all need more exercise, physical activity interventions seem to only help, not hurt, people across the spectrum, and should be used to complement, not replace existing therapies.

Yeah, another study about autistic poop

This week’s podcast includes a summary of the new study, this time in an animal model, looking at microbiome transplantation.  Because this was more of an experimental model, the researchers could be more rigorous in their design and look at things like behavior, brain activity, and specific biological pathways.  While a mouse does not have autism, transplantation of the autism microbiome resulted in autistic-like behaviors.   Second, a hopeful message of the value of participating in research on outcomes – those infants that were tracked prospectively showed improved outcomes later on, suggesting that all of the extra attention they get leads to a reduction in symptoms and an improvement in adaptive behavior.  Even if you do not have a family history of autism – participate in research.  It’s good for your child, and it’s good for other people’s children.
