Causes of Stroke

The causes of stroke are a result of difficulties inside the circulatory system when arteries to the brain become blocked or blood vessels within the brain rupture, both of which cause damage to brain cells.

DID YOU KNOW THAT

Strokes are the third most common cause of death and also the second most typical cause of disabling neurological damage. Just in the United States, more than 600,000 individuals have one every year with more than 160,000 causing death. (That's why the Ol' Boomer thought it wise to include the causes of stroke on this website!)

The incidence of these increase with age though about 66% of these happen to people older than 65. Non-lethal strokes have a tendency to be either disabling or cause a loss of use of parts of the body.

Maybe you know a person who has experienced one of these. My own father had a disabling stroke at age 60 which affected his speech and the use of his left arm.

Here's a brief video explaining strokes.


There are two types of strokes

the Ischemic and the Hemorrhagic.


Ischemic Stroke

About 85% of strokes are ischemic where the blood flow to the brain is narrowed by fatty deposits or restricted by a blood clot (fatty deposits within the arteries which break loose).

Named (thrombosis) this in turn reduces the blood supply to a portion of the brain. When this happens the brain cells supplied by that specific vessel typically die.

You've probably heard of a medical condition called atherosclerosis (hardening of the arteries). It is often a prime factor for stroke.

A transient ischemic attack sometimes called a ministroke, while generally not life threatening gives you a warning sign that your vascular conditions are prime for an impending ischemic attack.

A transient ischemic attack (TIA) is usually a short period of symptoms similar to those you'd have in a stroke. Most TIAs last less than five minutes.

PLEASE NOTE: If you've had a TIA, it indicates there is likely a partially blocked or narrowed artery leading to your brain, making you a prime prospect for a major stroke that could cause permanent damage later.

Also, based on your symptoms, it's difficult to know if you are having a TIA or a major stroke. It's likely that half we Baby Boomers who will think our symptoms have gone away are really having a "forever" brain damaging stroke!

Hemorrhagic Stroke

This kind of stroke accounts for the remaining 15% of strokes. It occurs when a blood vessel ruptures inside the brain. This bleeding enables blood to leak into the brain tissue and can trigger scarring, which could then result in seizures.

It is worth noting that hemorrhagic strokes have higher odds of being fatal than do ischemic.



Factors for Stroke

There are many factors for the causes of stroke amongst these are:

Genetics - The history of your family. Is there a history of strokes inside your immediate family including your parents, grandparents or siblings?

Have you received a diagnosis of having atrial fibrillation (afib)? A medical condition where your heart beats irregularly. Did you realize that Baby Boomers with this condition are five times more likely to have a stroke?

Have you or a close family member been diagnosed with Atherosclerosis? A condition where the walls of your arteries are narrowed or blocked by deposits of fatty material.

Do you experience frequent migraine headaches? There is a strong linkage between these and hemorrhagic stroke.

Other serious threat aspects for the causes of stroke are:

  • High blood pressure (hypertension)
  • diabetes
  • smoking
  • and high cholesterol levels to name a few.

In Conclusion

As you can see, the causes of stroke are a result of problems in your vascular (circulatory) system while the effects of stroke are to your neurological (nervous) system.

The results are that those parts of your body that are controlled by the damaged/dead brain cells can no longer function properly - thus the resulting disability or death you hear about when you get news of someone you know having had a stroke.

How do you know if you or another person is having a stroke? You can find out by going to our stroke symptoms page.

Do you know what you can do to help yourself from having a stroke? If not, check out our section about stroke prevention.



By the way, did you know that many of the risk factors for a stroke are also prominent in a medical condition called Metabolic Syndrome which is a good measuring device for the presence of many other serious medical conditions we Boomers are facing?

If you are not familiar with Metabolic Syndrome, I recommend you read our article about it here.
