Stroke (cont.)
What is the impact of strokes?
In the United States, stroke is the third largest cause of death (behind
heart
disease and all forms of cancer). The cost of
strokes is not just measured in the billions of dollars lost in work,
hospitalization, and the care of survivors in nursing homes. The major cost or impact of a stroke is the loss of independence that occurs in 30% of the survivors. What was a self-sustaining and enjoyable lifestyle may lose most of its quality after a stroke and other family members can find themselves in a new role as caregivers.
What are stroke symptoms?
When brain cells are deprived of oxygen, they cease to
perform their usual tasks. The symptoms that follow a stroke depend on the area
of the brain that has been affected and the amount of brain tissue damage.
Small strokes may not cause any symptoms, but can still damage brain tissue. These strokes that do not cause symptoms are referred to as silent strokes.
According to The U.S. National Institute of Neurological Disorders and Stroke (NINDS),
these are the five major signs of stroke:
- Sudden numbness or weakness of the face, arm or leg, especially on one
side of the body. The loss of voluntary movement and/or sensation may be
complete or partial. There may also be an associated tingling sensation in
the affected area.
- Sudden confusion or trouble speaking or understanding. Sometimes weakness
in the muscles of the face can cause drooling.
- Sudden trouble seeing in one or both eyes
- Sudden trouble walking, dizziness, loss of balance or coordination
- Sudden, severe headache with no known cause
