The psychosis was due to bromism (bloodstream bromine buildup to toxic levels) due to health advice to replace sodium chloride with sodium bromide in an attempt to eliminate chloride from his diet. The bromide suggestion is stated as coming from ChatGPT. The doctors actually noticed the bromine levels first and then inquired about how it got to be like that and got the story about the individual asking for chloride elimination ideas. Before there was ChatGPT the internet had trolls trying to convince strangers to follow a recipe to make beautiful crystals. The recipe would produce mustard gas. Credulous individuals often have such accidents.
