Scientists Develop Nasal Spray That May Help Reverse Signs of Brain Aging

According to the research team, this approach allows treatment to reach the brain more directly and efficiently.

What Happens Inside the Aging Brain?

As we age, chronic low-level inflammation can slowly build up inside the brain.

Scientists sometimes refer to this process as “neuroinflammaging.”

Over time, this inflammation has been linked to:

  • Memory problems
  • Slower thinking
  • Reduced cognitive performance
  • Increased risk of dementia
  • Alzheimer’s disease

At the same time, the brain’s energy-producing structures, called mitochondria, become less efficient.
