(CBS NEWS) — According to medical records reviewed exclusively by CBS News, a U.S. doctor who evaluated American and Canadian diplomats working in Havana diagnosed them with conditions as serious as mild traumatic brain injury, and with likely damage to the central nervous system.
The diplomats complained about symptoms ranging from hearing loss and nausea to headaches and balance disorders after the State Department said "incidents" began affecting them beginning in late 2016. A source familiar with these incidents says officials are investigating whether the diplomats were targets of a type of sonic attack directed at their homes, which were provided by the Cuban government. The source says reports of more attacks affecting U.S. embassy workers on the island continue.
The doctor, one of several who reviewed their cases, included a warning in the medical records about the health risks of future exposures. The diplomats underwent comprehensive audiological evaluations and a battery of other tests.
