Study: Long-Term Space Flight Could Up Brain Volume

STUDY: LONG-TERM SPACEFLIGHT COULD PERMANENTLY INCREASE ASTRONAUT BRAIN VOLUME, CAUSE PITUITARY PROBLEMS

(CNN) – According to a new study, long-term space flight could permanently increase an astronaut’s brain volume.

And that’s not a good thing.

The findings of the study published on Tuesday in the journal radiology also indicate that the effects can include a deformation of the pituitary gland.

The so-called “master” gland is responsible for the functions of multiple other glands in the human body.

The study’s lead author said micro-gravity causes blood to redistribute toward the head instead of pooling toward lower extremities.

This creates more pressure on the head.

11 astronauts were a part of the study.

The researchers found that increases in their brain and cerebrospinal fluid volume remained a year after space flight.

They believe this means the volume increase is permanent.

Efforts are underway to find measures to counteract the fluid shift and head pressure.
