TL;DR
Breathing in hydrogen gas can significantly reduce brain damage and improve mental and motor functions in newborn rats that have suffered a type of brain hemorrhage common in very premature babies.
Key Finding
Hydrogen gas inhalation significantly reduced mental retardation and cerebral palsy outcomes in newborn rats after brain hemorrhage and normalized brain atrophy and related organ damage.
Summary
Researchers studied whether hydrogen gas could help protect the brains of newborn rats that had suffered a specific type of brain bleeding called germinal matrix hemorrhage. They found that rats treated with hydrogen gas showed better cognitive and movement abilities several weeks after the injury, and also had less brain shrinkage and organ damage compared to untreated rats.
Practical Takeaway
This is an early-stage animal study suggesting hydrogen gas may have neuroprotective properties for brain injuries in newborns. However, this research was conducted only in rats, and much more work—including human clinical trials—would be needed before any therapeutic application in premature infants could be considered. The findings are not yet applicable to human treatment decisions.
Abstract (excerpt)
Germinal matrix hemorrhage (GMH) is a neurological disease of very low birth weight premature infants leading to post-hemorrhagic hydrocephalus, cerebral palsy, and mental retardation. Hydrogen (H2) is a potent antioxidant shown to selectively reverse cytotoxic oxygen-radical injury in the brain…
