Stroke
A stroke, or cerebrovascular accident (CVA), occurs when the blood supply to part of the brain is interrupted or reduced, leading to brain cell damage. This interruption can be due to either a blockage or a rupture in the blood vessels supplying the brain. Understanding and addressing stroke risk factors, recognizing symptoms early, and seeking prompt medical attention are essential for improving stroke outcomes and reducing long-term complications.
Types of Stroke
- Ischemic Stroke : Caused by a blockage in a blood vessel supplying the brain. Occurs when a blood clot (thrombus) forms in one of the arteries supplying blood to the brain.
- Hemorrhagic Stroke : Caused by a rupture in a blood vessel in the brain, leading to bleeding (hemorrhage). Bleeding occurs in the space between the brain and the tissues covering it.
- Transient Ischemic Attack : Often called a "mini-stroke," a TIA is caused by a temporary blockage of blood flow to the brain. Although the symptoms are similar to those of a stroke, they are temporary and usually resolve within a few minutes to hours. However, a TIA is a warning sign of a potential future stroke.
