Newly discovered vessels beneath skull could link brain and immune system

Decades of textbook teaching could be overturned by discovery, which might also explain links between poor health and brain disorders such as Alzheimer's

Scientists have discovered a previously unknown link between the brain and the immune system that could help explain links between poor physical health and brain disorders including Alzheimer's and depression.

The discovery of vessels, nestled just beneath the skull, overturns decades of textbook teaching and could pave the way for new approaches to treating brain diseases. The scientists behind the discovery described their surprise at having uncovered a major anatomical structure that until now had been entirely overlooked.
