Whatever was behind the 'sonic attacks' experienced by US government personnel in Havana, Cuba, starting in late 2016 remains a mystery -- but a new study published Tuesday looks inside the workers' brains for clues.
Whatever was behind the"sonic attacks" experienced by US government personnel in Havana, Cuba, starting in late 2016 remains a mystery -- but a new study published Tuesday looks inside the workers' brains for clues.
MRI brain scans from 40 patients -- 23 men and 17 women -- showed variations in brain structure and functional connectivity, which measures relationships among different brain regions, when compared with 48 other adults. The scans were taken between August 2017 to June 2018."There were group differences all over the brain," said study author Ragini Verma, professor of radiology and neurosurgery at University of Pennsylvania's Perelman School of Medicine.
Doctors remain baffled, while Cuban officials have vigorously denied that there were any targeted attacks on diplomats in Havana and said their symptoms could have been caused by other factors.Meanwhile, more than a dozen Canadian diplomats who experienced similar symptoms while posted in Cuba are suing their government for millions.Officials have looked into similar cases in China.
