This week saw two studies advancing a new type of animal model for autism:  the monkey.  Environmental factors had been studied using this model, but this week saw the very first genetic model of autism in a monkey that also demonstrates features of autism.  At the same time, another study published data on a new test to study autism in the monkey, the monkey Social Responsiveness Scale which, when further validated, will help show whether or not this new monkey model of autism symptoms is the real deal.   Can this advance knowledge of the causes like – as we heard this week – obesity and diabetes?  Too early to tell, but it’s two steps in the right direction.
