Strokes are medical emergencies and treatment needs to begin immediately. Depending on the type of stroke, treatment may include medicines (such as tissue plasminogen activator (tPA) or anticoagulants/antiplatelets) and procedures (such as carotid endarterectomy or carotid artery angioplasty). Surgery—such as aneurysm clipping and coil embolization or arteriovenous malformation repair—may be needed to treat a hemorrhagic stroke. Making lifestyle changes can help treat and control risk factors for a stroke.
