Causes of Stroke - Oren Zarif - Causes of Stroke

Strokes can be caused by several factors. Several vascular conditions can contribute to strokes. Listed below are some of the most common causes. A blockage in the artery carrying blood to the brain is known as an ischemic stroke. This prevents oxygen-rich blood from reaching the brain's cells. In addition, plaque can cause a stroke when it ruptures and forms a clot in the artery. In either case, the downstream cells of the brain are deprived of oxygen.

High blood pressure and diabetes are also risks. A person's family's blood pressure may be high, increasing his or her risk. However, certain genetic disorders can also contribute to stroke. For example, a genetic disorder affecting the heart valves can lead to heart problems, thereby increasing the risk of stroke. A person's age may also increase the risk of stroke. African Americans have a higher stroke risk than whites, while their strokes are more likely to occur in later life. In addition, women tend to suffer from a stroke more often than men, and they are more likely to die than men.

Although the symptoms of a stroke can be difficult to spot, they are not uncommon. The main cause is a clot in the artery that is blocking the blood flow to the brain. If this happens, the brain will not receive enough oxygen, and the affected area may die. Even though stroke is one of the leading causes of death in the United States, many can be prevented or reduced with the proper care. Knowing what to watch for and the causes of stroke can help prevent a stroke.

While a clot is the main cause of stroke, other factors can reduce the risk of a stroke. One of the most effective ways to lower a person's risk is to eat healthier foods. Eating a healthy diet and limiting alcohol consumption will help reduce the risk. Also, eating less processed foods is another way to reduce the risk. And if you're already suffering from a clot, consider taking antiplatelets over the counter to prevent blood clots.

In addition to a complete blood count, doctors may perform tests to measure the number of red blood cells, platelets, and other blood components. A complete blood count also measures the amount of glucose in the blood. Various tests are also used to check the clotting function of the blood, including the international normalized ratio, prothrombin time, and partial thromboplastin time. A patient may also undergo a cardiac monitor. Finally, the NIH stroke scale measures the severity of the symptoms.

Another type of clot is known as an embolism, which can start in a large artery and travel downstream to a small artery in the brain. In the event that the blood vessel in the brain ruptures, it causes a hemorrhage and resulting stroke symptoms. The hemorrhage results in swelling of the brain tissues, thereby causing the symptoms. And while ischemic stroke is the most common type of stroke, hemorrhage is the least serious of the two types.

While transient ischemic attacks are less severe, they still require immediate medical attention. Transient ischemic attack (TIA) occurs when blood flow is insufficient for a short period of time. After this period, normal blood flow returns and the symptoms go away without treatment. Unfortunately, stroke is fatal, resulting in an age-adjusted mortality rate of 37.6 per 100,000 stroke diagnoses. Fortunately, doctors have made tremendous strides in managing strokes.

Depending on the severity of a stroke, a child may lose the ability to speak or walk. It may also have problems understanding concepts, reasoning, and making judgments. Some stroke victims may even experience seizure disorders or a combination of these. If treated early enough, a child can recover motor function, speech, and emotional state. Although recovery may be slow, it is possible to regain lost abilities. The sooner a stroke is detected, the better.

Several factors can increase a person's risk of a stroke. Age, sex, smoking history, blood pressure, cholesterol levels, and diabetes are all considered as risk factors. The risk of a stroke is greatest for people with high blood pressure, but some things can accelerate this process. A person with a history of stroke also has an increased risk of having another stroke. Therefore, it is important to reduce your risk of stroke by lowering your blood pressure, smoking, and reducing the amount of fat and salt you consume.
