Breathing drives CSF: Impact on spaceflight disease and hydrocephalus [Biological Sciences]

With great interest we have read the article in PNAS by Van Ombergen et al. (1) asserting that long-duration spaceflights cause persistent enlargement of brain cerebrospinal fluid (CSF) spaces in cosmonauts. Remarkably, the postflight ventricular volume changes in the lateral ventricle correlate positively with visual acuity loss—a well-known sequela of...
