Risk of Spaceflight Associated Neuro-ocular Syndrome

Exposure to altered gravity can cause ocular and brain structural changes to develop during spaceflight; these changes could lead to vision alterations, cognitive effects, or other deleterious health effects. SANS is a syndrome unique to humans that fly in space, and there is no terrestrial disease equivalent. Brain structural changes appear small but seem to indicate that over half of crewmembers experience one or more symptoms of SANS. Determining intracranial pressure during spaceflight could improve our understanding of SANS mechanisms and improve our ability to target countermeasures for determining risk for future missions.

I am the owner of Cerebral-overload.com and the Verizon Wireless Reviewer for Techburgh.com. My love of gadgets came from his lack of a Nintendo Game Boy when he was a child . I vowed from that day on to get his hands on as many tech products as possible. My approach to a review is to make it informative for the technofile while still making it understandable to everyone. Ben is a new voice in the tech industry and is looking to make a mark wherever he goes. When not reviewing products, I is also a 911 Telecommunicator just outside of Pittsburgh PA.
