This one’s for the girls

This week, Drs. Casey Burrows from @UMN and Shuting Zheng from @UTexas discuss a new paper looking at sex differences in autism features from 20-40 months of age. A new analysis done with data from the Baby Siblings Research Consortium concludes that, early in life, girls with autism show differences in some autism features (like joint attention) compared to boys. There are many reasons for this, including that boys and girls are just different, period. However, it adds to mounting data which may help explain why more males are diagnosed compared to females. More research needs to examine how girls and females present, what symptoms are harder to observe in females andy why, and most importantly, sheds insight how girls and females with autism need to be specifically supported.

What works and does not work for wandering and sleep

This week a new study showed that kids with autism wander as early as toddlers, so parents keep a close eye on your kids no matter what their age.  Medications do not work, but behavioral interventions do seem to help.  This podcast gives some examples.   Also, another study shows the efficacy and safety of melatonin for helping kids with ASD fall asleep and stay asleep, even after 2 years.   Melatonin may not be the magic bullet we need for sleep problems, but it doesn’t seem to hurt either.

Nobody puts babies in a corner

Nobody can dispute that research to better understand autistic adolescents and adults is lacking.  However, scientists continue to make important scientific discoveries in infants and toddlers with autism.  These infants and toddlers eventually become adolescents and adults, so identifying critical periods of brain development that influences behavior, what to say to parents and when, and how to  engage the entire community to better serve infants and toddlers is still needed.  This week is an update on the activities of the Baby Siblings Research Consortium (BSRC), including a paper that ties in activity of different brain regions at 1 year olds, to stereotyped behaviors and insistence on sameness in 2 year olds.  The research of the BSRC is directly applicable to families affected by autism at all ages.

A conversation with Clare Harrop about autism in boys and girls

Recently, Clare Harrop from University of North Carolina at Chapel Hill published two papers which help explain the differences between boys and girls with autism, at least in kids and toddlers.  She graciously agreed to talk with us about these findings and what it means for better identification and diagnosis of girls with ASD, and where future research is needed.  Thank you to Dr. Harrop for this insight and for your work in this area!

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.
