Ignoring the obvious problems with the study design that others have pointed out, it does seem like an interesting concept. We see several stories a year discussing the links between air pollution and dementia, and also a link between more exercise and less dementia. so it makes some sense to me that there might be a link between decreasing lung function and increasing dementia. if the function of the HBOT is to increase the ability of lungs to oxygenate blood, maybe there is a subtle but important threshold of blood oxygenation that we don't understand well enough. note: I am not a medical professional at all, it just seems like there is a "lung function" commonality in several of these stories.
