The researchers of the Miami University and Columbia University defines that healthy brains associates with healthy heart by using the American Heart Association ‘life simple seven’ of cardiovascular health which include  tobacco avoidance, ideal levels of weight, physical activity, healthy diet, blood pressure, cholesterol and glucose.

The study lead author of University of Miami Hannah Gardener stated “Achieving the health metrics of Life's Simple 7 is associated with a reduced risk of strokes and heart attacks, even among the elderly."

In the research 1033 participants were tested for memory, thinking, and brain processing speed published in general heart association of America.

The researchers defines “Brain processing speed measures how quickly a person is able to perform tasks that require focused attention. Approximately six years later, 722 participants repeated the cognitive testing, which allowed researchers to measure performance over time”.
