Seems I offended you. Not sure how/why, but sorry I did!
Do people die from hypoglycemia? Even today?
Also, while there are plenty of well-experienced diabetics on this site who certainly need no cajoling from me to manage their condition (Richard especially -- I'm not the least bit worried about him), keep in mind there are all sorts of people here -- newly diagnosed, youth, those that have ignored or neglected their disease, people in denial, etc. etc.
Unless you are claiming that hypoglycemia can not cause brain damage (which is not what the referenced article was saying), I'm really at a loss to see what you find objectionable to what I posted.
Finally, the published follow-up studies, and their conclusions, that you reference are precisely my point in saying we know very little -- in science, particularly medical science, that information is encouraging, but in terms of well-understood correlation/theory, it ain't squat.
That's the sort of thing that can lead to research to find out and develop a complete theory of metabolic behavior while hypoglycemic. The fact is, this sort of research simply hasn't been done. So, to a large extent we're operating based on personal experience, anecdote, and a small number of passive follow-up studies showing correlation.
Thin gruel for making definitive statements about the risks of hypoglycemia and neurological damage that people can rely on.
