WHAT IS STROKE

Stroke Effects

Stroke is the 5th leading cause of death in the US, with one person dying every 4 minutes as a result. For black people, stroke is the 3rd leading cause of death.

A stroke is caused by a blood clot or another type of blockage in a blood vessel to the brain. Oxygen in the blood is cut off to the brain and, as a result, the area of the brain supplied by that blood vessel is damaged and may die. Sometimes, when the blood supply is stopped for just a few minutes, the brain tissue is injured but recovers within a few hours or a few days. Other times, when the blood supply is stopped for a longer period,the injury is more severe, and the brain tissue doesn't recover.


Blockages of the blood supply to the brain can be caused by a blood clot or by a buildup of cholesterol in the walls of a blood vessel (Atherosclerosis). The blockages can cut off oxygen to the brain and cause a stroke or a transient ischaemic stroke (TIA). A TIA is a mini stroke that occurs when oxygen to the brain is cut off for a limited time. The blockage is usually a blood clot or a piece of cholesterol that breaks of the wall of an artery.

Symptoms of a blockage can include loss of consciousness, vision,numbness, weakness, paralysis or dizziness. If the symptoms pass within minutes to hours, the attack was probably due to a TIA and the damage won't be permanent. But it is an indication that a stroke may likely occur in the future.

Anyone who has a sudden and severe headache, stiff neck, drowsiness, fainting, or trouble with seeing, speaking, or hearing, should be seen right away by a doctor. This is an emergency.

According to World Heart Federation report:


Every year, 15 million people suffer a stroke, nearly six million die and another five million are left permanently disabled.



Globally stroke is the second leading cause of death above the age of 60 years, and the fifth leading cause of death in people aged 15 to 59 years old 


Chances of having a stroke can be reduced by:
Controlling high blood pressure,

Managing glucose levels and cholesterol

Quitting smoking, since it damages the arteries.
