Scans on US diplomats in Cuba show ‘something happened to the brains’

Brain scans of about 40 US diplomats injured in mysterious circumstances in Cuba reveal visible differences compared to those in a control group, researchers who analysed them said on Tuesday.

The study, published in the Journal of the American Medical Association and led by professors at the University of Pennsylvania, does not draw any conclusions about the cause of the symptoms suffered by the diplomats from late 2016 into May 2018.

But the MRIs of the patients confirm that "something happened to the brains of these people," Ragini Verma, a professor of radiology at UPenn and co-author of the study, told AFP.
