Watershed moments in development

Autism diagnosis at 3 years of age isn’t something that happens suddenly. It evolves, there are deficits seen early on and markers that are evident prior to 3 years. Some of them are cascading events – with problems in one area like motor function, other behaviors like reaching, grasping, and learning about the environment and interactions with other people are stunted. Sometimes, these cascading moments lead to a loss of language. Early intervention can turn these early deficits around so that communication, learning and daily functioning are continually supported and instead of one trajectory, another can be reached. This podcast highlights studies that demonstrate that with data, and with theory. But it is never boiled down to one thing, despite early studies that screen time use is linked with an ASD diagnosis.

Internet addiction is a real thing and it is worse in kids with autism

Two studies of importance came out this week.  The first looked at the interactive effects of genetic mutations called copy number variations and air pollution.  Previously, ozone was not listed in the factors in air pollution that increased risk for autism.  But combine it with copy number variations – now the two together dramatically increase risk.  Ozone levels are something that can be reduced through legislation.  Second, the role of internet addiction is generally not acknowledged or appreciated, but a recent study demonstrated that people with autism show triple the rate of internet addiction compared to those without autism.  This is something that psychiatrists and psychologists should know about when they think about treatments and comorbidities of people with ASD.

Precision medicine presents: OXYTOCIN!!!

Overall, the scientific research examining the efficacy of oxytocin treatment in autism spectrum disorder has been mixed.  On a previous podcast, studies in the way the oxytocin receptor was turned on and off were explained which may account for variability in treatment response.  This week, two studies in Japan show that specific mutations in the oxytocin receptor product predict who will respond to oxytocin treatment and who will not.  Therefore, the oxytocin story is one of the first examples of using genetic findings to push better treatment on an individual level, otherwise known as precision medicine.
