"NIH Research: No Physical Evidence of Harm in Havana Syndrome Patients"
Originally Published 1 year ago — by NPR

Two rigorous government studies conducted at the National Institutes of Health found no unusual pattern of injury or disease in the brains of people with Havana syndrome, a mysterious cluster of symptoms experienced by government employees stationed in various countries. The studies involved more than 80 individuals and concluded that there was no evidence supporting the idea that the symptoms were the result of attacks by other nations. While the findings challenge the notion of targeted attacks, some experts believe that a more holistic assessment of individual cases is needed, while others suggest that counterintelligence may be the answer if there is indeed something triggering Havana syndrome.
