In this week’s podcast we explore autism and autism-esque symptoms in family members, particularly siblings.  Siblings can show mild features, called the broader autism phenotype, all the way to an increased risk of mental illness including emotional and behavioral problems, ADHD and tic disorder.  This week we revisit the study of a large number of siblings in Finland and a new project looking at milder impairments in a smaller number of siblings with an older brother or sister with autism.  Also – as a special treat, highlights from the DUP15 meeting in Maryland this past week.

Last week, the Autism Society (www.autism-society.org) held it’s 48th annual meeting in it’s 50th year of existence.  In addition to hearing an update on how people with autism and their families have benefited from autism research over the past decade, participants contributed to panels on experiences of adults, behavioral techniques, technology, the the history of autism.  On this week’s podcast, hear about two of the sessions – how to teach social interaction on the iPad and how to be an effective advocate.

This week’s podcast summarizes a new neural stem cell study and a recent review article on IGF-1 treatment in developmental disorders. IGF stands for Insulin Growth Factor and is essential for generation of new neurons, and shaping and health of existing neurons.  Patients with autism spectrum disorder are already starting to be treated with IGF-1, and now there is even more evidence validating it as a target.  If you are interested in participating in a research trial at Mt. Sinai School of Medicine using IGF-1, call the Seaver Center at  212-241-0961.

On Monday the 1st, a consensus statement from over 50 expert scientists was published that collectively emphasized the link between toxic chemicals and neurodevelopment disorders like autism, learning disabilities and ADHD.  In this podcast, we want to help you understand why this is relevant for autism.  If you want to learn more about this statement and read about specific actions that can be taken to minimize exposures to these chemicals, go to www.projecttendr.com.  We will also be having a live chat about it on July 11th at 2PM EST.

Oxytocin: hitting a small nail with a giant sledgehammer?

This week’s podcast is inspired by a new study in PNAS thatlooked at the role of methylation of the oxytocin receptor in social behavior in people without autism.  Together with studies of the brains of people with autism, it suggests that filling the brains with oxytocin may not be the best approach for treating social impairments.  Instead, compounds that turn on or turn off the genes that control oxytocin may be more appropriate, and it also may help explain variability in why some people respond to oxytocin treatment, and why others do not.   Also, scientific technology has a new way of studying the influence of the environment on brain development.

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.

As college and university semesters come to a close, new research is determining the factors that lead to success in college for the individuals with autism but without intellectual disability. They include: help with time management, relationships (both peer and romantic), self-advocacy and organizational skills. Students, parents and educators agree on what is needed, but institutions are struggling to make sure they are available.

Autism across the ages

Two studies from Sweden came out this week with the same idea: study autism across time, and focus on other things besides just autism. This podcast reviews both. The first examined quality of life in adults over the course of 20 years and the other followed preschoolers into school age. The results are consistent. That is, people with autism have high levels of psychiatric comorbidities which depended on a number of factors. Of particular importance is the role of intellectual functioning on outcome. These recent data are further evidence that while people with autism share struggles, those with ID may need to be considered differently in clinical care, housing, employment, and obviously intervention.

Those confusing folate findings explained

During IMFAR, a study was presented that showed that women with very high levels of folate during pregnancy showed an increased risk of having a child with autism. The media took this to mean that taking too many prenatal vitamins caused autism. ugh. This week, those findings are discussed. Also published this week is a well-designed, long awaited study which examines the theory that too little folate in the central nervous system is the culprit behind autism. Too little folate in the brain is not the culprit, and too much in the blood may be coincidental to something else causing autism. It’s important to have a balance so don’t hesitate to take a prenatal if you are trying to get pregnant.

Also, because you may be IMFAR’d out – we highlight the exciting findings that cognitive behavioral therapy for treating anxiety in people with ASD is not only effective in clinical settings, but in school settings. This has implications people with ASD in special needs classrooms who need treatments for anxiety.
