Stroke
What is it?
Earlier you learned that a heart attack is when a blockage in the coronary artery prevents nutrients and oxygen-rich blood from getting to the heart.
Another risk of plaque and artery blockage is a stroke. This happens in a very similar way to a heart attack; plaque builds up and causes a blockage which prevents oxygen and nutrient-rich blood from reaching parts of the brain which causes a loss of brain function.
A second type of stroke is a hemorrhagic stroke which causes bleeding in the brain, or between the brain and skull, as a result of a weakened blood vessel.
While the initial stroke is an acute event, the effects are usually chronic.

Call 911 immediately if a person is experiencing any of these symptoms.
Signs and symptoms of stroke happen quickly and may include:
- sudden numbness, tingling, weakness, or loss of movement in your face, arm, or leg, especially on only one side of the body
- sudden vision changes
- sudden difficulty speaking
- sudden confusion or trouble understanding simple statements
- sudden problems with walking or balance
- sudden, severe headache that is different from past headaches
Call 911 immediately if a person is experiencing any of these symptoms.
The chronic effects of a stroke are dependent upon how severe the damage is and where in the brain the bleed occurred. The severity of long-term damage is dependent upon a number of things, including:
- location of the bleed
- how quickly treatment occurred
- how fast blood was restored to the area
- the ability of the other parts of the brain to take over for the damaged area
- how quickly rehabilitation was started
