Background It is reported that environmental factors such as hypoxia could contribute to the pathogenesis of Alzheimer’s disease (AD). Therapeutics like hyperbaric oxygen treatment which improves tissue oxygen supply and ameliorates hypoxic conditions in the brain may be a strategy for AD and amnestic mild cognitive impairment (aMCI) treatment. The present work aims to investigate the potential therapeutic effect of hyperbaric oxygen treatment in patients with AD and aMCI. Method We included 42 AD and 11 aMCI patients in this study. All participants were continuously treated with hyperbaric oxygen treatment once daily for 20 days and assessed by neuropsychiatric assessments before and at 1, 3, and 6 months after the hyperbaric oxygen treatment. We also applied fluorodeoxyglucose positron emission tomography (FDG‐PET) in some of the patients. Result Hyperbaric oxygen treatment could improve the global cognitive functions, especially visuospatial and executive functions, language and abstract thinking abilities at 1 month after treatment in AD patients and improved the memory of aMCI patients in 1, 3, and 6 months after treatment. The ADL scores were improved in 1, 3, and 6 months after treatment in AD patients. Hyperbaric oxygen treatment also ameliorated the reduced brain glucose metabolism in AD and aMCI patients. Conclusion Based on the previous studies and our recent findings, hyperbaric oxygen treatment may be a potential therapeutic and preventive strategy for AD and aMCI.
