High altitude related exposure results in decreased oxygen supply to brain. Brain being most sensitive to hypobaric hypoxia, gets adversely affected. Our study investigates the changes in metabolic profiles of rat brains hippocampus region due to acute hypobaric hypoxia stress and recovery using invivo magnetic resonance spectroscopy. Results showed significant decrease in levels of glutamate,myoinositol,NAA,creatine but increase in choline indicating hypobaric hypoxia induced damage in hippocampus of rat brain. These studies can be helpful in detecting early biomarkers for high altitude stress injuries in humans which can further be used for risk assessment & early diagnosis.
