POPSWhat Britney Spears Can Reveal About Alzheimer's
More: When volunteers saw names such as Britney Spears, George Clooney, and Marilyn Monroe, those who were at the highest risk of developing Alzheimer's - those with both the genetic makeup and a family history - showed high levels of activity in the hippocampus, posterior cingulate and regions of the frontal cortex, all areas involved in memory. The control group showed the opposite pattern. Their brains became more excited when they saw unfamiliar names, which included Irma Jacoby, Joyce O'Neil and Virginia Warfield. That could mean that the at-risk people were working harder to recognize the well-known celebrities, compensating for already damaged or destroyed neurons that were no longer functioning, while the control group had to struggle only when trying to place the names of noncelebrities, recruiting more nerve cells and connections, racking their memory banks and recall centers. Other signs of Alzheimer's were not present yet allowing for earlier detection.
