New Nasal Spray Therapy Shows Promise in Restoring Memory and Cognitive Function in Aged Brains

Researchers at Texas A&M University have developed a new nasal spray therapy using extracellular vesicles (EVs) derived from human neural stem cells. This therapy effectively reduces chronic brain inflammation in aged mice, restoring memory and cognitive functions by blocking inflammatory signaling pathways and shifting brain immune cells to a protective mode.

New nasal spray drug shows promise against age-related cognitive decline

Researchers developed a nasal spray containing extracellular vesicles to combat age-related chronic brain inflammation and cognitive decline. In trials on mice, the drug reduced inflammation and oxidative stress, improved memory, and restructured immune cells in the brain.

Hong Kong researchers develop ‘world-first’ nasal spray for rapid stroke aid

Researchers at the University of Hong Kong (HKU) say they have developed a world-first nasal spray that delivers neurotherapeutic powder directly to the brain as first aid for ischemic stroke patients, with clinical trials expected by 2030. The treatment is intended for initial use by paramedics, before being rolled out to high-risk groups in care facilities and eventually the general public through pharmacies. It was developed by the Li Ka Shing Faculty of Medicine at HKU and the university’s...
