Final answer:
A stroke, specifically option B, is the death of brain tissue due to an interruption in blood flow, often caused by an embolus blocking an artery in the brain. Unlike a stroke, a transient ischemic attack is a temporary interruption that doesn't cause permanent brain damage. Immediate treatment for strokes is vital for recovery. B. a stroke
Step-by-step explanation:
The death of brain tissue due to interruption in blood flow is known as B. a stroke. A stroke, also referred to as a cerebrovascular accident (CVA) or brain attack, happens when there's a blockage or rupture of arteries in the brain leading to the death of brain cells. The primary form of stroke is an ischemic stroke, where an embolus (blood clot) travels to the brain and lodges in an artery, blocking the blood flow to a part of the brain and causing brain cells to die from lack of oxygen.
Related but different is a transient ischemic attack (TIA), often called a mini-stroke, which results from a temporary interruption of blood supply and causes neurological function loss. However, this loss is not permanent as the blood flow resumes before brain cells die.
It's crucial to seek immediate medical attention for a stroke because the sooner treatment is received, such as with a clot-busting drug, the better the chances of preventing permanent brain damage.
