Alzheimer's Disease May Be Danger For Astronauts Exposed To Space Radiation, Mouse Study Suggests




Radiation in space might harm the brains of astronauts in deep space by accelerating the development of Alzheimer's disease, a new study on mice suggests.

The research reveals another risk that manned deep-space missions to places such as Mars or the asteroids could pose, scientists added.

"This study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer's disease," study author Kerry O'Banion, a neuroscientist at the University of Rochester Medical Center, said in a statement.
