What is Havana syndrome?
The medical mystery named for the Cuban city where U.S. diplomats first
experienced sudden, debilitating symptoms in 2016 has been reported by
Americans serving in several other countries.
Acute symptoms (often occurring suddenly) may include
- Loud sounds (Sometimes described as chirping, clicking, or screeching) and
pain in one or both ears; many felt the sensations came from a particular
direction or were felt when in a specific location.
- Tinnitus, hearing loss
- Intense pressure or vibration inside the head
- Difficulty with memory or concentration
- Visual disturbances
- Nausea
- Unsteady gait, loss of balance, vertigo/dizziness
Chronic symptoms (can last weeks, months, or longer) may include
- Headache
- Impaired concentration, memory loss
- Insomnia
- Depression

No definitive cause has been found, but scientific studies have noted many of
the acute symptoms are consistent with exposure to directed radio frequency
(RF) energy. One theory posits the use of RF energy by a U.S. adversary as a
weapon or a tool of espionage.
