It is important to know the symptoms of a stroke. Warning signs include sudden loss of speech, sudden loss of vision, weakness, dizziness, or a severe headache, among others. A stroke is a medical emergency, and it is critical to call 9-1-1 and get treatment immediately.
A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked (blood clot) or ruptures. When that happens, parts of the brain cannot get oxygen, and the brain and brain cells begin to die. Quick action is essential to reducing brain damage and other grave complications.
There are two categories of stroke, an ischemic stroke, where an artery or blood vessel is blocked by a blood clot. A Hemorrhagic Stroke is when a blood vessel or artery bursts and leaks into the brain. Approximately 80% of strokes are ischemic and 20% hemorrhagic.
Smoking, obesity, diabetes, and high blood pressure all can considerably increase your risk of stroke.
If you or someone you know is having a stroke it is vital to seek help immediately.
