Currently in the United States, every 40 seconds someone suffers from a stroke. This translates to nearly 800,000 people per year, of which 140,000 result in death. Given our country’s propensity for fast food and bingeable TV programs, this isn’t that surprising. However, we should be considering that this speaks volumes about our healthcare and culture. Strokes are now the third leading cause of death in the country, but it’s also one of the most preventable. Strokes are usually induced by people who have high blood pressure, smoke or chew tobacco, or who have diabetes.

In fact, risk of stroke increases twofold every decade after the age of 55. In honor of National Stroke Awareness month, we’d like to share some helpful information on what a stroke is, what causes strokes, and how to prevent a stroke from happening for an elderly person.

What is a Stroke?

A stroke is what occurs when the blood flow to the brain gets cut off. Similar to a heart attack, you can think of strokes like “brain attacks”. When the brain cells that need oxygen are deprived of this vital blood flow, will shut off and die. A stroke is a serious occurrence because the death of brain cells can immobilize the victim and possibly result in permanent brain damage. There are two types of strokes.

Ischemic Stroke

An ischemic stroke is similar to a heart attack in that a clot forms in the blood vessels surrounding the brain. These can also occur when too much plaque from fatty deposits and cholesterol block blood vessels. Ischemic are the most common type of stroke and account for 80% of all strokes.

Hemorrhagic Stroke

This type of stroke occurs when a blood vessel in the brain breaks open. This rupture leads to blood seeping on to brain tissue, which can cause damage to brain cells. Hemorrhagic strokes typically occur because of high blood pressure, or aneurysm, which is a thinness in the walls of a blood vessel.

The effects of the stroke depend on where the stroke occurs in the brain. Some areas control motor function and some control memory, so stroke victims may experience temporary or permanent loss of mobility in a portion of their body, or lose the ability to speak. Some people recover from strokes without permanent damage, but more than ⅔ of stroke victims continue with some sort of disability. It’s important to recognize the signs of a stroke so you can treat it as quickly as possible.

Signs of a Stroke

Knowing the signs of a stroke can save a life and prevent lasting brain damage. The sooner you can get treatment for a stroke, the better chances you have of saving brain cells and preventing further damage to the brain. A helpful acronym for knowing when to call emergency services is FAST.

Other common signs and characteristics are:

  1. Onset weakness or paralysis of half or part of the body
  2. Numbness on one half or part of the body
  3. Sudden change in level of awareness
  4. Partial vision loss
  5. Double vision
  6. Sudden severe headache with no known cause
  7. Difficulty speaking or understanding speech
  8. Unbalance and vertigo

If you suspect or are unsure if someone may be having a stroke, it is wise to call 9-1-1 anyway. However, the safest method is to use preventative guidelines to make sure you never have a stroke in the first place. There are plenty of healthy tips and tricks you can use to reduce your chances of stroke, but there is no guarantee that you will never have one, especially if you have a family history of high blood pressure or strokes.
