A stroke occurs when the blood supply to the brain is suddenly interrupted. When the brain lacks sufficient blood flow for a long enough period of time, brain damage or even death can result. Immediate medical attention and early treatment are critical to help minimize damage to brain tissue and improve the outcome.
There are two major types of strokes: ischemic and hemorrhagic. Ischemic strokes, the most common type, occur when which a blood clot blocks the arteries leading to the brain and cuts off blood flow. A hemorrhagic stroke occurs when a blood vessel in part of the brain becomes weak and bursts open, causing blood to leak into the brain.
At the first sign of a stroke, patients should seek medical care immediately. Symptoms of a stroke vary, but typically occur suddenly and include:
Smoking is the number one risk factor for strokes, and indeed, making basic lifestyle changes like quitting smoking can significantly reduce your overall risk. These include:
Aside from lifestyle changes, managing any underlying health conditions, including hypertension and diabetes, also reduce your risk of stroke. If you are concerned about your stroke risk, talk to your cardiologist about what more you could be doing to keep your risk low.
