The brain is made up of two sides or hemispheres. Stroke, in most cases, affects one side of the brain, which means that stroke to the left side of the brain affects the right side of the body and stroke to the right side of the brain affects the left side of the body.
There are various changes that may happen after a stroke. Some problems are typical to right-sided stroke, some left-sided stroke, and some problems are common to either side.
