Reusing and recycling autism data from brain tissue

In a new study in animal models, researchers demonstrate how genetic variability in key risk genes leads to different brain development patterns.  Studying the brains of people with autism is challenging, since there are fewer resources to study.  However, scientists get creative and collaborative and re-analyze datasets previously published to look at different research questions.  That’s what happened this week in a collaboration between Brown University and UCLA, showing that as the activity of genes which controls the synapse goes down, so do genes affecting mitochondrial function.  Another brain tissue study showed that the stress of the endoplasmic reticulum, which is associated with the mitochondria, may be elevated.  Not all research data can be re-purposed again, which is why it is so important to study the brains of people with autism.  If you would like to learn more, go to www.takesbrains.org/signup

On the heels of Father’s Day, this week’s podcast summarizes the last year or so of research which focuses on the fathers.  This includes genetics, parental stress and quality of life, and broader autism phenotype features.   Of note, two new studies that look at antidepressant exposure in father and probability of having a child with autism – a variation on studying maternal exposures.   For anyone interested, here is a list of references used:

What the Tooth Fairy knows about autism

A new study uses baby teeth, which are formed in pregnancy and emerge at about 6 months to a year, to understand the dynamics of metals in people with autism.  Not just the levels, but the cycles of zinc and copper, which goes up and down normally with regular biological processes.  This could be the start to many more studies which use baby teeth to understand prenatal and early neonatal exposures in people with autism.  Also, the largest study published so far on food allergies confirmed a higher than normal presence of food, respiratory and skin allergies in people with autism.  Are allergies part of autism?  Probably not, but there seem to be a subgroup of people with immune issues that warrant specific treatments for those allergies.

Sobering statistics on suicide

Suicidal thoughts and suicidal attempts have been shown to be increased in people with ASD.  Rates are similar to those with bipolar depression and schizophrenia, but are higher even without psychosis.  This is shocking and an urgent health issue in the autism community.    This week’s podcast summarizes recent data, publications, presentations and concerns of thought leaders in autism about rates of suicide, what the risk factors are, and where research should be directed to prevent suicide.  If you or anyone you know is thinking about ending their life, please reach out to the National Suicide Prevention Hotline :  800 273 8255.
