Nasal Spray Reverses Brain Aging

Researchers at Texas A&M University, led by Ashok Shetty>>>, Madhu Leelavathi Narayana>>>, and Maheedhar Kodali>>>, have developed an experimental nasal spray that shows promise in reversing brain aging. The therapy, which uses extracellular vesicles loaded with microRNAs, significantly reduced chronic brain inflammation, restored mitochondrial activity, and improved memory and cognitive function in early studies. Delivered intranasally, it bypasses the brain's protective barrier, offering a non-invasive treatment approach. The findings, published in the Journal of Extracellular Vesicles and supported by the United States — National Institutes of Health>>>, suggest potential future therapies for conditions like Dementia UK>>> and Alzheimer s disease. While still in early stages and not yet tested in humans, the research offers hope for healthier aging and addresses the rising global rates of neurodegenerative disorders.
