In late 2016, an official at the US Embassy in Cuba woke up in the middle of the night with a ‘severe pain and sensation of intense pressure in the face’. He also felt ‘a loud piercing sound in one ear…and acute disequilibrium and nausea’. A report by the National Academy of Science reported the official was left with, ‘symptoms of vestibular and cognitive dysfunction’, or in simpler terms, left totally dazed and confused.
