Stroke, the most common cause of adult disability, has the power to transform lives permanently. It impacts the victims and their families by robbing them of their independence. Stroke is the third leading cause of adult deaths in the United States.

A stroke, also referred to as "brain attack”, results when the blood supply to the brain is obstructed. A decreased blood supply is synonymous with low levels of oxygen which leads to the death of brain cells and, finally, stroke.

Types

Stroke can be largely categorized into two types:-

• Ischemic strokes are those that result due to a blockage of blood vessel in the neck or brain. 80% of strokes are ischemic. This blockage may be due to:

- The formation of a clot, denovo, (thrombosis), within a blood vessel of the brain or neck.

- The movement of a clot from another location within the body to the neck or the brain (embolism).

- Stenosis (or narrowing) of an artery inside the brain or leading to it.

• Hemorrhagic strokes are those that result from internal bleeding into the brain or into the spaces surrounding the brain.

How to handle Stroke

There are two sure ways of minimizing a person’s risk of dying from a stroke. They are:-

• Understanding the symptoms / signs and risk factors of stroke

• Controlling the risk factors

Symptoms and Signs of Stroke

If any of the following symptoms are experienced you may be at a risk for Stroke. At such time do not hesitate to seek medical help.

• Sudden numbness / weakness in the face, arm or leg, particularly on one side

• Sudden confusion

• Sudden difficulty in speaking /comprehending

• Sudden trouble in vision in either one or both eyes

• Double vision

• Sudden headache with no apparent cause

• Sudden difficulty in walking

• Dizziness, nausea, vomiting

• Loss of balance / coordination

Sometimes these signs may last for a few minutes and then disappear. These miniscule episodes are called ‘Transient Ischemic Attacks’ (TIAs), or ‘mini-strokes’. The brevity of these mini strokes should not deter a person from seeking medical help as they are indicative of a grave underlying condition.

Please listen to these signs to save your life!

Stroke Risk Factors

A risk factor is a medical condition or a behavioral trait that is observed in those whose chances of getting a disease is high.

Stroke is universal—it affects people - of all age groups, of both genders—who belong to all the races all through the world. The ethnicity of the African American makes them more prone to stroke compared to other ethnic groups, within the United States.

Stroke can even affect a fetus inside its mother’s womb.

Age is another factor which makes an individual more prone to get a stroke.

But there are other treatable risk factors for stroke that can be identified, monitored and controlled. They are:-

• Hypertension or increased blood pressure is not known as ‘silent killer’ for nothing. It is the most severe cause of stroke.
