Acute flaccid myelitis infectious disease should be considered as a cause when patients presented with neurologic symptoms. A subsequent report described 29 cases of enterovirus D68-associated acute flaccid myelitis in Europe in 2016, noting that "these probably represent only the tip of the iceberg." AFM is diagnosed by examining a patient’s nervous system in combination with reviewing images of the spinal cord. A doctor can examine a patient’s nervous system and the places on the body where he or she has weakness, poor muscle tone, and decreased reflexes. In addition, a doctor can do magnetic resonance imaging to look at a patient’s brain
Effect of spaceflight on the human body reduce their aerobic capacity, and slow down their cardiovascular system. As the human body consists mostly of fluids, gravity tends to force them into the lower half of the body, and our bodies have many systems to balance this situation. When released from the pull of gravity, these systems continue to work, causing a general redistribution of fluids into the upper half of the body. This is the cause of the round-faced 'puffiness' seen in astronauts. Redistributing fluids around the body itself causes balance disorders, distorted vision, and a loss of taste and smell. A 2006 Space Shuttle experiment found
