The infant brain on early behavioral intervention

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 following 2 months of very very very early intervention.  They found that the way the brain responded to social stimuli was more like those without an autism diagnosis.  This study shows a biological marker of brain function is altered after behavioral interventions that are intended to do just that – change the way the brain functions.

When can you see autism in the 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 showed increases in the size of certain areas of the brain between 6-12 months.  This opens up opportunities for even earlier diagnosis of ASD in the future.   Also, a group at Stanford shows the emergence and disappearance of co-morbid symptoms in autism, such as epilepsy, schizophrenia and ADHD, which are dependent on sex and age.  Together, these studies show that autism begins very very early and symptoms and behavioral and biological features change over time.

New science for those with little or no language

Even though more than 20% of people with autism have little or no language, research into ways to help this group have really been lacking.  Several efforts to not just understand the abilities and disabilities of this group started a few years ago and we are just starting to hear about what works and what doesn’t work to improve communication in those with little or no language.  This podcast summarizes the evidence, which points to combinations of things, rather than things in isolation, and peeks in on ways in which interventions can be better directed and made more effective.

The year 2016 was eventful for many reasons.  In this 20 minute podcast, we review some of the scientific discoveries that highlighted findings in causes, understanding, and treating ASD.  Featured more this year is studies on the sibling of individuals with ASD, so we are calling 2016 “The Year of the Sibling”  This review includes genetics, gene x environment interactions, diagnosis, the broader autism phenotype, and early interventions and the role of parent-delivered interventions in long term outcome.  It also highlights the important role of studying brain tissue from individuals with autism to better understand people with autism across the lifespan, including those with known causes and unknown causes of ASD.  We hope you find it informative – please send comments to ahalladay@autismsciencefoundation.org

Brain signals improve the efficacy of behavioral interventions

Biomarkers can help distinguish different types of features but this week they were used to predict who would respond to Pivotal Response Training, or PRT.  Researchers, led by Pam Ventral at Yale looked at how the brain responded to a social or non social situation as well as baseline features on standardized measures.  Remarkably, these brain signatures were better at standard behavioral assessments at determining who would respond most positively to PRT.  This study has enormous implications for personalized medicine approach and demonstrates how early studies in biomarkers many years ago have paid off for those with autism.

Hear what you missed if you were unable to attend the Seaver Autism Conference on September 25th!  Dr. David Skuse discusses “where are all the girls with autism”, summarizing evidence that some girls with high verbal IQ and autism might be missed, suggesting genes associated with high IQ may be protective against a diagnosis until adolescence.  Also, ASF grantee Dr. Jennifer Foss-Feig describes how biomarkers can be used to improve personalized medicine.  Finally, a summary and review of the new air pollution systematic review and meta analysis.  Limited evidence does not equal none, and air pollution is a real problem.  Here is a link to the paper:  http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0161851.  All in 12 minutes.

Intervention studies are about to get better

Studies looking at interventions in autism have been plagued with issues of what treatments will work best in what people, and use of instruments to detect change that were never designed for use in people with autism. Recently, a new instrument was developed to look at improvements in social – communication in autism. This the first of it’s kind and will lead to better interventions to help people with ASD. Also, new research is using biological markers of autism to look at the effectiveness of interventions. The findings are still early, but promising and will help find out what types of treatment are best in which people.
