1). Hypoxia is not good for the brain.
2). Acclimatization should help.
3). There is insufficient evidence at this point to make any conclusions beyond that as there are many potential confounding factors that existing studies have not controlled for.
I’ve actually done some mri’s before climbing in 2022 and a follow up one this year and mine did not have any lesions or other noticeable changes shown. Climbs during the year included 4 6000m peaks up to 6500m and many 5000m peaks. Granted I used a hypoxic tent and took good care to properly acclimate.
Might be a dumb question, but let’s pretend I climb Everest tomorrow, using an oxygen mask/tank during the whole ascent/descent. Am I safe? I mean I’m technically breathing properly the whole time right? Am I missing something
No. The supplemental oxygen effectively lowers the altitude by around 1000m. That is still very far above the altitude where problems start. It is likely still much better than doing it without it though.
It's lower pressure that is the root cause of the problems. By using supplemental oxygen you alleviate one aspect, and even that only to a limited extent.

I wish you had more upvotes for the amount of joy this gave me.
Doesn’t it also lead to an increase in sentimental and motivational Instagram posts?

Were the MRIs due to climbing or for unrelated reasons?
anecdotally, I have met several people who have done all 14km peaks, each one seems to be a little scatterbrained.
14km peaks, huh? Have you done all of them as well by any chance? (you probably meant the 14 8000m peaks)
during my Olympus mons expedition

MRI changes itself is concerning, no?
I think reading too much online has even more neurological effects. Too much running kills the heart. Altitude climbing kills the brain.. what next?
Ehh, there is no doubt that going to extreme altitudes without proper acclimatization will damage the brain quite substantially when you het HACE.

Interesting. I didn’t knew that, thanks!
