Here’s what you won’t hear about that new JAMA study on Twitter

A couple of weeks ago, a group in Australia published a study that investigated the efficacy of a “preemptive” intervention. That is, what happens if you provide support to parents to improve social communication, interaction and skills in infants before a diagnosis can be made? The results have a lot of meaningful implications of what interventions are possible at this age, how they can be delivered, and what it means to NOT receive an autism diagnosis but still show challenges. But the Twitter hive didn’t perceive it that way. This week I explain what the study did and didn’t do, and how it can help people across the spectrum.

Infant motor issues and later autism diagnosis

Everyone knows the way to study infants with autism is through thorough testing of younger siblings of those with a diagnosis, who have a 15x greater chance of have a diagnosis themselves.   Through these methods, new ways of identifying and predicting autism  later on have been developed.  On this week’s podcast:   two very influential and recent papers on the study of motor issues in 6 month olds who go on to be diagnosed with autism, and those  who don’t have an autism diagnosis but have signs and symptoms of ASD.  Are motor issues related to an ASD diagnosis or ASD symptoms?  And what about core symptoms of autism like language?   Can early motor behaviors be used to predict who goes on to receive an autism diagnosis or has language problems?  What should parents do?  How should this influence an early intervention plan?  Learn more this week!

Super siblings!

This podcast is dedicated to siblings of people with autism who are typically developing.  They play an important and beneficial role in development of socialization of those with ASD.  But sadly, they also have issues of their own, such as a high rate of issues like anxiety and depression.  Those siblings may be genetic carries of a specific mutation and not have an autism diagnosis, but have increased risk for schizophrenia and cognitive disability.  Finally, just because they are considered “typically developing” doesn’t mean they don’t have challenges with adaptive behavior.  However, they have a very special relationship with their brothers and sisters, and the world needs these strong advocates for the community.

Environment or genetics in autism symptomatology? How about both?

This week I am in Minneapolis at an incredibly important meeting of Medical Examiners to pitch them the importance of collecting brain tissue for Autism BrainNet.  While I was here I noticed a new study on the blogs that is important for families to hear about.  It focused on a known environmental exposure in established genetic groups.  The authors of the study, led by Dr. Sara Webb at University of Washington, showed that an environmental exposure can modify symptoms in genetically susceptible narrow subgroups.  This is the sort of research that will better describe how environmental exposures are affecting autism risk.   Thank you to Dr. Sara Webb for your perspectives and interpretation of the data!
