Objective: Review major neurological afflictions in astronauts. Methods: Research into bibliographic reviews at PubMed, using the descriptors “astronauts” and “neurological disorders” Results: Several neurological alterations, such as ataxy, intracranial hypertension (ICH), neuromuscular disorders, ocular disturbances and changes in cognitive functions were assigned to a microgravity environment. Astronauts returning from space presented ICH; being the main pathophysiology hypothesis referred to a change in the liquor dynamics as a result of venous drainage obstruction and hematoencephalic barrier. Also, gravity doesn’t act on the neurovestibular system during space flights. This phenomenon can lead to Space Motion Sickness, situation in which astronauts report balance, coordination and sight disturbances, as well as movement illusions. A subset of...
