This study is particularly concerning. I wonder if the “healthy” people he studied were of the same age.

Also, it mentions he examined only former pilots and cabin crew who “experienced complaints.” What about the pilots/FAs who did not experience complaints? Shouldn’t they be tested as well to check their brain activity?

Perhaps the brain issues in the selected group is not due to chronic exposure to fumes, but rather some other neuro issue. If they were retired flight crew they must be high in age. One can hope.
