Stem cells have been shown to help in stroke patients. Recovery, if any, occurs gradually over several months to a year or more. Most of the treatment is rehabilitation to try to improve function after the stroke. Ischemic stroke patients are often treated with anticoagulants (blood thinners) in hopes of preventing more clots. Hemorrhagic strokes are sometimes treated to avoid further hemorrhage.Īfter the first few hours, there is no specific treatment for strokes.
Since alteplase breaks up a clot, it can cause severe worsening or death if used with a hemorrhagic stroke. It is essential that CT imaging is done to determine the type of stroke to confirm it is not hemorrhagic prior to using alteplase. If used in the first few minutes to hours, it can avoid or limit any damage to the brain. This drug can break up the clot blocking the blood vessel. If treated in the first few minutes, the damage from an ischemic stroke can be reversed or limited using special drugs (alteplase or tissue plasminogen activator) in an Emergency Room or hospital. Stroke treatment has improved only slowly. Knowing which type of stroke is present is essential in the early treatment of stroke. They occur when a blood vessel leaks and there is bleeding into and around the brain. Hemorrhagic strokes are the less common form of stroke. Ischemic strokes occur when the blood vessel to part of the brain is blocked, typically by a blood clot or a build-up of cholesterol similar to a heart attack. In general, there are two types of stroke, ischemic and hemorrhagic. Since the brain controls all of our movement and sensations, including sight and speech, almost anything can be impacted by a stroke. If the area controlling sensation on the left arm is also involved, the arm will be numb or may have burning or pain sensations as well. For example, if the area controlling movement of the left arm is damaged, that arm will become weak or paralyzed.
This results in a loss of function in the body based on what the damaged area of the brain controls. When that occurs, the brain tissue that loses its blood supply is injured or killed. What is a Stroke?Ī stroke occurs when the blood flow is cut off to part of the brain. Stem cells are showing some real promise for patients who have suffered a stroke. Unfortunately, treatment for stroke remains limited. It is also a leading cause of chronic disability in the United States. Stroke is the fifth leading cause of death in the United States.
