PATHOLOGY

Detailed explanation-1: -It is a sudden interruption of continuous blood flow to the brain and a medical emergency. A stroke occurs when a blood vessel in the brain becomes blocked or narrowed, or when a blood vessel bursts and spills blood into the brain. Just like a heart attack, a stroke requires immediate medical attention.

Detailed explanation-2: -Heart disease and stroke are part of a group of cardiovascular diseases. These diseases affect your heart and blood vessels. Stroke is a condition in which the brain can’t get blood flow. This happens because one or more blood vessels leading to the brain is blocked or bursts.

Detailed explanation-3: -A stroke, also known as transient ischemic attack or cerebrovascular accident, happens when blood flow to the brain is blocked. This prevents the brain from getting oxygen and nutrients from the blood. Without oxygen and nutrients, brain cells begin to die within minutes.

Detailed explanation-4: -There are two main causes of stroke: a blocked artery (ischemic stroke) or leaking or bursting of a blood vessel (hemorrhagic stroke). Some people may have only a temporary disruption of blood flow to the brain, known as a transient ischemic attack (TIA), that doesn’t cause lasting symptoms.
