    What are the different types of blood pressure medication?

    Often, to effectively control hypertension or high blood pressure, lifestyle modifications need to be combined with blood pressure medications, such as diuretics, angiotensin-converting-enzyme (ACE) inhibitors, angiotensin-receptor blockers, beta blockers, or calcium-channel blockers. These medications...Read More

    How effective is carotid artery stenting?

    There isn't enough evidence to determine whether carotid artery stenting is safe and effective enough to replace carotid endarterectomy. Reports from two studies delivered conflicting messages. A North American study of 2,500 men and women with narrowed carotid arteries determined that both procedures...Read More

    Does smoking increase my risk of having a stroke?

    The risk of ischemic stroke is twice as high for smokers as for nonsmokers, and smoking quadruples the risk of hemorrhagic stroke.

    Smoking also contributes to many of the other stroke risk factors: it raises blood pressure, reduces the level of beneficial high density lipoprotein (HDL) cholesterol,...Read More

    What is the cerebral cortex?

    At the top of the brain's evolutionary ladder sits the cerebral cortex, which is involved in all forms of conscious experience. It is the large, dome-shaped mass of gray matter that most people imagine when they picture the human brain. The cerebral cortex covers the top and the outermost...Read More

    What is carotid artery endarterectomy?

    When stroke occurs because of a blockage in a carotid artery, surgery to remove the obstruction reduces the likelihood of a recurrence. This surgical procedure, called carotid endarterectomy, is often the best treatment after a transient ischemic attack (TIA) or minor ischemic stroke that results...Read More

    What is a carotid angioplasty and stenting?

    As in the treatment of coronary artery disease, a stent can be used to prop open a carotid artery that has been severely narrowed by atherosclerotic plaque. This procedure, known as carotid angioplasty, is an alternative to endarterectomy. Instead of opening the artery surgically, the doctor inserts...Read More

    Can carotid artery stenosis increase my risk for stroke?

    In many people, the atherosclerotic narrowing of carotid arteries doesn't cause symptoms, let alone stroke. In fact, most strokes are not related to carotid stenosis. One study found that less than 10% of first-time stroke patients have carotid atherosclerosis. So screening for clogged carotids doesn't...Read More

    Who is a candidate for carotid artery stenting?

    Carotid artery stenting is usually considered when someone is a candidate for carotid endarterectomy. Stenting is sometimes considered a "last chance" treatment of very severe narrowings. Even in these circumstances, the benefit and safety of carotid artery stenting have not been demonstrated con...Read More

    What can I expect during carotid endarterectomy?

    When stroke occurs because of a blockage in a carotid artery, surgery to remove the obstruction reduces the likelihood of a recurrence. This surgical procedure is called carotid endarterectomy.

    Carotid endarterectomy is a significant surgical procedure that usually requires one or two days in the...Read More

    How can I prevent a stroke?

    The most important steps you can take to prevent a stroke are:
    • Lower your blood pressure (the single biggest stroke risk factor).
    • Keep cholesterol levels healthy.
    • Stop smoking.
    • Lose weight.
    • Exercise regularly.
    Note: Treatment with blood-thinning drugs, as directed by a physician on a case-by-case basis,...Read More

    How do I know if someone is having a stroke?

    The National Stroke Association has devised the FAST checklist ("Act FAST") to help determine whether a person is having a stroke.

    If the answer to any of the questions below is yes, there's a high probability that the person is having a stroke.
    • Face: Ask the person to smile. Does one side of the face

    What is tissue plasminogen activator (tPA)?

    Thrombolytic therapy is often the first line of defense in treating some forms of ischemic stroke. The drug most commonly given for thrombolytic therapy, recombinant tissue plasminogen activator (tPA), is one of the first genetically engineered medications. Intravenous tPA was developed to dissolve...Read More
