A stroke occurs when blood supply to part of the brain is suddenly interrupted or when a blood vessel in the brain bursts, spilling blood into the spaces surrounding brain cells. Likewise it is said that a person suffering a loss of blood flow to the heart has a heart attack, can say that a person with a loss of blood flow to the brain or sudden bleeding in the brain has a “brain attack” or suffer a stroke.

Brain cells die when they no longer receive oxygen and nutrients from the blood or when damaged by sudden bleeding in the brain and around it. Ischemia is the term used to describe the loss of oxygen and nutrients to brain cells when there is adequate blood flow. Ischemia ultimately leads to infarction, the death of brain cells that are eventually replaced by a fluid-filled cavity in the injured brain.

When stopping the flow of blood to the brain, some brain cells die immediately, while others remain subject to risk of death. These damaged cells make up the ischemic penumbra and can remain in a state of risk for several hours. With timely treatment, these cells can be saved. The ischemic penumbra is discussed further in the Appendix.

* The term in English to describe the stroke is “stroke”. In Spanish, many people commonly use the terms “stroke” or “stroke”.

Even when a stroke happens in the recesses of the brain, the symptoms of it are easy to detect. These include the following: sudden numbness or weakness, especially on one side of the body, sudden confusion or trouble speaking or understanding, sudden vision problems in one or both eyes Sudden trouble walking, dizziness or loss of balance or coordination, or sudden severe headache with no known cause.

All the symptoms of stroke appear suddenly and often more than one symptom at a time. Therefore, the stroke can usually be distinguished from other causes of dizziness or headaches. These symptoms may indicate the occurrence of a stroke and needed immediate medical attention.

There are two forms of stroke: ischemic stroke – when there is a blockage of a blood vessel that supplies blood to the brain, and hemorrhagic stroke – when ensangramiento occurs in the brain and around it. The following sections describe these forms of stroke detail.
