Effect of Hydrogen Water Drinking on Dementia Patient through Mechanism of Oxidative Stress and Immune Redox Balance

Abstract:

Hydrogen water (HW) which is produced by electrolysis of water has characteristics of extremely low oxidation-reduction potential (ORP) value and high dissolved hydrogen (DH). It has been proved to have various beneficial effects including antioxidant and anti-inflammatory effects; however, HW effect on dementia that is associated with cognitive impairment and memory loss, is poorly documented. In the present study, we investigated the drinking effects of hydrogen water on dementia patient for prevention through oxidative stress and immuno redox mechanism. Dementia patients were administered with HW and purified water (PW) for 6 months. Further, we evaluated hydrogen water effect on the cognitive impairment by checking the serum concentration of Alzheimer's disease (AD) biomarkers [Amyloid β (Aβ) 40, Aβ 42 and tau], inflammatory cytokines such as IL-1β, IL-6, IL-13, TNF-α, IL-10 and IL-4, Th1/Th2 cytokines such as IL-2, IFN-γ, IL-12p70 and IL-5, reactive oxygen species (ROS), and nitric oxide (NO) levels. We found that HW treatment significantly decreased the serum level of Aβ 40 after 6 mon of treatment. In parallel, inflammatory cytokines were significantly inhibited in experimental group compared to control group. In line, Th1/Th2 cytokines were significantly decreased in HW than PW group. Furthermore, oxidative stress markers such as ROS and nitric oxide level were decreased in HW treated group than PW control group. Overall our clinical results strongly recommended that drinking hydrogen water might be a promising preventative approach for age-related neurodegenerative disease like dementia and have an enormous impact on future healthcare for the elderly patients. This might be the first note on the clinical application of drinking HW on the serum of dementia patients.
