What Are the Common Causes of Stroke? - Oren Zarif - Causes of Stroke
There are many possible causes of stroke. Blood clots are one of the most common types of stroke. The problem is that these blood clots can travel through the bloodstream and lodge in an artery in the brain. In some cases, blood clots are the only cause of stroke. Other causes include physical trauma, hypertension, and blood-thinning medications. Regardless of the cause, there are some symptoms that are consistent across all stroke types.

TIA (tiny ischemic attack): This stroke-like condition is caused by a blood clot. This type of stroke is not a full stroke, but it serves as a warning that a stroke is imminent. While TIAs are not categorized as full strokes, they should be treated just as seriously. Approximately 10% of TIA sufferers go on to have a full stroke within three months.

Stroke happens when normal blood flow to the brain is blocked. Without blood flow, brain cells cannot survive. Ultimately, this results in permanent damage. If left untreated, stroke may cause disability or death. Fortunately, many types of stroke can be treated. Although there is no one cause for stroke, early treatment can improve the chance of recovery. Stroke sufferers should be aware of these risks and seek immediate medical care if they are experiencing these symptoms.

A person's risk for a stroke depends on a number of factors. High blood pressure, cholesterol, smoking, and heart rhythm disturbances are all risk factors. A physician's diagnosis of stroke involves the patient's history, blood tests, and imaging tests. If there are any risk factors, mechanical thrombectomy is one treatment option. This procedure is most effective if the clot is detected early. The early treatment of stroke may prevent the symptoms and even save a life.

One of the most common stroke symptoms is loss of motor function. The affected part of the body may be weak or paralyzed on one side. The patient's ability to feel pain and temperature may also be affected by the stroke. Although the onset of a stroke is unpredictable, early treatment is critical for minimizing the damage to the brain. With prompt intervention, the chances of recovery are high. If the stroke is diagnosed and treated early, patients may recover completely and return to their daily routines.

If the symptoms of a stroke develop within the first three hours, it is important to seek medical treatment as soon as possible. The sooner medical treatment is given, the better the chances are of avoiding permanent brain damage and death. Once a patient is stabilized, they will receive a proper diagnosis and be prescribed the appropriate treatment. A person may undergo thrombolytic therapy, which is medication that breaks up clots. Clot retrieval involves mechanical removal of clots through a catheter.

People from certain ethnic groups have a higher risk of stroke. African-Americans are two to three times more likely to suffer a stroke than whites. Women also have an increased risk of stroke if they are taking certain hormone therapies like estrogen. In addition to heart disease, some illicit drugs, aneurysms, and genetic predispositions can all contribute to stroke. Scientists are trying to understand why high levels of homocystine in some populations may increase the risk of a stroke.

Among the preventable causes of stroke, high blood pressure is a major risk factor. Uncontrolled blood pressure affects 75 percent of the population. Managing blood pressure can drastically reduce the risk of stroke. Uncontrolled blood pressure causes the arteries to tear, resulting in scar tissue that traps substances that can cause blockages and weaken arteries. Although age is a risk factor, there are things you can do to decrease your risk.

A complete blood count will show red blood cells and platelets in your system. The results of these tests will help your doctor determine if there is a blockage in the carotid arteries that supply blood to the brain. Other tests will evaluate your heart's function. Thrombolytic drugs, if available, will break up blood clots that have accumulated in your brain's arteries. They will stop a stroke and reduce the damage to the brain.

Other symptoms of a stroke include an inability to smile, difficulty lifting both arms, or a sudden inability to speak. If you suspect a stroke in a loved one, call 911 as quickly as possible. The longer you wait, the longer your brain will be without blood, causing further damage. Fortunately, there are a few easy ways to detect the warning signs of a stroke and prevent its devastating effects. This article will outline some of the causes of stroke and the steps you can take to mitigate the risks.
