A U.S. government research team found no significant evidence of brain injury among a group of federal employees reporting symptoms of the “Havana syndrome” ailment that emerged in 2016, according to studies published in a medical journal on March 18.
The National Institutes of Health (NIH) researchers also found no differences in most clinical measures between a group of 86 employees and their adult family members reporting unusual health incidents and a matched group of healthy volunteers who had similar work assignments.
