Scientists say they've reversed brain aging with a simple nasal spray

Researchers at Texas A&M University have developed a nasal spray containing microscopic particles called extracellular vesicles that appears to reverse brain aging by reducing chronic inflammation and restoring cellular energy in the brain. In studies, the treatment improved memory and cognitive function after just two doses and lasted for months, with potential applications for treating dementia and Alzheimer's disease. The nasal delivery method allows the therapy to bypass the brain's protective barrier and directly target inflammatory pathways and restore mitochondrial function in brain cells.
