How Exercise Helps Protect the Brain After Heart Injury
Aerobic Exercise Activates Fibroblast Growth Factor 21 and Alleviates Cardiac Ischemia/Reperfusion-induced Neuronal Oxidative Stress and Ferroptosis in Paraventricular Nucleus

Surprising Findings
Exercise-induced neuroprotection may be mediated by FGF21 in a specific brain region (PVN) previously not strongly linked to exercise benefits.
Most research focuses on exercise boosting brain health via the hippocampus or cortex; the PVN’s role in cardiovascular control makes this a novel and unexpected target.
Practical Takeaways
Engage in regular aerobic exercise to potentially boost natural protective systems in the brain that respond to heart stress.

Exercising regularly might help protect the brain in animals with heart damage by boosting certain protective proteins and reducing harmful stress in brain cells.
In brain cells from mice, a protein called FGF21 helps protect against damage caused by lack of oxygen and sugar, and this protection seems to work through a specific cellular switch called AMPK.
When the heart doesn't get enough blood and then gets it back, it can cause harmful changes in a part of the brain that controls stress and blood pressure, leading to a specific kind of brain cell damage in animals.
When you exercise or skip meals, your body makes a special protein called FGF-21 that helps it adapt and get healthier in response to the stress of those activities.
