Stroke involves the arteries that go to and inside the brain. This disease is the fifth death cause and also a disability cause in the United States.
Ischemic and hemorrhagic are the two main types of strokes. The former happens more frequently and it is triggered by a contracting or blocking of arteries that lead to the brain. This means the blood flow is highly reduced.
The latter does not occur that frequently and is activated by bleeding in the brain.
Oxygen and nutrients are brought to the brain by blood vessels. When the blood vessels get blocked or burst, a stroke happens. Then part of the brain does not receive the needed blood and oxygen, so it and brain cells die.
Many body functions are controlled by the brain. It is a complex organ and if the blood flow can’t get to the area that directs a particular body function, that body part won’t be able to function properly.
You need to get medical help once you recognize the warning stroke signs. This is important because it can lower the risk of seriously damaging the brain and increase your recovery chances.
Moreover, the signs and symptoms of a stroke may differ from one person to another. It depends on the type of stroke, the amount of damage and the brain part that has been affected.
