Long-term exposure to microgravity during space travel causes astronauts to develop a rare neurological syndrome in which the brain shifts upward crowding the cranium.
Dr. Donna Roberts, lead author of the study published this week in the New England Journal of Medicine, said research has shown roughly 40 percent of astronauts return from space missions and report neurological issues. The top of the brain that is affected by the syndrome controls sight, and astronauts often report symptoms such as blurry vision, swelled optic disks, migraines and increased head pressure. NASA calls the constellation of symptoms visual impairment and intracranial pressure (VIIP) syndrome.
Normally, the brain floats in a bath of cerebrospinal fluid, partly a function of anatomy but, also, as the study suggests, a result of gravity... More ... (Newsweek - 2 Nov 2017)
