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 Monday.
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.
Symptoms of the mysterious ailment, first reported by U.S. embassy officials in the Cuban capital Havana and later afflicting diplomats, spies and other personnel worldwide, have included hearing noise and experiencing head pressure followed by headache, migraines, dizziness, and memory lapses.
