Autism – ASF Weekly Science Podcasts

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 … Continue reading "What the h**l is an induced pluripotent...

Since the ASF policy statement on marijuana for the treatment of ASD was published this summer, there have been some new scientific studies that may be of interest to families.  As it turns out CBD has opposite effects in the brains of people with autism compared to those without autism, meaning that it is absolutely … Continue reading "The latest on marijuana and autism across the globe"

Genetic testing for autism spectrum disorders is not just about finding the gene.  So many genes have been found that genetic testing allows families who have a rare genetic disorder to find each other, support one another, raise money for research and train physicians to better help their community.  While genetic testing isn’t always pushed, … Continue reading "Praise for genetic tes...

The question of whether or not autism is a difference or a true dysfunction in brain development has been debated for years.  A new study from Canada demonstrates that within an autism diagnosis, there is less of a difference in symptoms in the last 5 years than there was 30 years ago.  This raises a … Continue reading "Autism: Difference or Dysfunction?"

Did you know that in addition to the DoD’s support of the military, they all have funded $65 million in autism research?  This podcast discusses some of their programs and how they support military families and benefit the autism community. Want to read more about what they fund?  There’s a list here:  https://cdmrp.army.mil/search.aspx

This week is focused on what happens in schools, including classification, service receipt and new interventions.  How an educational classification translates to a clinical diagnosis, how and what factors are important in receiving services, what teachers think about repetitive behaviors and finally, a new intervention that can be delivered by therapists in school or mental … Continue readi...

There is demonstrated genetic overlap between many neurodevelopment disorders including  ASD, ADHD, and schizophrenia, and now there is data showing similarities in the structure and size of the brains in people with autism and those with ADHD.  These differences depend on how severe social difficulties are, but the similarities are seen with ASD and ADHD, … Continue reading "Autism spectrum...

A full transcript of this podcast episode can be read on the ASF blog here. Researchers at Mount Sinai led by Alex Kolevzon are running a clinical trial of the compound insulin-like growth factor 1 (IGF-1) for children with idiopathic autism. Dr. Kolevzon’s team previously demonstrated the safety and feasibility of IGF-1 in treating Phelan-McDermid … Continue reading "Can IGF-1 treat a...

Two new studies came out this week that implicates the role of the endocrine system in autism.  The endocrine system which regulates hormones in your body, also has a key role in brain development early on in fetal and child development.   PCOS is a metabolic condition and DDT is a toxic chemical banned years … Continue reading "What are PCOS and DDT, and what do they have to do with autism?...

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 … Continue reading "PMS:...

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. … Continu...

Using resources from the Autism BrainNet, researchers from UC Davis show specific brain changes in an area called the amygdala in autism.  The amygdala is associated with fear, emotion and anxiety in people with autism.  But because they can look at the brain directly,  the actual number of neurons in the amygdala can be counted … Continue reading "Here’s to understanding why people wi...

Sometimes treatment targets come from the places you wouldn’t expect.  This week, three new studies on the biological and sometimes, behavioral, effects of three commonly used compounds used to treat high cholesterol, edema, and angina were studied in people with autism.  Instead of focusing on just the behavior however, these studies took the approach of … Continue reading "Commonly u...

One of areas of genetic interest of autism is a region of chromosome 15.  Only about 3% of people with autism have the mutation, but 80% of those with the mutation have autism.  It is so important that people with duplications of this area have formed their own advocacy group called the Dup15 Alliance.  I was … Continue reading "Chromosome 15-apallooza"

Yes, another type of mutation in autism was revealed this week.  Those that are evident after the sperm and egg meet to form the zygote but still very early, during embryonic development.  Because it occurs after the original zygote is formed, the mutation is not found in every cell or every region of the body, … Continue reading "Post zygotic mutations in autism: what you need to know"

Last week, investigators with the Autism Treatment Network published a long awaited study on the differences between the DSM IV and DSM5.    Other studies had relied on information on old pieces of paper to judge whether or not someone who met criteria under DSM IV would be now diagnosed with DSM5 criteria.  This study, … Continue reading "A different type of autism?"

This week two important studies which examine early influences of language development are explored.  First, we are lucky that Dr. Aaron Shield from Miami University joined to explain why studying children who are deaf and have autism, as well as parents of deaf children, are important for understanding language development.  He explores how autism is … Continue reading "The Young and the De...

Happy 4th of July weekend.  This week’s podcast is devoted to the studies in the past few months focusing on autism treatments that didn’t make it into the regular weekly roundup.  They include data that shows promising results (peer networks and iPads) as well as those that didn’t do as well as hoped (social skills).  There … Continue reading "A 4th of July quickie on new...

In order to ensure that researchers have enough brain tissue to understand autism spectrum disorders, the education and outreach campaign is being expanded past families to doctors and professionals that have access to tissue.  One of these groups is neuropathologists.  At their annual meeting this past week in Los Angeles, and entire afternoon was spent … Continue reading "Brain tissue: wha...

This week, autism lost a pioneer and advocate for autism research:  Isabelle Rapin, MD, a neurologist from New York’s Albert Einstein University.  The first part of the podcast is a brief summary of her accomplishments.  The second part is an study called “how to keep your child out of the hospital”, presenting a recent study … Continue reading "Memorial Day Memoriam: Isabe...

Two studies of importance came out this week.  The first looked at the interactive effects of genetic mutations called copy number variations and air pollution.  Previously, ozone was not listed in the factors in air pollution that increased risk for autism.  But combine it with copy number variations – now the two together dramatically increase … Continue reading "Internet addiction i...

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 … Continue reading "What is the focus this week? The unsung heroes of grandp...

On Monday, the much anticipated MSSNG study which analyzed the entire DNA sequence of over 5000 people with autism was published.  The press release can be found here.  In it, the researchers found even more genes of interest to autism.  Also, those with more of a specific type of mutation, copy number variations, had worse autism … Continue reading "Who could have thought the genetics of au...

The brain is developing even after birth.  So interventions that are given very early have the best chance of remolding and rewiring a brain with autism to prevent autism related disabilities.  This week, a group from the University of London, Duke University and University of Washington measured brain activity during tasks that required social attention … Continue reading "The infant brain...

This week the Infant Brain Imaging Study, or IBIS, published it’s 2nd study on the emergence of changes in the brains of individuals with autism.  While red flags for autism can be seen early, a diagnosis of autism is not typically made until after 24 months of age. Using a baby sibling research design, scientists … Continue reading "When can you see autism in the brain?"
