Controlling blood pressure is one of the most straight-forward ways of preventing one form of cognitive decline.
According to Duke Medicine Health News, high blood pressure can lead to tiny strokes in the brain, a condition called vascular dementia.
These little strokes take a toll on memory, reasoning, judgment and a general decline in thought processes.
Controlling blood pressure also reduces the risk of major cardiovascular problems. So, it seems, what is good for the heart is good for the brain.
