We analyzed the effects of 4-week H2 inhalation on cognitive performance in women aged 65 and above. The participants (n = 13) were community-dwelling older women (age 68.0 ± 3.0 years; weight 66.9 ± 10.3 kg; height 161.1 ± 5.8 cm) who volunteered to participate in this open-label pilot trial (ClinicalTrials.gov, NCT02830854). The participants received H2 by inhalation for 15 min once per day for 4 weeks. The cognitive function was assessed using the Mini Mental State Exam (MMSE) and Alzheimer disease assessment scale cognitive subscale (ADAS-Cog) at baseline and at follow up. H2 intervention significantly increased total MMSE scores (for 14.2% on average; p < 0.01), thereby improving cognitive function from mild dementia at baseline (a score of 25.6 out of 30) to normal cognition at follow up (above a cut score of 27). In addition, ADAS-Cog scores were significantly improved by H2 inhalation, with better performance for word recall test (p < 0.01), and improved word recognition (p = 0.01) at post-administration, respectively. This pilot trial seems to corroborate previous animal studies, suggesting that gaseous H2 might be considered as a beneficial agent for age-related cognitive health.
Objective: Sepsis-associated encephalopathy (SAE) is characterized by diffuse cerebral and central nervous system (CNS) dysfunction. Microglia play a vital role in protecting the brain from neuronal damage, which is closely related to inflammatory ...
The development and maintenance of morphine tolerance showed association with neuroinflammation and dysfunction of central glutamatergic system (such as nitration of glutamate transporter). Recent evidence indicated that hydrogen could reduce the ...
Background and purpose: Poor-grade subarachnoid hemorrhage still has a poor prognosis. This randomized controlled clinical trial evaluated intracisternal magnesium sulfate infusion combined with intravenous hydrogen therapy in patients with ...
Hydrogen inhalation therapy has been proven to be safe and effective in disease treatment in multiple clinical reports, but the gas flow rates used in different studies vary greatly. Since there is no upper limit for the safe concentration of ...

In this study, hydrogen generation powder samples were prepared using zinc carbonate as a precursor, at a temperature varying from 400 to 700 °C in H2 atmosphere, and were characterized in terms of antioxidant activity. The concentration of ...
