On this week’s podcast, Dr. Elaine Clarke from @RutgersU discusses the role of adaptive behavior. This refers to the wide range of skills that a person with autism can exhibit. Can they hold a conversation? Dress themselves? Prepare a meal? These sets of skills are strongly influenced by cognitive ability. Dr. Clarke will talk about the link between cognitive ability and adaptive behaviors and while there may be differences in the abilities across the spectrum, it means clinicians and families need to aim for what works best for their individual child.

Last week in North Carolina, the Meeting on Language in Autism was held, with 3 days of amazing presentations and lots of productive discussions about how language and speech develops and how people with autism communicate. This podcast describes the origins of language development and how intervention during toddlerhood can promote lifelong language abilities. To learn more about the meeting go to www.mola.org and to see the Autism Navigator, go to www.autismnavigator.org.

There are dozens of good reasons why scientists need to study the brains of people with autism. One is to understand what happens in the brain as people with autism get older and see how the brain changes over time. Another is to identify mechanisms of autism to help all neuroscientists figure out how the brain works. A third is improve medicine by determining what helps what people at what age. Scientists @UCDavis, @Penn and @UCLA examined the individual brain cells of people with autism to address these three questions, revealing that the autistic brain shows some similarities to brains of people with Alzheimer’s Disease. In addition, inflammation seen in the brain may be caused by too much activity of cells talking to each other. Studying the brains of people with autism is essential to better understanding and is made possible by families who are committed to research. www.autismbrainnet.org.

We normally focus on the function of brain cells that send signals to eachother and communicate across small or long distances, which show differences in ASD. However, we rarely pay attention to the other cells in the brain. One type of cell, called the microglia, has been shown to not only help “pick up the garbage” of the brain, but also shape these connections that occur between brain cells. This week @DavidMenassa1 from @QueensCollegeOx, @UniofOxford, @unisouthampton published a paper in @Dev_Cell that looks at how microglia shape the brain during critical periods of development, and what this means for ASD. We are grateful he shares his expertise (and a beautiful accent) with us this week.

In February, the CDC worked with the American Academy of Pediatrics to update the developmental milestones that parents should use when referencing how their child is developing. These milestones describe what should be accomplished by times as young as 2 months and as old as 5 months. These are helpful to all parents who wonder “shouldn’t my child be walking by now” and “how many words should they be saying”? Pediatricians ask parents about these and parents are expected to know them, so prepare yourselves now. What are milestones? Why change them? What are the changes?

On this week’s podcast, we interview Dr. Giacomo Vivanti from the AJ Drexel Autism Institute who, together with Daniel Messinger from University of Miami, wrote an analysis of how research and intervention have changed since the DSMIII was written 40 years ago. They include theories of the causes of autism, the theories of the deficits and strengths of autism as it has changed over time, as well as intervention styles to meet the expanding understanding of autism. You can read the paper below, but Dr. Vivanti gives a great summary in a 30 minute interview!

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.

Not all people with autism spectrum disorder are the same, obviously. Are there things that can predict positive outcome? Are they different based on something like cognitive ability? And what determines cognitive ability and how early is it seen? Have other studies lumped all the autisms into one pile which has represented what people along the spectrum at different points actually need? This podcast tackles it all this week.

The words “induced pluripotent stem cell” refer to a group of cells that are gathered from a person with a disorder, like autism, then changed or “induced” from a skin cell into an embryonic “stem” cell, and can be then made into baby brain cells, or baby heart cells or baby bone cells. This makes them “pluripotent”. This tool has been used in neurodevelopment disorders to help illustrate when the wiring of the brain starts to go off course. Things start to happen very early after conception and one of the only ways to study these things is by using either embryonic cells or these induced embryonic “stem cells”. The latter is more cost effective and more precise. This technology has an incredibly high potential in understanding autism, but it may never be used as a treatment. Nevertheless, knowing how and when brain development deviates is essential for understanding people with ASD.

This week’s headlines were focused on the new prevalence numbers of 1:40.  They were not calculated using the same method as the 1:59 number, so should not be  compared.  In addition to looking at just prevalence, this survey identified a major problem for families, which is unmet mental health needs.  Those with autism have higher unmet mental health needs than those with  ADHD, anxiety or depression.  Again, there is something unique about an autism diagnosis which poses a challenge to accessing care.  In addition, a new summary paper outlined what needs to be done to better study  regression in autism.  The rate may be higher than you think if a new definition of regression is used.
