I find some articles as shown below, when astronauts go from Earth to Space, they experience Hypertension. I would like to know on how astronauts handle this change within a short period of time and protect their brains, which would directly effect their performance.
Do you have any suggestions?
Thank you very much for any suggestions :>
Dementia. Dementia is a brain disease resulting in problems with thinking, speaking, reasoning, memory, vision and movement. There are a number of causes of dementia. One cause, vascular dementia, can result from narrowing and blockage of the arteries that supply blood to the brain. It can also result from strokes caused by an interruption of blood flow to the brain. In either case,
high blood pressure may be the culprit.
http://www.mayoclinic.org/diseases-conditions/high-blood-pressure/in-depth/high-blood-pressure/art-20045868 Hypertension is a circulatory disease. Many patients with high blood pressure develop coronary artery disease or heart failure, and many die as a result. But all parts of the body depend on the circulation, and many organs suffer from the impact of untreated hypertension. One of the organs at greatest risk is the brain.
High pressure, high risk
High blood pressure is the leading cause of strokes, both symptomatic and silent. Both systolic and diastolic hypertension contribute to risk; the higher your pressure, the higher your risk. According to one Harvard study, hypertension increases a man's risk of stroke by 220%; according to another, each 10 mm Hg rise in systolic pressure boosts the risk of ischemic stroke by 28% and of hemorrhagic stroke by 38%.
