A medicated nasal spray could reportedly reach nearly all regions of the brain within just six hours.

It is increasingly emerging that tiny particles called extracellular vesicles may aid the regeneration of brain cells, while reducing inflammation.

The scientists hope a nasal spray could be given to someone at high risk of lasting damage, like an athlete after a concussion, adding the vesicles appear to reach nearly all regions of the brain within just six hours.Stem cells are basic cells that can change into a more specialised form of cell. After isolating the vesicles under a microscope, the Texas scientists found they can carry proteins and microRNAs that help regenerate brain cells in the hippocampus, the learning and memory centre of the brain.

While further research is required, there “likely won’t be any side effects” with this sort of treatment.
