The Diagnosis Fits
Deborah Blum, director of the Knight Science Journalism Program at MIT and the author of The Poisoner’s Handbook, says the carbon monoxide explanation fits.
Blum explains, “You might get headaches, you might feel a little groggier than usual. And depending on the chronic exposure, you can even become mentally-off, cognitively-impaired in some ways.” And Blum adds that, because carbon monoxide poisoning involves oxygen deprivation to the brain, it is possible to hallucinate.
