What is a Brain Stroke? - Oren Zarif - Brain Stroke

What is a Brain Stroke? A stroke is a sudden, unexpected change in the flow of blood to the brain or spinal cord. This change can be caused by a ruptured blood vessel or damage to a brain tissue. A clot, or emboli, can also block the blood flow, resulting in a stroke. Sometimes, the brain tissue is so damaged that the blood flow is slow and the body will not feel the clot.

When a patient is suffering from a stroke, the first step is establishing intravenous lines, administering oxygen, and ordering appropriate blood tests and CT scans. The health care professional will evaluate the clinical diagnosis and determine the appropriate treatment for the patient. Treatment options may include thrombolytic therapy, which aims to break up clots, or clot retrieval, which is mechanically removing a clot through a catheter.

Symptoms of a stroke can include loss of vision, speech, or balance, or a combination of them. The location of the injury is crucial. The location of the stroke is critical to the outcome of treatment. Patients with a stroke often experience temporary paralysis or weakness of one side of their body, as well as difficulty speaking and understanding speech. Some may not even recognize that they're experiencing a stroke, so it is important to see a doctor right away.

Depending on the location of the stroke, treatment may vary widely. The brainstem is located right above the spinal cord, and it controls many vital life-support functions. It controls major nerves that control facial movement, chewing, and swallowing. A brainstem stroke can be fatal, but some survivors may experience a neurological condition known as Locked-In Syndrome. Another important factor is the fact that the human nervous system is neuroplastic, meaning that brain cells will keep growing and changing, even after a stroke.

The most common cause of a stroke is the blockage of an artery to the brain. When this happens, the brain is deprived of blood and oxygen. The clotting process begins. As the blood vessel narrows and becomes blocked, a clot forms. Once the blood is blocked, the brain cannot receive oxygen or nutrients. The patient's condition will worsen as the clot spreads throughout the brain.

Rehabilitation is an extensive program to restore function and compensate for permanent losses. Although only 10% of stroke survivors go on to regain function, most can return home after undergoing appropriate therapy. A team of medical professionals coordinates rehabilitation, including a neurologist, physiatrist, physical therapist, occupational therapist, nutritionist, and a mental health professional. If the stroke is severe, a patient may require longer stays in the hospital.

MRI and CT are two common tests used to diagnose a stroke. CT is an important test for determining the underlying cause of the stroke. MRI is a popular alternative but may not be available in all hospitals. In addition, a CT scan is often used to diagnose ischemic stroke. In the case of an acute stroke, a CT scan can also show signs of a hemorrhagic stroke.

Because of the complexity of the human brain, a stroke can affect different areas of the body.

The left side of the brain controls speech and voluntary motor movements, whereas the right side controls balance. A stroke in this part of the brain can cause memory loss and affect any other part of the body. Some strokes result in full or partial paralysis in the right side of the body. In addition, survivors may exhibit unusual language use and cautious behavior.

A transient ischemic attack, or TIA, is a short-lived form of a stroke. It is caused by a disruption in the blood supply to the brain. This type of stroke requires immediate medical attention. It provides the best chance of treatment. If you have a TIA mini-stroke, the best thing to do is get the right treatment at the right time. And TIA can help you avoid a stroke entirely.
