Rarely can individuals with autism be studied more than once – but a new study tracks how cognitive and adaptive behavior changes over time.  What researchers in the British Autism of Infant Siblings, or BASIS found, was that family history of autism meant as much to cognitive and adaptive behavior than an actual autism diagnosis.  This calls for close monitoring of siblings of those with autism, regardless of whether or not they had a diagnosis.  Also, investigating psychiatric issues in children may underestimate their prevalence because many psychiatric issues do not emerge until the teenage years, so Kaiser Permanente looked at medical and health records of those with autism at 14-25 years to see what other issues they were facing, and the findings are both sobering yet maybe a little comforting.

Commonly used drugs that may help autism

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 examining them from the behavioral side, determining if there was a biological reason why these compounds should be helping people with autism.  This means autism research has turned a corner – it’s not just about behavioral improvements, but about how the drug is working in the brain.  Also, a fun study about social media in people with autism.  They don’t just use it like the rest of us, it actually makes people with autism happy.

Here are the studies included in this week’s podcast:

Autism symptoms in girls with anorexia

This week summarizes some new studies looking at autism traits and autism diagnosis in girls with anorexia nervosa.  While the two disorders may seem different on the outset, they do share some behavioral features.  Unfortunately, most studies look at autism in those with anorexia, not the other way around.  However, what is known is that there is not only higher levels of ASD traits in girls with anorexia, about 10% of girls with anorexia also have an autism diagnosis.  This number can only be trusted if you look at both standardized observation instruments AND parental report.  Studies determining the rates of eating disorders in autism are desperately needed for better treatment of symptoms.

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.
