A stroke happens when the blood supply to a part of your brain is suddenly interrupted, causing a damage to the brain tissue. Most strokes happen because a blood clot blocks a blood vessel in the brain or neck. A stroke can cause movement problems, pain, numbness, and problems with thinking, remembering, speaking.
Some people also have emotional problems,such as depression, after a stroke.
If you have diabetes, your chances of having a stroke are 2 to 4 times higher than in people who don’t have diabetes.
How do I know whether I’m at high risk for a stroke?
Having diabetes raises your risk for stroke. But your risk is even greater if
• you’re over age 55
• your family background isAfricanAmerican
• you’ve already had a stroke or a transient ischemic
attack (also called a TIAor a ministroke)
• you have a family history of stroke or TIAs
• you have heart disease
• you have high blood pressure
• you’re overweight
• you have high LDL(bad) cholesterol and low HDL (good) cholesterol levels
• you smoke
How can I lower my risk of having a stroke?
Lower your risk by keeping your blood glucose (sugar), blood pressure, and cholesterol on target with healthy eating, physical activity, and, if needed, medicine. And if you smoke, quit. What are the warning signs of a stroke?
Typical warning signs of a stroke develop suddenly and can include
• weakness or numbness on one side of the body
• sudden confusion or trouble understanding
• trouble talking
• dizziness, loss of balance, or trouble walking
• trouble seeing out of one or both eyes
• double vision
• A severe headache
How is a stroke diagnosed?
A number of tests may be done if a stroke is suspected:
• CT and MRI tests use special scans to provide images of the brain.
• An ECG (electrocardiogram) provides information on heart rate and rhythm.
• An ultrasound examination can show problems in the carotid arteries, which carry blood from the heart to the brain.
• In a cerebral arteriogram, a small tube is inserted into an artery and positioned in the neck. The health care provider injects dye into the artery. Then the provider takes X rays to look for narrowed or blocked arteries
What are the treatments for stroke?
Treatment you need right away
“Clot-busting” drugs must be given within hours after a stroke to minimize damage.
Surgical treatments you may need
Several options for surgical treatment of blocked blood vessels are available. These include
• Carotid artery surgery, also called carotid endarterectomy removes buildups of fat inside the artery and restores blood flow to the brain.
• Carotid stenting can remove a blockage in a blood vessel to the brain. A small tube with a balloon attached is threaded into the narrowed or blocked blood vessel.
Then the balloon is inflated, opening the narrowed artery. A wire tube, or stent, may be left in place to help keep the artery open.
Treatment following a stroke includes treatments and exercises to restore function or help people relearn skills.
Physical, occupational, and speech therapy may be included, as well as psychological counseling. Steps to prevent future problems should include quitting smoking, healthy eating, physical activity and medicines to manage blood glucose, blood pressure, and cholesterol levels.
