Brain blood flow deficits in Alzheimer's explained

  • Blood flow deficits in the brain, seen early on in Alzheimer's, have now been linked to some capilleries being block by white blood cells.

It’s been known that decreased blood flow in the brain occurs in people with Alzheimer's, and recent studies suggest that brain blood flow deficits are one of the earliest detectable symptoms of dementia. A study has now shown why it occurs: a small percentage of capillaries, the smallest blood vessels in the brain, are blocked by white blood cells stuck to the inside of the capillaries.

Recent research has shown that capilleries are vital for monitoring and directing blood flow around the brain.
