"Havana Syndrome: Pentagon Confirms US Defense Official's Symptoms at 2023 NATO Summit Linked to Russian Spy Unit"

A senior Defense Department official experienced symptoms similar to those of "Havana syndrome" during the 2023 NATO summit in Vilnius, Lithuania, with the Pentagon confirming the incident. The cause of the syndrome is still under investigation, with a recent "60 Minutes" report suggesting Russian involvement. The Office of the Director of National Intelligence found it "unlikely" that a foreign adversary was responsible, a conclusion supported by the State Department. The Pentagon has established a registry for reporting such incidents, while a study by the National Institutes of Health found no brain injuries or degeneration among affected U.S. diplomats and government employees.
