The article says the team at the Center for Brain Injury and Repair at the University of Pennsylvania didn't think it was mass hysteria:

The neurologists at the University of Pennsylvania found that some explanations for the Havana Syndrome, including mass hysteria and group psychosis, were highly unlikely. Many of the patients didn’t know each other, their performance on these tests could not have been faked, and they did not wallow in their pain. In fact, according to the study, they were desperately trying to get better and “were largely determined to continue to work or return to full duty, even when encouraged by health care professionals to take sick leave.” The study also concluded that these injuries were likely not caused by exposure to chemicals, since no organs other than the brain were involved. Nor were they likely to have been the product of a viral infection, the doctors said, because these patients did not display associated symptoms, like a spiking fever.

Ok, cool. So then:

1. Directed Energy Weapon - 40% Chance

2. In-house Embassy Comms Equipment - 30% Chance

2. Pesticide Spraying - 25% Chance

3. Psychosomatic - 5% Chance
