What Are the Causes of Stroke? - Oren Zarif - Causes of Stroke

If you're wondering what the causes of stroke are, read on. Stroke symptoms may include weakness, numbness, facial droop, or speech difficulties. They may also last just minutes, which gives you the opportunity to seek out a possible cause and treat it quickly. But don't let the temporary symptoms fool you. You may still need to see a doctor as soon as possible to avoid serious damage. Here's what to do in the event you notice symptoms of stroke:

Age is one of the major causes of stroke. People over the age of 55 have a doubling of their risk. In childhood, stroke is most likely to happen during the perinatal period, which lasts from the last few months of fetal life until birth. Also, men are more likely to develop a stroke than women of the same age. And while women are less likely to develop a stroke, they are also more likely to die from it.

To confirm whether someone is having a stroke, the doctor will perform a brain scan. The only way to know for sure what type of stroke is occurring is in a hospital. In the meantime, a physician can start treatment as soon as a suspected stroke symptoms occur. However, the symptoms of stroke can be a little harder to detect than a stroke in adults. A brain scan will tell doctors whether the symptoms are related to a heart problem or to a stroke.

A lack of oxygen prevents neurons from breaking down glucose completely, resulting in harmful waste products. These waste products can harm the neurons further, even after the blood flow has been restored. Meanwhile, free radicals form, causing further damage. As the brain loses oxygen and nutrients, the symptoms of stroke manifest themselves in a wide range of ways. But no matter what the symptoms of a stroke are, a proper diagnosis is the first step.

A blockage in a blood vessel supplying the brain is the most common cause of a stroke. A clotted blood vessel robs the brain of blood and oxygen, which causes the symptoms of stroke. The blood vessel can be blocked with a clot and can rupture. When this happens, a person's brain tissue can begin to swell and die. The symptoms of a stroke depend on the type of clot.

In addition to a clot, a person may experience a transient ischemic attack. This type of stroke is usually temporary, and treatment is geared toward minimizing the risk of another stroke. However, it's important to get a proper diagnosis to prevent the stroke from progressing. If you've had a transient ischemic attack (TIA), call 9-1-1 immediately. A medical emergency can save your life.

If a person has experienced a stroke, medical treatment should begin immediately. Treatment options include intravenous lines and oxygen. Blood tests and non-contrast CT scans may be necessary, depending on the severity of the underlying conditions. Thrombolytics (blood-clot-busting medications) and clot retrieval, mechanical removal of a clot from the large arteries, are common. The aim is to reduce the extent of brain damage and to maximize quality of life.

Other common causes of stroke include bleeding disorders, such as hemophilia or coagulation disorders. A heart condition called atrial fibrillation may also increase your risk of a stroke. While it is rare for a person to have a bleeding disorder during a stroke, if it is present, it can result in serious damage to the heart. Fortunately, you can prevent stroke with lifestyle changes, and many risk factors can be controlled or reduced.

Hemorrhagic stroke is the result of bleeding from an artery. This can occur due to thrombosis, embolism, or severe narrowing of the arteries leading to the brain. A hemorrhagic stroke is more likely to occur in a person who has suffered a previous head injury. Acute brain damage from a heart problem can also lead to a stroke. So what causes a stroke?

Among the most common causes of stroke, high blood pressure and diabetes are known to increase your risk. If you have high blood pressure, it can damage blood vessels in the brain. Smoking can increase your risk of a stroke by almost doubling. To lower your risk of a stroke, quit smoking. This habit will lower your blood pressure, reducing your risk by up to 50%. In addition to these common risk factors, you should make a commitment to improving your oral health.
