Autism Science Foundation Weekly Science Report

This week, Melissa Scott from Curtin University, a partner in the international policy brief on employment for people with autism, discusses the first paper out of this collaboration:  a scoping review of the existing research out there on employment practices.  Surprisingly, there was one crucial element missing as a focus in all the intervention studies  –  the environment.  Dr. Scott discusses what else was learned from this scoping review, and how the findings can help people with autism not just obtain, but maintain employment, through constructive policy.   ASF is a proud partner on this policy brief, and Curtin University has been an amazing collaborator.

Last weekend, the Phelan McDermid Research Foundation held their biannual family conference in Dallas Texas.  People with Phelan McDermid Syndrome, or PMS, suffer from seizures and intellectual disability, and about 70% have an ASD diagnosis, Over 150 families from across the world came together to show each other support, learn about housing options, receive genetic counseling, talk to experts and hear the latest research.  ASF attended the meeting and this podcast is a short summary of what was presented by researchers at the conference.  This syndrome is caused by mutations of the SHANK3 gene, which is present in about 1% of people with autism, making it the most common single genetic influence of ASD.  Even if you don’t have a mutation in SHANK3, many of the issues affecting those with PMS may apply to you.  To learn more about the conference, click here:  https://www.pmsf.org/ifc/

Two studies came out recently which used a randomized design to show how interventions can be delivered in the classroom.  They both focused on making sure they were implemented properly and that teachers received the support they needed to help kids in the classroom.  It isn’t just about writing a manual, it’s about making sure teachers know how to deliver it.

Thanks to a Facebook follower, this week’s podcast highlights a new systematic review on Early Intense Behavioral Intervention. This systematic review, however, is not different from one published 5 years ago, because the nature of early interventions have changed so much that they no longer fit into the same criteria. While the rankings are disappointing, the findings do not reflect the ways in which newer interventions are being selected, delivered and studied. Also, we always hear about early diagnosis helping with early intervention. But what about kids who are not diagnosed until they reach school age? They have a different profile of ASD and may be a different subgroup of autism altogether.

There are relatively few studies using self-report findings on standardized measures from people with autism.  Part of the reason for this is because there aren’t that many of these instruments to begin with.   Scientists are working on that.  But this week, a group from the UK took the existing data from smaller studies using the the Ritvo Autism Asperger Diagnostic Scale (which can be found here:  https://www.aspietests.org/raads/) to look at sex differences.  They found subtle differences between males and females on their language and sensorimotor features.  This indicates males and females experience autism slightly differently.   In addition, a different study interviewed people with autism at different ages to ask how symptoms changed over time and found that features of autism peaked in middle adulthood.  However, close family members, friends or caregivers didn’t always see it that way themselves.  This reiterates the need to collect information from multiple people – including people with autism – to provide better services and supports.

Due to popular demand, this podcast is dedicated to the International Classification of Functioning, or ICF.  This is a tool used to measure functioning in people with not just autism, but across individuals.  As the expert guest, Soheil Mahdi, describes in this podcast, it isn’t about replacing a diagnosis of autism, but complementing the diagnosis with a description of ways the person is functioning in society, what strengths they have and how it that may identify opportunities for autistic individuals.  Soheil is a fellow at the Karolinska Institute and ASF is collaborating with him on the employment policy brief.  Thank you for suggesting this topic for a podcast!

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:

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.

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.
