An Overview of The Brain and How It Works
The brain is the control center for the body. It manages functions such as breathing, swallowing,
moving and seeing. Thus, a stroke can affect almost any function of the body.
Just as important,
the brain also controls thinking, emotions and behavior. As a result, a stroke can sometimes
change aspects of a person’s personality.
For the most part, different parts of the brain control different functions. For
instance, in most people, the ability to use language is controlled by the left side of the brain
or hemisphere, so damage to this area will cause difficulty in understanding and/or producing
language. However, functions often overlap in the brain, so that more than one location controls
Stroke often affects many parts of the brain rather than just a single region.
As a result, the effects of a stroke may not always be clearly defined.
