From Early Detection to Early Intervention

This month, two new important research findings were published from scientists that study the very earliest signs and symptoms of autism.  First, Dr. Suzanne Macari at Yale showed that a type of temperament in toddlers was associated with autism at about 3 years of age.  This may be used in the future to develop specialized interventions very very early on.  Meanwhile, Dr. Jessica Brian’s group in Canada used the very early signs of autism – social orienting – to develop a new intervention called the Social ABC’s which they piloted last year.  Last week, a randomized clinical trial of this intervention showed improvements in social smiling, reactions to parents, and social orienting, suggesting it is a feasible and valid intervention option.  There is now a list of these interventions that have been rigorously tested.  This demonstrates that the early detection of features of autism, like temperament, can be turned into interventions to improve the outcome of toddlers with ASD.

What is the focus this week? The unsung heroes of grandparents and clinicians

Scientists have studied males compared to females with autism, but rarely has there been studies about what clinicians see as differences in these two groups.  Given that they provide insight on diagnosis, needs and access to services, it is kind of important to talk to them, and a study out this week in the journal Autism did just that.  You can find the full text here:

Also, scientists are starting to understand the role of exposures in parents and how they affect diagnosis of autism in their children, but this week a new wrench was thrown into the wheel:  researchers in the UK found that grandparental exposures play a role in autism diagnosis too.  Luckily, this too is open access and you can read it for yourself.  It was covered in the media and we have perspective from a parent included.

I discuss this second project with Jill Escher, founder of the Escher Fund for Autism and co-funder of the study.

Autism symptoms in girls with anorexia

This week summarizes some new studies looking at autism traits and autism diagnosis in girls with anorexia nervosa.  While the two disorders may seem different on the outset, they do share some behavioral features.  Unfortunately, most studies look at autism in those with anorexia, not the other way around.  However, what is known is that there is not only higher levels of ASD traits in girls with anorexia, about 10% of girls with anorexia also have an autism diagnosis.  This number can only be trusted if you look at both standardized observation instruments AND parental report.  Studies determining the rates of eating disorders in autism are desperately needed for better treatment of symptoms.

As always, good news and bad news in autism this week.  First the good news:  an intervention given between 9-14 months of age in children with a high probability of having an autism diagnosis improved autism symptoms at 3 years of age.  Now the bad:  mothers who experience severe childhood abuse are more likely to have a child with an autism diagnosis.  Why?  A new study explains it might have a lot to do with autism traits in the parents.  We would love to hear your thoughts on the results, please provide them in the comment section.

Oops the media did it again…

Last week CNN.com reported on a study that showed slight improvement of autism symptoms in children that received a single infusion of their own umbilical cord blood.  While the study was interesting, the authors were the first to acknowledge the limitations, however, this did not stop the media from misrepresenting the results.  Details are explained in this podcast.  In addition, a big win this week for precision or personalized medicine:  different symptoms and different genetic mutations are linked to different outcomes from different anti-seizure medications.

On Thursday, March 30th the Autism Science Foundation held their 4th Annual Day of Learning in NYC.  If you were not able to attend and can’t wait for the videos of the talks, this week’s podcast attempts to summarize what was presented.

A list of the talks are:

  • Autism Research: Where Are We Now? – Dr. Wendy Chung (Simons Foundation)
  • Housing Options for Adults with Autism – Amy Lutz (EASI Foundation)
  • Improving Communication Between Parents of Children with Autism and Teachers – Dr. David Mandell (University of Pennsylvania)
  • Developing Clinical Biomarkers – Dr. James McPartland – (Yale University)
  • Understanding Modifiable Autism Risk Factors – Dr. Craig Newschaffer (Drexel University)
  • Helping People with Autism Develop Practical Skills – Dr. Celine Saulnier (Emory University)
  • New Technologies to Improve Autism Diagnosis – Dr. Robert Schultz (Children’s Hospital of Philadelphia)
  • Understanding the Female Protective Effect – Dr. Donna Werling (University of California, San Francisco)

David Mandell’s presentation on parent/teacher communication was based, in part, on this publication:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4676744/

A new clue to autism found in fluid in the brain

Last week, another Baby Siblings Research Consortium Project (BSRC) published an intriguing finding which also has the bonus of being a replication.  Mark Shen, PhD, from the University of North Carolina at Chapel Hill found higher levels of extra axial fluid in the brains of infants who went on to later be diagnosed with autism, and even higher levels in those with severe autism symptoms.  Extra-axial fluid is also called cerebrospinal fluid, the fluid that holds the brain steady in your head.  Other functions of extra-axial fluid and what this means on how it may contribute to autism risk are described in the podcast.  He not only explains the findings, but conveys what families should know about them and how they can help with early identification of ASD.

Happy MLK day – a day when we recognize a man for his contribution in justice, tolerance, equality and service, I highlight a supreme court case which affects how those with special needs are fighting for justice and equality.   Also, over the holidays, Dr. Connor Kerns from Drexel University published how a new tool to diagnose anxiety in those with autism was validated, setting the stage for its use by physicians and clinicians who don’t have a lot of experience with autism to help better understand the symptoms of their patients.
