High Altitudes Put Pilots at Risk


By Molly Clifton

Pilots who fly at high altitudes may be at risk of brain lesions.

That's according to a new study that looked at MRI brain scans of more than 100 U.S. air force pilots.

The study in the journal "Neurology" found the pilots had three times the number of brain lesions as people who don't fly.

The lesions, caused by what's known as decompression sickness, can cause memory loss, and confusion.
