Scientific American om bergsklättring

Ur Scientific American:

All eight Aconcagua climbers showed cortical atrophy on MRI scans. Seven showed enlarged VR spaces, and four showed numerous subcortical lesions. Some needed no scan to tell them their brains had been injured. One climber suffered aphasia (problems with speech), from which he recovered six months later. Two complained of transient memory loss after returning, and three others struggled with bradypsychia (slowed mental function).

The body is remarkably resilient: Does the brain recover from these mountaineering wounds? To answer this question, the researchers reexamined the same climbers three years after the expedition, with no other high-altitude climbing intervening. In all cases, the damage was still apparent on the second set of scans.

Nu förväntar jag mig att se Martin Ingvar stå på barrikaderna för ett förbud mot bergsklättring.
