Females with autism are different than males with autism in a lot of ways.  This week, researchers used twins to examine the differences between males and females with autism in their brain structure and how it’s associated with autism traits, not a diagnosis.  To do this, researchers in Sweden turned to twins.  As it turns out, females have more of a diversity of differences in brain changes compared to boys, supporting the female protective effect.  But how to females with autism feel?  As them!  A group in the UK interviewed over 20 women on the spectrum or their parents to find out what concerns them most and what they find most challenging.

Both articles cited this week are open access:

Happy President’s Day!  This week’s podcast is focuses on a topic that has been on the mind of families affected by autism:  autism and violence and victimization.  The studies reinforce 1) the lack of an association between autism and criminality, 2) the association of an autism diagnosis with being the victim of abuse.  This includes self report data, database analyses and assessment of people who cannot report their abuse.  This sobering podcast was posted today because gun violence is an issue at the forefront of this president’s administration.  While this podcast is not focused on gun violence, hopefully this data will reduce the misconceptions and stereotypes around autism and violence.

Autism spectrum disorders underneath a bigger umbrella: more data from the brain

There is demonstrated genetic overlap between many neurodevelopment disorders including  ASD, ADHD, and schizophrenia, and now there is data showing similarities in the structure and size of the brains in people with autism and those with ADHD.  These differences depend on how severe social difficulties are, but the similarities are seen with ASD and ADHD, but not OCD.   In addition, this week there are new depressing results from the Interactive Autism Network on unemployment and females with ASD.  The results may not surprise you, but they will upset you.

Infant motor issues and later autism diagnosis

Everyone knows the way to study infants with autism is through thorough testing of younger siblings of those with a diagnosis, who have a 15x greater chance of have a diagnosis themselves.   Through these methods, new ways of identifying and predicting autism  later on have been developed.  On this week’s podcast:   two very influential and recent papers on the study of motor issues in 6 month olds who go on to be diagnosed with autism, and those  who don’t have an autism diagnosis but have signs and symptoms of ASD.  Are motor issues related to an ASD diagnosis or ASD symptoms?  And what about core symptoms of autism like language?   Can early motor behaviors be used to predict who goes on to receive an autism diagnosis or has language problems?  What should parents do?  How should this influence an early intervention plan?  Learn more this week!
