There were reports of brain anomalies on MRI scan in "Havana Syndrome" victims. What would we make of those?
Also it would be pretty weird if people who have neurological symptoms don't have brain anomalies, given that this kind of goes hand-in-hand regardless of what the cause of either one is. Migraine patients often have neurological anomalies in the brain, doesn't mean someone caused them with a laser. People who experience Havana Syndrome style symptoms might be predisposed to overreact to, in this case apparently crickets, because they have some neurological issue to begin with.
But in answer to your question, it would depend on the quality of the medical reports. It doesn't seem, so far, that the science can be widely replicated or is clearly pointing to maliciously directed activity. I believe there is a Canadian study that suggests exposure to chemicals. I don't know how that study has been received by peers.
