A stroke occurs when there is a sudden interruption in the blood vessel that carries oxygen and nutrients. These interruptions can be either by a clot or ruptures. In case of such disruption, blood and oxygen supply stops in the part of the brain, causing the brain cells to die.

In the United States of America, stroke has become the leading cause of disabilities and the fifth most significant cause of death. 

Have a look at the following statistics:

  • 1 in every 20 deaths in America is due to stroke, i.e., approximately 140,000 individuals.
  • Every 440 seconds, someone gets a stroke, and every 4 minutes, someone is dying out of stroke in America.
  • Over 795000 individuals have a stroke in America, as per an annual survey. Out of which, approximately 610000 are new strokes.
  • About 1 in every four individuals are the people with previous stroke records.
  • About 87% of the strokes individuals experience are ischemic strokes.
  • People spend approximately $34 billion every year on strokes. This total expense covers the cost of medicines, treatments, and the days of work people miss due to the disease.

Warning Signs Of Stroke
If you are suspicious that someone in your surroundings could have a stroke, you need to act fast. F.A.S.T will help you recognize the warning signs of a stroke.

  • Arm Weakness: You need to check if one arm of the person is drifting downwards. Ask him to lift his arms and enquire.

Types Of Stroke
Strokes are of three main types:

  • Ischemic Stroke
  • Hemorrhagic Stroke
  • Transient Ischemic Attacks
  • Here’s a brief description of each of them:

Ischemic Stroke

When arteries to your brain get blocked or narrowed, ischemic strokes occur. It results in decreased blood flow in the concerned part of the brain. Researchers have discovered that almost 80% of strokes are ischemic strokes.  

Ischemic strokes further classified into two categories:

  • Thrombotic Stroke: In this type, the artery carrying blood and oxygen to a part of the brain gets blocked. As a result, blood stops flowing to the concerned part of the brain.  The reason for blocking arteries is the formation of a thrombus(blood clot) in it. The thrombus is developed by a rugged accumulation of cholesterol and similar substances. 
  • Embolic Stroke: Brain usually depends on other arteries to bring blood from the lungs and heart. If rupture happens in any of these arteries, the stroke occurs. 

Hemorrhagic Stroke

About 20% of strokes are hemorrhagic strokes. It happens when arteries in the brain get bursts up, or some leaks occur in the brain. It causes spillage of blood in the brain and even in the surfaces in the close vicinity of the brain.

Transient Ischemic Attacks

It is called a mini-stroke and usually is a warning to the impending stroke. It lasts only for a few minutes and causes no permanent damage. When you have TIAs, ensure to take preventive measures. 

According to a survey conducted by the Centers for Disease Control and Prevention, one-third of TIA victims experiences a severe stroke in the year and that too if they haven’t received proper treatment. Approximately 10-15% of people have a stroke within three months of getting a Transient Ischemic Attack.

Risk Factors For Stroke

  • Weakness

Tests For Stroke Diagnosis
Blood Tests: The doctor does the blood test to figure out the expeditiousness of the blood clot and the level of various substances in the blood.

MRI[Magnetic Resonance Imaging] and CT[Computed Tomography] scan: MRI is done to check if any of the brain tissue or brain cells are damaged. CT scan will help detect strokes, tumors, hemorrhages, and further conditions in the brain. 

ECG: Electrocardiogram or ECG is done to detect if the stroke is the result of heart-related conditions.

Prevention Of Stroke

Lower blood pressure

High blood pressure is one of the most common risk factors that can increase your chances of getting a stroke several times. Try to keep your blood pressure below 135/85. You can do this by reducing your salt intake, avoiding high-cholesterol foods, and incorporating fresh fruits and vegetables in your diet.
