On December 12, 2018, physicians at the University of Miami published a scientific study concluding that the U.S. diplomats in Cuba who have reported certain medical problems over the last two years suffered damage to the part of the inner ear responsible for balance. 
Dr. Michael E. Hoffer, the director of the university’s Vestibular and Balance Program and lead author of the study, said, “These people were injured. We’re not sure how. The injury resulted in ear damage and some trouble thinking.”
Dr. Hoffer added, “What we noticed is universal damage to the gravity organs in the ear. The ear has a bunch of different balance organs — and two of them are gravity organs — and those are damaged in everyone.” After suffering the damage, he said, the patients’ bodies spend so much energy trying to stay balanced that it wipes them out.“That’s very fatiguing. And it doesn’t leave a lot left over to remember where you put your keys.”
To date the U.S. has not identified any known cause for these injuries. The University of Miami study said, “it would be imprudent to exclude any potential directed or non-directed energy sources at this time.”
