Cardiovascular Risk Factors Promote Brain Hypoperfusion Leading to Cognitive Decline and Dementia
de la Torre Jack C.
Cardiovascular Psychiatry and Neurology 2012 (2012), Article ID 367516, 15 pages
It has been known since the Ebers papyrus in 1552 BC, and probably even before then, that the brain and heart are intimately connected. The ancient Greeks and Aristotle in particular believed that the function of the brain was to "cool" the blood while the heart was the source of memory. This belief was consolidated by religious and scientific dogma for centuries. It took the most significant...
