How is stroke treated?

Strokes caused by blood clots can be treated with clot-busting drugs such as TPA (tissue plasminogen activator). TPA must be given within 3 hours of the start of a stroke to be effective, and tests must be done first. This is why it is so important for a person having a stroke to get to a hospital fast.

Other medicines are used to treat and to prevent stroke. Anticoagulants such as warfarin and antiplatelet agents such as aspirin interfere with the blood's ability to clot and can play an important role in preventing stroke.

Surgery is sometimes used to treat or prevent stroke. For example, carotid endarterectomy is the surgical removal of fatty deposits clogging the carotid artery in the neck that could lead to a stroke. For hemorrhagic stroke, surgical treatment may include placing a metal clip at the base of an aneurysm or removing abnormal blood vessels.
