Alleged “Sonic Attacks” at Cuban Embassy Shrunk Victims’ Brains, Study Suggests

Between 2016 and 2018 a number of US and Canadian diplomats working at an embassy in Havana, Cuba, reported symptoms like headaches, nausea and memory loss after hearing mysterious noises. The phenomenon became known as the “Cuban Sonic Attacks”, but Havana authorities have so far denied any wrongdoing. However, a recent study suggests something did affect the diplomats, as dozens of them showed structural changes to their brains, such as a 5 percent shrinkage.

Published in the Journal of the American Medical Association, the disturbing study analyzed advanced MRI scans of the brains of 40 diplomats that reported strange symptoms while being stationed in Havana, and compared them to those of 48 healthy people with similar ages and ethnic backgrounds. Researchers at the University of Pennsylvania found that the whole white matter volume -areas of the brain central nervous system that affects learning – of the affected diplomats was roughly five percent smaller than that of healthy individuals. Authors added that connectivity differences in the brain’s auditory and visuospatial areas were also noticed between diplomats and control participants.
