When it comes to strokes, time is everything. Quick intervention often determines whether a person survives and how well they recover. That’s why it is so important to raise awareness about what a stroke is, the types that exist, and the subtle warning signs that may appear weeks before an actual event.
What Is a Stroke?
A stroke occurs when blood flow to the brain is interrupted, depriving it of oxygen. Without oxygen, brain cells begin to die within minutes. Strokes can have devastating consequences, ranging from long-term disability to death.
There are several types of stroke:
Ischemic stroke (most common): Caused by a blood clot or cholesterol plaque blocking an artery, also known as an embolism or thrombosis.
Hemorrhagic stroke: Less common, but often more severe. It results from a ruptured aneurysm, brain tumor, accident, or vascular disorder.
Transient Ischemic Attack (TIA): Sometimes called a “mini-stroke,” this is a temporary blockage that resolves on its own. While symptoms may disappear quickly, TIAs should never be ignored, as they are often precursors to a full stroke.
