The aged vasculature is diminished in its ability to deliver blood to tissues via a range of different mechanisms and their consequences. Capillary density is lost, and the heart weakens, for example. This affects the ability to supply nutrients and oxygen to energy hungry tissues such as the brain, and this in turn affects function. The balance of supply and demand in the brain is not a steady state situation, however. It is complex, just like everything else in the body. Researchers here find a way to measure the degree to which this dynamic, complex balance becomes disrupted with age, thereby contributing to dysfunction.

A healthy brain requires sufficient supplies of glucose and o…
