Researchers are exploring the potential of xenon gas, a rare and unreactive element in the Earth's atmosphere, to revolutionize both high-altitude climbing and the treatment of Alzheimer's disease. British mountaineer Garth Miller is currently testing xenon's purported ability to enhance blood oxygen capacity during his ascent of Mount Everest. Meanwhile, scientists at Mass General Brigham and Washington University School of Medicine in St. Louis are investigating xenon's potential therapeutic effects on Alzheimer's disease, a leading cause of dementia worldwide.
Xenon gas, which comprises a mere 0.086 parts per million of the air we breathe, has shown promise in increasing the oxygen-carrying capacity of blood. This property is being put to the test by Garth Miller as he climbs the world's tallest peak. If successful, this could provide climbers with a significant advantage in extreme altitudes where oxygen levels are perilously low.
Beyond the realm of mountaineering, researchers are examining xenon's potential to treat Alzheimer's disease. A study funded by the Alzheimer's Association found that inhaling air with 30% xenon gas for 40 minutes yielded beneficial effects in mice models of Alzheimer's. Dr. Anton Porsteinsson remarked on these findings:
“The results are intriguing. Importantly, we know a lot about xenon gas and its impact on humans from anesthesia in terms of safety and tolerability. It is quite expensive and there would be a challenge understanding how to deliver it to a large patient group and avoid anesthetic events.” — Anton Porsteinsson, MD
Alzheimer's disease remains an ever-growing concern, affecting millions and challenging researchers to find treatments capable of crossing the blood-brain barrier. The potential for xenon gas as a treatment option is currently under scrutiny in preparation for a clinical trial led by Dr. Howard Weiner, co-director of the Ann Romney Center for Neurologic Diseases at Brigham and Women's Hospital (BWH). Dr. Weiner expressed optimism about the trial:
“If the clinical trial goes well, the opportunities for the use of Xenon gas are great. It could open the door to new treatments for helping patients with neurologic diseases.” — Howard Weiner, MD
The study's results have sparked interest in xenon as a novel therapeutic approach. Dr. Heather M. Snyder from the Alzheimer's Association emphasized the importance of further research:
“This newly published study represents an interesting idea for possible future treatment of Alzheimer’s and other neurodegenerative diseases, and it deserves further investigation — including confirmation in other model systems and initial safety testing in people.” — Heather M., Snyder, PhD
While mouse models provide initial insights, they often fall short in predicting human outcomes. Therefore, further research is necessary to confirm xenon's effectiveness and safety in humans. An essential aspect of this research involves understanding how immune cell interactions may affect brain changes associated with Alzheimer's.
“Understanding how the immune cells interact with one another and how this cross-talk may impact brain changes observed in people with Alzheimer’s, is a critical part of this work.” — Heather M., Snyder, PhD
