Two Types of Stroke

Types of Stroke

Every year, 700,000 Americans suffer from stroke, 160,000 of them are unlucky, as they die from stroke-related reasons.

Stroke is one of the most devastating attacks in the body; it is ranked 3rd leading in the health conditions that causes death in America. Before we dig deeper into this medical condition, it will be good if we start defining the condition first.

Stroke basically is a brain attack. It happens when there’s not enough blood circulation that reaches the brain. Blood carries and brings oxygen and nutrients to the cells in our body parts and also to brain cells.

When there’s a blockage along the blood flow, there will be little or even not enough blood that gets into the cells. And in the case of the brain, not enough blood can result the cells to die.

Types of Stroke

There are two types of stroke that has been categorized to determine the severity of the attack. These are caused by:

1) blockage on the blood flow

2) caused by bleeding

Blockage of blood flow is the most common type of stroke. This usually happens when there’s a blockage in the blood vessels along the neck and in the brain. This kind of condition is called ischemic, and is responsible for nearly 80% of the attacks.

The obstruction in the major artery, which is the artery in the neck that carries oxygen-rich blood from the heart to the brain is caused by atherosclerosis, a kind of fatty acid that deposits and accumulate on the inside walls of the artery. As this fatty acid deposits and grows, it narrows the space in which the blood travels.

Atherosclerosis is not the primary cause for the attack, but it is one of the many factors that set-sup the condition. There are 3 risks that lead to development of obstructions along the blood flow:

  1. Thrombosis or the clot formation along the blood vessels. Clot forms because of the atherosclerosis deposits along the arteries. The blockage confuses blood, leading blood to make a clotting, just like their response to the wound. The clotting develops giving little space for the blood to travel to the brain.
  2. Embolism or the progress of a clot or clots from a specific part of the body like the heart chambers to the vessels near the brain and the neck. The clot typically travels through the blood stream and get trapped on some vessels, usually at those with atherosclerosis formations.
  3. Stenosis or the narrowing of the arteries along the brain.

Bleeding on the other hand is called the hemorrhagic stroke. This is holds the remaining 20% of the victims of this condition. This is typically caused by severe bleeding into the brain and/or along the spaces around the brain.

Hemorrhagic attacks usually happens when a blood vessel of artery within or along the brain break and tears, causing the blood to flow out to the tissues around.

The blood that had escaped from the arteries will then compress and tweak near blood vessels causing a blockage on the flow of blood, leading surrounding tissues deprived from oxygen-rich blood. Symptoms for this kind of stoke may be more severe and sudden, making it more life-threatening than ischemic attack.

It is important to determine the kind of health condition that results to stroke attack to know what kind of medication and treatment is necessary.
