I read a story, wish I could find the link but can't, that at the same time as these "attacks" were appearing there was an ongoing special program at the CIA involving agents taking some kind of experimental nootropic. I guess the idea was to create some kind of super agents. The story suggested a link to the reported attacks, that the symptoms were actually an unintended result of the nootropics. I see no mention of that theory in the comments here. Anyone else see that story?
