When it comes to intervention, earlier is better

This week, we talk to Whitney Guthrie from Children’s Hospital of Philadelphia who spent the last 6 years conducting the gold-standard randomized control trial that demonstrates intervention for social communication skills at 18 months shows greater effects than intervention starting at 27 months. If you wanted evidence that earlier is better, here it is! Interventions and supports are important at any age, but the critical window of development between 18-27 months is particularly important for long term development.

The Pros of Prozac and the Placebo Effect

Two of the largest randomized control trials of Prozac as an intervention for restrictive and repetitive behaviors were published recently.  They both coincidentally found no effect on the core features of autism, nor clinician rated improvement.  What they did find is a big placebo effect.  That is the behaviors of the participants changed even if they thought they might be getting the medication, but were actually getting an empty pill.  This is a big problem in research in studying medications across mental health.  So why is Prozac so popular?  And when it comes to some features of autism, is the placebo effect so bad?

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.

Can people with autism lose their diagnosis?

Researchers have been studying a small group of individuals who were diagnosed with autism, then later no longer met criteria for diagnosis.  Most of these people received early intense behavioral intervention before the age of 3, and what is called “optimal outcome” by researchers is the exception, not the rule.  However, a new study explores where they are no longer showing symptoms, and where they still are.  Also, ASF postdoctoral fellow Aarthi Padmanabhan explains her data on the brain structure of girls and boys with autism.  A sneak peak:  girls are different than boys.
