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

What are the causes of stroke? The most common form occurs when a blood clot blocks a major blood vessel in the brain. This blockage may be caused by a blood clot or fatty deposits called plaque. Another type of stroke occurs when a blood vessel bursts in the brain and causes pressure to build in the surrounding brain tissue. As a result, the brain experiences a lot of damage. Ultimately, it may not be possible to recover.

High blood pressure is one of the biggest risk factors for stroke. It is also often the silent killer. It can be difficult to determine the exact cause of a stroke. A healthcare professional must be able to determine the underlying cause quickly. During an initial examination, it is important to note any symptoms a person has experienced.

A stroke patient may experience a sudden headache, but it is rare for them to experience pain. The doctor will confirm the diagnosis of stroke based on a patient's medical history, physical exam, and blood tests. A CT scan or MRI of the brain is a critical imaging study. Initial treatment is supportive, but more invasive procedures may be required. Surgical procedures may include clipping an aneurysm, removing blood clots in the brain, or other interventions to help restore the blood supply.

A stroke can affect motor function in a part of the brain or the entire side. Hemiplegia refers to complete paralysis of one side of the body. Other areas affected include sensory function, the face, the arm, or the trunk. This type of stroke is often the result of a traumatic brain injury that has affected the nervous system. If the symptoms are not treated quickly, the stroke can cause serious consequences. The brain is the most complex computer known to mankind.

There are several other causes of stroke. A stroke can be caused by a burst artery in the brain. Hemorrhaging blood is an artery that ruptures or weakens. The blood can enter the brain or a brain artery and cause a hemorrhage. This blood will then deprive the brain of oxygen and blood and cause swelling. It can also be caused by other factors, including congenital defects in the brain.

A brain clot is another common cause of stroke. A clot forms in an artery in the brain and blocks blood flow to that portion of the brain. This causes a large amount of brain tissue to die without adequate oxygen and nutrients. The brain is similar to a heart attack, but the cause of a stroke differs. Essentially, the clot may have originated in the heart or travel to the brain. Whether the clot has been a result of a heart attack or a brain artery blockage, it is necessary to receive emergency care immediately.

Strokes can happen at any age, but the risk increases as a person ages. High blood pressure is one of the leading causes of stroke, and the body's sensitivity to insulin increases with age. Diabetes is another common risk factor. People with diabetes have a higher risk of having a stroke than people without the disease. Obesity increases the risk of stroke. This condition can affect the heart, which means the stroke will happen faster.

A clot in the retina can result in a temporary loss of vision, which is commonly described as a black curtain falling over the eyes. In some cases, a clot in the carotid artery can cause one-sided weakness or complete paralysis of a part of the body. If a stroke is not treated in a timely fashion, a second one is more likely to occur. This second stroke can be twice as devastating as the first one, which is why it is essential to seek emergency medical assistance.

If you or someone you know has a history of stroke, your doctor will first perform a complete blood count to assess the severity of the affliction. If the stroke is hemorrhagic, the CT is used to determine the type. This test will also determine if there is any bleeding or a mass in the brain that has decreased blood supply. CT perfusion scans can also be done if necessary. An MRI of the brain is not available at all hospitals.
