An update on why there are fewer autistic females compared to males

This week, special podcast correspondent #MiaKotikovski summarizes new research on the increasing prevalence of autism, with a focus on females. While the number of diagnosed females is increasing faster than the number for males, females assigned at birth still are less likely to receive a diagnosis than males. Additional evidence points to females having more genetic mutations and lower cognitive ability, so the questions remain: Are there females with autism who are just not getting diagnosed despite having all the autism features? Why not? Does autism in females “look” the same as autism in males? What sets them apart? These articles are all featured in the year-end highlight of research, so this is the time to get a deep explanation of the latest in sex differences in #autism.

Autism diagnosed in school age, and does early intervention make a difference?

Thanks to a Facebook follower, this week’s podcast highlights a new systematic review on Early Intense Behavioral Intervention. This systematic review, however, is not different from one published 5 years ago, because the nature of early interventions have changed so much that they no longer fit into the same criteria. While the rankings are disappointing, the findings do not reflect the ways in which newer interventions are being selected, delivered and studied. Also, we always hear about early diagnosis helping with early intervention. But what about kids who are not diagnosed until they reach school age? They have a different profile of ASD and may be a different subgroup of autism altogether.

Autism diagnosis in adulthood

While still rare, there are cases where an autism diagnosis is not made until adulthood.  Why have these people been missed and what do they need?  How did they go for so long without anyone recognizing that they needed help?  A new study from the lab of Dr. Francesca Happe in the UK investigates the characteristics and features of people who were referred for a diagnosis after 18 years of age.  Hear more about how they managed in this week’s podcast.

A focus on the siblings of people with ASD

Two studies recently add to an ever growing literature around undiagnosed siblings of individuals with autism.  While in autism features there is evidence of the “broader autism phenotype” in female siblings, there is no evidence of elevated sensory symptoms in those with a brother or system with autism.  The more we understand about the psychological and psychiatric features of siblings with autism, the more they can be supported to deal not only with their siblings challenges, but with theirs as well.
