The point you are making about mass hysteria is appreciated, but often patients really do suffer from something that turns out to be real. I am a "Havana syndrome" skeptic, but I do think the other examples are cut from a different cloth. The first two examples that you've cited are great. Those people were dismissed at the time — only for scientists to find evidence decades later after many deaths. re: gulf war syndrome > Studies have consistently indicated that Persian Gulf War syndrome is not the result of combat or other stressors and that Gulf War veterans have lower rates of post-traumatic stress disorder (PTSD) than veterans of other wars. > In 2022, researchers led by Robert Haley, MD at University of Texas Southwestern Medical Center found that exposure to sarin nerve gas in soldiers who had a particular genetic mutation that prevented them from breaking down the nerve gas is likely to be responsible for the syndrome.[18] The findings and an editorial by two leading epidemiologists were published in Environmental Health Perspectives.[19] re: 9/11 https://en.wikipedia.org/wiki/Health_effects_arising_from_the_September_11_attacks https://en.wikipedia.org/wiki/Health_effects_arising_from_th... > More people have died from illnesses caused by 9/11 than during the attack itself.[3][4] > Much of the thousands of tons of debris resulting from the collapse of the Twin Towers was pulverized concrete, which is known to cause silicosis upon inhalation. The remainder consisted of more than 2,500 contaminants,[7] more specifically: 50% non-fibrous material and construction debris; 40% glass and other fibers; 9.2% cellulose; and 0.8% of the extremely toxic carcinogen asbestos, as well as detectable amounts of lead and mercury.[8] There were also unprecedented levels of dioxins and polycyclic aromatic hydrocarbons (PAHs) from the fires which burned for three months.[9] Many of the dispersed substances (asbestos, crystalline silica, lead, cadmium, and polycyclic aromatic hydrocarbons) are carcinogenic; other substances can trigger kidney, heart, liver and nervous system deterioration
