Cuba: “Havana Syndrome” symptoms identified in Canadian tourist who visited Cuba

A case study is detailing the strange symptoms a Canadian woman experienced shortly before getting on a flight home from vacation in Cuba. The bizarre illness appeared to be in line with the unusual sickness experienced by American and Canadian diplomats in the Caribbean country, which has been referred to as “Havana Syndrome”.

The study published in JAMA Neurology describes how the 69-year-old woman started feeling unwell with “generalized weakness, increased sweating, severe nausea, and vomiting,” two hours before her flight was set to depart. While on the plane, more strange symptoms developed, including lethargy, vomiting, and urinary incontinence. Once back in Canada, she was sent to emergency, where she was “stuporous and required intubation”. The case study notes that the woman had no allergies and had nothing concerning in her medical history.

Most of the woman’s test results came back normal, except a CT scan, which revealed her globus pallidi was denser then normal on both sides. That’s the part of the brain that controls conscious movement.
