High-Flying Pilots at Increased Risk of Brain Lesions

A new study suggests that pilots who fly at high altitudes may be at an increased risk for brain lesions. For the study, 102 U-2 United States Air Force pilots and 91 non-pilots between the ages of 26 and 50 underwent MRI brain scans. The study found that pilots had nearly four times the volume and three times the number of brain lesions as non-pilots. Symptoms affecting the brain that sometimes accompany decompression sickness include slowed thought processes, confusion, unresponsiveness and permanent memory loss. The research also found that while the lesions in non-pilots were mainly found in the frontal white matter, as occurs in normal aging, lesions in the pilots were evenly distributed throughout the brain.
