Science, a journal of the American Association for the Advancement of Science, on December 5 published an article about the results of a Cuban scientific committee’s study of the medical problems of 24 U.S. diplomats who had served at the U.S. Embassy in Havana. The Cuban committee’s 20 members are physicians, neurologists, acoustic scientists, physicists and psychologists.
The Cuban study concluded that the diplomats probably suffered a “collective psychogenic disorder” [disorder having a psychological cause, not a physical cause] and not a deliberate ‘health attack.’” Stanley Fahn, a neurologist at Columbia University, who has seen a summary of Cuba’s report, agrees that “it could certainly be all psychogenic.“
Another U.S. neurologist, Alberto Espay of the University of Cincinnati, who has read the Cuban report, said, “The combination of sudden onset of hearing loss, tinnitus, headaches, vertigo, nausea, insomnia, anxiety, and memory problems would have to be related to multiple lesions in both brain hemispheres.” This comment coincides with the nearly simultaneous report of U.S. physicians who had treated some of the diplomats that their patients had abnormalities in the brain’s white matter tracts that normally let different parts of the brain communicate with one another.
The committee lamentably was unable to obtain detailed medical data from the U.S. But it conducted audiometric tests on neighbors and domestic workers in the diplomats homes, examined environmental sounds and insecticides near the homes and recordings of certain sounds that were provided by the U.S.
One of the Cuban committee’s members emphasized that the findings were “provisional. If any evidence were available, they will be willing to revise their conclusions and they are eager to team up with U.S. scientists.
