Stroke is the fourth leading cause of death in the United States and one of the leading causes for admission into long term care in North Dakota. It occurs when a clot blocks the blood supply to part of the brain or when a blood vessel in or around the brain bursts. In either case, parts of the brain become damaged or die because it cannot get the blood and oxygen it needs.
You may be able to prevent stroke by controlling your blood pressure, reducing your blood cholesterol levels and stopping tobacco use. Reducing your risks and knowing the signs and symptoms of stroke can lessen the chance you have a stroke and improve outcomes in the event a stroke does occur.
Types of Stroke
Ischemic stroke occurs when blood flow to the brain becomes blocked by blood clots or fatty deposits called plaque in blood vessel linings. This type of stroke accounts for 85 percent of all strokes.
Hemorrhagic stroke is the most serious type of stroke. It occurs when a blood vessel in the brain bursts. Blood accumulates and compresses the surrounding brain tissue.
Transient Ischemic Attack (TIA), also known as a "mini-stroke" or “warning stroke,” can happen before a major stroke and should be taken very seriously. They occur when the blood flow to part of the brain is blocked or reduced for a short period of time, resulting in temporary symptoms similar to those of a stroke.
A mini-stroke may not leave noticeable damage, but it is important to talk to your doctor immediately. A person who has a mini-stroke is 9.5 times more likely to have a stroke. Recognizing and treating a mini-stroke immediately can reduce your risk of a major stroke.
Remember, the chance that you will survive and recover
from a stroke is higher if you get emergency treatment right away.
