Brain & Neurology

Abstract

The brain, neurological and vestibular systems were the subject of this chapter. Pressure on the brain and astronaut headaches were documented, along with difficulty in making estimates and judgment. Cognitive impairment was correlated to the space environment, and Alzheimer’s Disease-like symptoms were noted. A brain/mental health monitor was described. Space-induced neurological disorders were discussed and neurodegeneration and neurological consequences of the space environment were considered. The effect on balance and orientation of the space environment was documented. The vestibular system was discussed and astronaut disorientation was documented. The consequences of the space environment on the vestibular system were discussed.
