This long term study reported in Scientific American shows strong evidence of permanent brain damage from ascending above 4,000m.Sep 27, 2007 at 10:42 am #1403862

whole article of study they take their data from.
Comments: Their data seems odd. In 12 experienced climbers their before and after MRI's were not different. How can they then claim that altitude caused the abnormalities?Oct 2, 2007 at 5:35 pm #1404353
Interesting article, Brett. Thanks for posting it, although about 30 years too late for me. That said, I find myself wondering where the boundary lies between brain damage that truly compromises an individual's cognitive and other brain driven functions, and brain damage that is detectable with advanced imaging but not manifested in decreased function. I say that because I, and a fair number of people I know personally, have spent considerable time above 4000 meters, both climbing(though not at an elite level) and backpacking. None of us have so far suffered any detectable loss of function other than the judgment required to stop going up high. I guess we all sort of have the attitude that nobody gets out of here alive anyway so…..Oct 2, 2007 at 6:14 pm #1404357

I'm screwed… I'm living at 9,200 feet in the San Juans and going over 13,000 feet regularly guiding backpacking and peak ascents and doing personal climbing and hiking.
I've always claimed that us mountain folks only keep going cause we have selective memories… now I can blame the altitude!Oct 2, 2007 at 9:03 pm #1404373
Like the previous posters I also have not noticed any change in my own mental capabilities, nor my fellow amateur mountaineers. I am reminded of the saying: "Its difficult to comprehend how insane some people can be.. especially when you are insane." HAHAHAHA.. ;)

I've been thinking about this one a little more and just now it hit me right between the eyes; What about the Sherpas, Tibetans, or the Aymara and Quechua speakers of the Andes? Those groups seem to be doing just fine, especially the Sherpas who didn't suffer colonial oppression. I've seen the Sherpas up close and from my point of view, they're a real together bunch, very impressive indeed. Wouldn't it be interesting if the authors of the seminal report for this thread did another study, this time of the above mentioned groups. I, for one, would be most interested in the results.Mar 2, 2008 at 4:44 pm #1422781

Me – I've been over 6k Meters a few times and I am often confused over which one is Obama and which is Osama (like Letterman I also tend to confuse Uma and Oprah).
