Space flights change the shape of the brain: study reveals lasting effects

According to TSN.ua: A study published in the Proceedings of the National Academy of Sciences showed that long-duration space missions lead to physical changes in the shape and position of the brain within the skull that can persist even for half a year after returning to Earth. Analysis of MRI data from 26 astronauts, taken before and after flights, revealed that the changes are directionally dependent on the duration of the mission, with the most significant deformations observed in those who spent about a year in space.

Impact of Long Durations Flights on the Brain

As part of the study, a comparison was also made with 24 civilian volunteers who were in conditions of prolonged bed rest with the head tilted downward. Even two-week flights leave a noticeable mark on brain structure. Non-linear lateral deformations were recorded, differing in the upper and lower parts of the brain. Most indicators return to normal within six months after landing; however, certain structural changes persist for longer.

Rachel Seidler, one of the study's authors, noted: 'Understanding these processes is critically important for the safety of future journeys, particularly to Mars'.

These results highlight the importance of further research in this field, as they may impact astronaut training and strategies for future space missions.

These findings could have significant implications for planning future space expeditions, particularly missions to Mars, where flight duration may reach several years. Understanding the impact of space conditions on astronaut health will allow for the development of effective training and adaptation methods, which, in turn, will contribute to the safety and success of future deep space missions.
