What is a Stroke?

Justin Bailey

What is it?

A Stroke occurs when the supply of blood to the brain is either interrupted or reduced. When this happens, the brain does not get enough oxygen or nutrients which causes brain cells to die.

How to diagnose a stroke?

Diagnosing a stroke can be done by blood tests, physical examinations, CT scan, MRI's, etc. Strokes are the 4th leading cause of death in America, with one person dying every 4 minutes as a result.

How do strokes occur?

A person can get a stroke when they have either a blocked artery or the leaking or bursting of a blood vessel. The brain doesn’t receive the blood it needs to operate and will lead to a stroke. An individual's genetic makeup is fixed from birth. It has long been known however that genetics may contribute up to 50% of an individual's risk of developing a stroke in future. Bad diets can result in high blood pressure which can also lead to strokes happening. Other things like smoking and drinking can also increase your risk.

What is going wrong?

1. What is fundamentally going wrong in the nervous system is the lack of oxygen or nutrients which creates cells to die at that specific place.


2. There are no particular chemical imbalances besides the vanished blood. Strokes can either be hemorrhagic (15%) or ischemic (85%). Hemorrhagic usually occur from either vascular anomaly or long history of hypertension.

How to treat/prevent strokes?

One way to prevent a stroke is by surgical procedures. Surgery can be done to remove a blood clot or maybe even stop internal bleeding in some cases.

How does it affect the person or the person that has to take care of them?

Strokes can cause loss of movement, speech, memory, and also eye sight. When a stroke occurs it can either attack the right of left side of the brain resulting loss in that side of the body.

Additional facts

1. Up to 80% of strokes are preventable.

2. Strokes are also called "brain attacks".

3. Recovering from a stroke can be a very long process.

4. Family history is a big part of diagnosing a stroke.
