Electromagnetic radiation is studied all the time, and nothing ever comes out of it. So that's gonna be a dead end.
SSRis... while likely too many people take them, I don't think every chronic disease sufferer out there takes them. In general worth investigating their effects more, but I don't think this will help his cause.
I have my doubts about vaccines, since I doubt there's any of them not used in other parts of the world. But if they think they can find a particular unique thing about how US vaccinates people that maybe has an effect, I'm not against doing studies.
My bet would be on processed foods and maybe pesticides.
