How does autism prediction work?

This podcast provides updates on studies that help with prediction of an autism diagnosis – which is important for preparing for the future and for intervening early. First, a study that uses environmental factors to create an equation for the probability of a diagnosis following a combination of of non-genetic factors only which does a fairly good, but not perfect, job at predicting a diagnosis. Second, a study that looks at the accuracy of a machine that predicts autism from eye gaze as early as 9 months of age and with only a 2 minute test. This one wasn’t as accurate as the one that takes longer and tests older kids, but it’s a first step. No ONE thing does a perfect job at predicting a diagnosis – it’s going to be a combination of things, tested over time and multiple times that will be most helpful at predicting a diagnosis. Both studies are open access!

Scientists know in their gut how the GI symptoms are linked to autism

People with autism have higher levels of GI problems then people without a diagnosis, and the microbiome is associated with GI function, so is the microbiome linked to autism?  Some studies say yes, but this week studies in China look at non-caucasian people eating different diet.  Do the differences still hold?  Also, while GI  symptoms have been studied in relation to core autism features, they have not yet been linked to psychiatric issues like anxiety, ADHD, and aggression.  Until now.  This week’s podcast features three new studies looking GI issues and the causes of those issues, in kids with autism.
