As one of the aformentioned caretakers I can attest that a certain narrowing of focus on one's own issues is part of the deal. I also have an autistic adult friend who is constantly dismayed by the focus on child autisim, so I can relate to what you are saying. The focus on children is likley caused by the medical siloing of patients into pediactric and adult. Also researchers may want to focus on harm reduction, ie by preventing or amelirating autisitic symptoms in children it is likley to also prevent the downstream effects to their nervous systems. But certainly if researchers want to get a better understanding of treatment efficacy, adults should also be included in trials. Our current diagnostic grouping of symptoms into an autisic spectrum is imperfect, I would be very supprised if autisim as we understand it today is caused by one thing. So if this research becomes a treatment it will likley only be benificial for a certain percentage.
