What’s That? How a Stroke Occurs

I took an informal survey of friends and family this week – those with parents of the age to consider elder care of some sort.  I was trying to understand their knowledge of popular diseases and medical conditions.  Specifically, I was trying to determine two things:

  1. What percentage of them were familiar with common diseases and medical conditions
  2. What percentage of them actually knew what happens to the body and/or what causes these diseases and conditions

I was not surprised that the vast majority of my participants had basic familiar with a number of common diseases.  I was surprised, however, that many were unsure of what actually happens during the course of many medical conditions.

With that in hand, I’d like to introduce a new series of articles called “What’s That?”

Each What’s That? post will provide background information on a disease or medical condition impacting those in assisted living.  An illustrated video (courtesy of CareFlash) will accompany the post, providing a multimedia explanation of just what’s happening when a medical condition occurs.

What’s That?  How a Stroke Occurs

As with all organs in the body, the brain needs oxygen and nutrients in order to function properly. These life-sustaining products are delivered to the brain via the blood that travels through the circulatory system.  A stroke occurs when there is a lack of blood to a portion of the brain, resulting in tissue death and loss of brain function. A stroke can be caused by a ruptured blood vessel, such as an aneurysm, or by an embolism, which is a small free-floating clot or particle that becomes lodged in one of the arteries of the brain and interrupts blood flow.  Depending on which area of the brain is affected, a stroke can cause speech impairments, paralysis, unconsciousness, or even death.
