A team of researchers from Boston University has determined that the healthier your heart is, the slower your brain ages. On the flip side, those with less-than-optimal heart health experience more rapid brain aging than those whose hearts have a more healthy blood flow.
The team evaluated 1,500 people for the study and found that, as the brain ages, it actually begins to shrink. When the heart is pumping blood at a healthy rate, the brain is able to keep "fit". But in people whose blood flow is restricted by poor cardiac function, their brains age roughly two years quicker on average.
Interestingly, it is not just old people with heart disease whose brains age quicker; otherwise healthy people in their 30s who have less-than-par blood flow to the heart experience more rapidly aging brains than those with healthy flow. Read more...
