4 Things You Need To Know About The Causes And Prevention Of Stroke
Well, for us to understand stroke, we need to know what it is. Webmd said stroke is a medical emergency and a leading cause of death in the U.S. It occurs when a blood vessel in the brain bursts or, more commonly, when a blockage develops. Without treatment, cells in the brain quickly begin to die. The result can be serious disability or death. If a loved one is having stroke symptoms, seek emergency medical attention without delay.
What then are the symptoms of stroke?
These signs may include:
Sudden numbness or weakness of the body, especially on one side.
Sudden vision changes in one or both eyes, or difficulty swallowing.
Sudden, severe headache with unknown cause.
Sudden problems with dizziness, walking, or balance.
Sudden confusion, difficulty speaking or understanding others.
So when an individual has stroke, he arrives in the ER. The first step is to determine which type of stroke is occurring. There are two main types and they are not treated the same way. A CT scan can help doctors determine whether the symptoms are coming from a blocked blood vessel or a bleeding vessel. Additional tests may also be used to find the location of a blood clot or bleeding within the brain.
There are essentially two types of Stroke. Namely Ischemic Stroke. This is the most common type of stroke is known as an ischemic stroke. Nearly nine out of 10 strokes fall into this category. The culprit is a blood clot that obstructs a blood vessel inside the brain. The clot may develop on the spot or travel through the blood from elsewhere in the body. Also, we have Hemorrhagic Stroke. They are less common but far more likely to be fatal. They occur when a weakened blood vessel in the brain bursts. The result is bleeding inside the brain that can be difficult to stop. What then are the causes of Stroke in a patient?
A poor diet may increase the risk for stroke in a few significant ways. A diet high in fruits, vegetables, whole grains, and fish may help lower stroke risk.
Old age and gender
Some stroke risk factors are beyond your control, such as getting older or having a family history of strokes. Gender plays a role, too, with men being more likely to have a stroke. However, more stroke deaths occur in women. Finally, race is an important risk factor. African-Americans, Native Americans, and Alaskan Natives are at greater risk compared to people of other ethnicities.
In order to prevent stroke, you will need to do the following
Change of Lifestyle
People who have had a stroke or TIA can take steps to prevent a recurrence:
Exercise and maintain a healthy weight.
Limit alcohol and salt intake.
Eat a healthier diet with more veggies, fish, and whole grains.
For people with a high risk of stroke, doctors often recommend medications to lower this risk. Anti-platelet drugs, including aspirin, keep platelets in the blood from sticking together and forming clots. Anti-clotting drugs, such as warfarin, may be needed to help ward off stroke in some patients. Finally, if you have high blood pressure, your doctor will prescribe medication to lower it.
In some cases, a stroke results from a narrowed carotid artery — the blood vessels that travel up each side of the neck to bring blood to the brain. People who have had a mild stroke or TIA due to this problem may benefit from surgery known as carotid endarterectomy. This procedure removes plaque from the lining of the carotid arteries and can help prevent additional strokes.
Balloon and Stent
Doctors can also treat a clogged carotid artery without major surgery in some cases. The procedure, called angioplasty, involves temporarily inserting a catheter into the artery and inflating a tiny balloon to widen the area that is narrowed by plaque. A metal tube, called a stent, can be inserted and left in place to keep the artery open.
