Havana Syndrome

The US Senate this week voted unanimously to provide more medical and financial support for approximately US government employees suffering from a mysterious condition known as Havana Syndrome. Some 130 people have experienced symptoms, including nausea, headaches, vertigo, and, in some cases, debilitating brain injury after living working at the US Embassy in Havana, Cuba back in 2016 (pictured). But how can radio waves cause brain damage? We get answers from Darius Kohan who is a professor at NYU School of Medicine, and the Director of Otology and Neurotology at Lenox Hill Hospital.
