I don't know why so many seem so eager to dismiss this as "all in their heads." Sure, some people might attribute their random pains and illnesses to "Havana syndrome." But the original reports were from intelligent, educated, responsible professionals with a lot of overseas experience, and apparently many of them were affected in their scattered homes, not in the embassy, and they displayed conditions that were medically confirmed.
Here's one theory that the problem is not sonic weapons, but pesticide exposure.
Maybe that's not right either. But medicine has been notorious for telling people who couldn't be easily diagnosed that they need a shrink, and who then turn out to be real victims of rare but real illnesses and conditions.
Other reports seem to have extensive detail.

Here's one theory that the problem is not sonic weapons, but pesticide exposure.
https://www.israel21c.org/israeli-researchers-crack-mystery-of-havana-syndrome/Between 2016 and 2018, about 40 Canadian and US diplomats and their families stationed in the Cuban capital mysteriously became sick. The so-called “Havana Syndrome” caused headaches, dizziness, loss of balance, nausea and difficulty concentrating and falling asleep.
The initial fear was that the Cubans were triggering the symptoms with some kind of sonic weapon.
Research conducted by Dr. Alon Friedman of Ben-Gurion University and colleagues at the Dalhousie University Brain Repair Center in Nova Scotia, Canada, points to a different culprit: overexposure to pesticides — in particular, fumigation to stop the spread of the Zika virus prominent around that time.
They found a correlation between the individuals most affected and the number of fumigations that were performed at their residences. Both the Cuban and Canadian authorities were fumigating more frequently than usual, according to records from the Canadian embassy.
By conducting brain scans on the affected individuals using MRI and magnetoencephalography (a functional neuroimaging technique for mapping brain activity), the multidisciplinary research team of 15, led by Friedman in Israel, concluded that exposure to cholinesterase inhibitors in organophosphorus insecticides was the probable cause. Cholinesterase is an enzyme required for proper nervous-system functioning.
Maybe that's not right either. But medicine has been notorious for telling people who couldn't be easily diagnosed that they need a shrink, and who then turn out to be real victims of rare but real illnesses and conditions.
