Abstract
Havana syndrome cases increased in Cuba at the end of 2016 and early 2017, and the consequences ranged from minor to severe health concerns. In almost all affected individuals, symptoms like difficulty-concentrating, visual issues, brain-fog, memory problems, tinnitus, and sleep-related complaints were reported. Some initial studies pointed the causative possibility towards energy weapons, ultrasound, microwaves, microbes and chemicals. However, to date, no study has provided a comprehensive explanation of this sudden mysterious syndrome, and the root cause remains unexplained.
