Transcranial magnetic stimulation as a countermeasure for behavioral and neuropsychological risks of long-duration and deep-space missions

Abstract

Long-duration spaceflight missions are on the rise. However, recent literature suggests that prolonged and deep-space exposure is likely to introduce increased risks for brain health and consequent detriments to performance and well-being. Given up-to-date evidence, we argue that transcranial magnetic stimulation (TMS) is a promising solution for mitigating behavioral and neurocognitive risks associated with long-duration and deep-space missions. We provide support from recent Earth-based applications of TMS and review several advantages it holds over current treatment approaches. Lastly, we highlight some of the needs in the process of applying such technology to the spaceflight environment.
