Nasal Spray Rejunvenates Brains
from Dr. Howard Smith Reports · host Howard G. Smith MD, AM
Vidcast: https://www.instagram.com/p/DZ1zfXYsAn2/Two sprays of a nasal spray developed by Texas A&M University neuroscientists reverses some signs of brain aging. And the effect lasts for months. Their studies appear in the Journal of Extracellular Vesicles.The nasal spray contains biological particles called extracellular vesicles which transport microRNAs. In mouse studies, this treatment reduces chronic brain inflammation, restores the mitochondrial energy sources inside brain cells, and improves memory and recognition abilities. The therapy appears to reactivate the brain’s natural repair systems and helps neurons recover their ability to process and store information.This brain inflammation and declining cellular energy are linked to memory loss, brain fog, dementia, and Alzheimer’s disease. If future human studies confirm these findings, a simple nasal spray could someday become a noninvasive way to help maintain cognitive health as people age.On the other hand, this therapy has not yet been tested in humans. When it is, controlled clinical studies are needed before it could become approved and acceptable therapy.
