How a "Leaky Brain" Raises Your Risk of DementiaIt has been a hundred years since a Nobel Prize winner discovered the thin barrier that surrounds and protects the brain. Since then, we’ve learned this mesh of tightly joined cells, called the blood-brain barrier, is highly selective in a healthy person. It allows the transport of compounds back and forth through an intricate transport system while keeping out most everything else in the blood stream that can damage the brain. This includes heavy metals, toxic proteins, pathogens, and red and white blood cells.
Accelerated aging + Inflammation = Leaky BrainNow, scientists have discovered that brain degeneration weakens the blood-brain barrier and causes it to “spring leaks.” This is especially true in the hippocampus, the area of the brain associated with learning and memory. This discovery adds to the growing evidence that diseases of aging such as dementia and Alzheimer’s are sometimes linked to what functional medicine practitioners call a “leaky brain.”
