At its annual scientific meeting held in Adelaide, the Royal Australian and New Zealand College of Radiologists (RANZCR) highlighted brain MRI findings related to the health impact of microgravity on astronauts.
The research found that spaceflight neuro-ocular syndrome and certain neurological diseases are linked to enlarged perivascular space drainage or the brain waste clearance system called "glymphatics." These are often seen in astronauts with long exposure to microgravity in the International Space Station.
The study combined brain MRI findings from astronauts at NASA, the European Space Agency, and the Russian Space Agency. The research also discusses measures designed to support astronauts' brain health.
