Hey Ricardo, this is the author of the article. Not sure how carefully you read it. The editorial accompanying the JAMA paper, plus letters to the editor and analyses in other journals all criticized the original paper as not showing evidence of "brain damage." Leading physicists likewise say it's impossible for microwaves or ultrasound to cause brain damage. Plus, even if they had suffered actual concussions, most should have recovered in a matter of weeks at most. But while everything about the case is inconsistent with a physical attack, it's entirely consistent with functional or psychogenic disorders. You gotta check out the videos online of people with functional movement disorders to see how bizarre and powerful these things are. It's not like a kid whining at 8 am on a school morning, "I feel sick! I wanna stay home!" This shit is real and, as another person commented below, there are many cases in which fuel is added to the fire by well-meaning doctors and alarming press reports. The real "what ifs" come from the State Department insisting it was an "attack" based on zero evidence and despite at least six visits to Cuba by the FBI. Not that politics would ever enter into U.S.-Cuba relations.
