What Causes Stroke?

A stroke happens when:

1. A blood clot forms in an artery in the brain that is already narrowed by cholesterol deposits.

2. An artery in the brain is blocked by a blood clot, piece of fat or air bubble traveling in the blood from another part of the body.

3. An artery in the brain bursts and bleeds. This may be due to high blood pressure, head injury or a weak artery wall from birth.

4. An artery in the brain is compressed by a tightening of the artery wall or a tumors.

It may be possible to prevent a stroke and its complications if you a see a doctor as soon as you notice any of these warning signs:

1. temporary weakness or numbness occurring suddenly in one arm or leg on one side of the face

2. temporary difficulty in speaking or slurring of speech

3. sudden poor vision or ‘blackout’ in one eye

4. unexplained headaches or a change in the usual headache pattern

5. temporary dizziness or fainting.

You should see a doctor as soon as you suspect a stroke.
