🧠 Brain Ischemia: When the Blood Stops Flowing
Brain Ischemia (also called Cerebral Ischemia) is a serious condition that happens when the blood flow to a part of your brain is reduced or completely blocked.
What Is It?
Your brain needs a constant supply of oxygen and nutrients carried by blood to function. Ischemia is essentially a blood-flow crisis.
When the supply is cut off, brain cells are quickly starved of oxygen. If this lasts for more than a few minutes, the tissue starts to die, which is what we call an Ischemic Stroke.
It's often caused by a blood clot that travels up to the brain or by narrowed arteries (like from plaque buildup) blocking the path.
