The Effects of Altitude on Brain Activity
Chris Imray discusses the effect of altitude on brain activity. He explores the history behind his research, as well as the concept of high altitude cerebral pathologies.
Chris introduces a new idea – the concept of ‘extreme altitude cerebral dysfunction’.
Chris started climbing whilst at school and has continued to travel all over the world to indulge this passion. His interest in altitude research began when working with the Birmingham Medical Research Expeditionary Society. More recently he’s been involved with the UCL team at CASE.
Having been one of the medical officers taking part in the 2006 Xtreme Cho Oyu expedition to Tibet, Chris went on in 2007 to be the Deputy Climbing Leader of the Caudwell Xtreme Everest Expedition. Following this, he summited both Cho Oyu (8201m) and Everest (8848m), and has the dubious distinction of having the second-lowest arterial gases ever recorded in an adult (at 8,400m)!
Chris has a Diploma in Mountain Medicine and his mountain medical interests include frostbite, non-freezing cold injuries, extreme altitude physiology and the brain at high altitude. Keen to share their knowledge and expertise, Chris, along with Dr Paul Richards and Dr Dave Hillebrandt, established the UK internet-based frostbite service. As a result, they have helped hundreds of climbers tackle frostbite issues and concerns.
