Two new interesting studies have come out – one focused on the rate of autism and the other on a possible hormone that is linked with social difficulties.
The rate of autism has been continuously increasing over the years, with the latest figures showing that 1 in 68 children are diagnosed with autism. The rate increase hasn’t been attributed to anything specifically, and questions are mounting as to what has caused the increase. A new study, however, may have provided an answer – the rate is likely due to a change in the way children are being classified and diagnosed. A team from Penn State University looked at special education enrollment and found that the increase in students designated as having autism could be offset by nearly equal decrease in students diagnosed with other intellectual disabilities often seen along with autism. So conditions that were once likely classified as something else are now being identified as autism, probably due to broader awareness.
Another study showed that children with autism who struggle with “theory of mind” – the social skills that deals with the realization that other people have different perspectives, feelings and experiences – have lower vasopressin levels. Vasopressin is a hormone that helps regulate blood pressure and may play a role in social behavior. There are currently no medications that effectively treat social deficits, so this could prove a target for future focus.
