Ischemic Stroke and Treatment
There are two primary types of stroke, ischemic and hemorrhagic, with ischemic being the more common of the two. The ischemic stroke occurs if an artery supplying blood to the brain becomes blocked. Blood clots are often the cause of these blockages that lead to ischemic strokes.
There are two types of ischemic stroke:
In both types of ischemic stroke, blockage, whether by a blood clot or a fatty plaque, causes the stroke.
What Causes Ischemic Stroke and TIAs?
Since blockages of arteries cause ischemic strokes and TIAs, any condition that leads to increase of fatty plaques in the blood vessels or the formation of blood clots in the bloodstream can increase the risk of this form of stroke, including:
Treatments for Ischemic Stroke and TIAs
If you get treatment within three or four hours of onset of symptoms, your doctor may inject you with a plasminogen activator (tPA) that breaks up blood clots in the arteries of the brain. It should be given as soon as possible, for best results.
If a tPA cannot be administered, you may get antiplatelet medication, which stops platelets from clumping together, reducing risk of dangerous blood clots. Aspirin may be given within 48 hours of stroke for this reason.
Anticoagulants (so-called “blood thinners”) may also be given in order to minimize blood clots and prevent new clots from forming.
In instances where there is blockage in the carotid artery, your doctor may recommend one of two procedures:
These procedures, coupled with changes in lifestyle, may greatly lower the risk of stroke in people with carotid artery disease.
