Space travel can change astronauts’ brains for years

A new study reveals that lengthy space voyages can cause expansion of the ventricles in astronauts' brains, with the ventricles taking over three years to return to their normal size. The research examined the MRI scans of 30 astronauts and found that longer missions resulted in more significant ventricle expansion. Brain changes are associated with microgravity. The long-term impact on performance and health remains uncertain.
