A stroke occurs suddenly, without warning, leaving no time to prepare. In a matter of seconds, it can change the course of your life. It is one of the leading causes of death after age 75, and yet many people are unaware that numerous risk factors for stroke are within their control.
The scariest part? A stroke rarely gives you a second chance. Once it happens, the damage is often irreversible. But here’s what might surprise you: up to 80% of strokes are preventable. This means your everyday choices, right now, can determine whether you remain independent or face a life-changing health crisis.
A stroke occurs when blood flow to the brain is suddenly blocked or when a blood vessel in the brain ruptures. Without oxygen, brain cells begin to die within minutes. Some strokes cause mild symptoms, such as temporary confusion or weakness, while others can lead to paralysis, loss of speech, or complete dependence.
High blood pressure is one of the most common and dangerous causes of stroke. Over time, the extra pressure damages the arteries, increasing the risk of them bursting or becoming blocked. Another cause is irregular heart rhythms, such as atrial fibrillation. Many older people have this condition without knowing it.
A crucial, but often overlooked, warning sign of a future stroke is what’s known as a mini-stroke or transient ischemic attack (TIA). These events can cause sudden confusion, blurred vision, or slurred speech. Even if these symptoms disappear quickly, they should never be ignored.
