However, the US medical research agency stressed that despite its findings, the unexplained ailments "are very real"

The findings do not match results from a 2019 research by University of Pennsylvania, which showed some subtle brain changes in those affected

First reported in the Cuban capital Havana in 2016, the syndrome results in vertigo, headaches, cognitive dysfunction and ear-ringing

Since then, US foreign service and intelligence personnel have reported enduring such symptoms across the world
The exact cause of the syndrome remains elusive, with possible links to high-frequency microwave emissions
