What happens when the brain doesn t get enough blood?

When the brain doesn't get enough blood, a condition known as cerebral ischemia occurs. This can lead to an Ischemic Stroke, which happens when part of the brain is injured because it isn't getting enough blood. The brain needs a constant supply of blood, which carries oxygen and other nutrients necessary for the survival of brain cells. If the blood supply is interrupted or reduced, brain cells can become damaged or die, leading to potentially severe and lasting effects. The severity and symptoms of an ischemic stroke depend on the extent of the blood flow reduction and the specific area of the brain affected. Symptoms can range from mild to severe and may include sudden numbness or weakness in the face, arm, or leg (especially on one side of the body), confusion, trouble speaking or understanding speech, difficulty seeing in one or both eyes, difficulty walking, dizziness, or severe headache with no known cause. Immediate medical attention is crucial for anyone experiencing stroke symptoms, as treatment options are most effective when administered quickly. Treatment typically involves restoring blood flow to the affected area of the brain, often through the use of clot-busting drugs or surgical procedures.
