Causes of Cerebral Infarction - Oren Zarif - Cerebral Infarction


There are many causes of cerebral infarction. This article provides information about some of the most common types and their symptoms. Learn how to recognize the signs and symptoms of infarction and what to do if you suspect it is happening to you. If you suspect cerebral infarction, call your doctor as soon as possible. You may need urgent medical treatment, such as surgery, to save your life. This article was written with your health in mind, so please be sure to read the entire article.

The first step in treating a cerebral infarction is to determine the exact type of infarct and its severity. Ischemic stroke is a form of ischemia that may be mild or severe. This type of brain damage occurs when blood flow to a specific region is reduced or halted altogether. It may last from 15 to 30 minutes. It may be fatal or only mildly disabling. Once diagnosed, the patient will be treated with medication to prevent brain damage and reestablish brain function. The goal of treatment is to reduce the brain's temperature to prevent the infarcted area from dying. Surgical intervention is an option in the case of moderate cerebral infarction.

There are several types of treatment for cerebral infarction. Early intervention is critical for the best chance of survival. Initial diagnostic tests include CT or MRI scanning of the brain to identify the damage and underlying cause. Angiograms can reveal a blockage or a stroke. An autopsy may also provide clues about the duration of the infarction. A recent breakthrough in the treatment of cerebral infarction is the use of thrombolytic drugs. If a stroke has been diagnosed within three hours of onset, patients may be offered intravenous rtPA.

A coronal section through the parietal lobes demonstrates a wedge-shaped area of expansion, indicating a hemorrhagic infarction. In addition, a wedge-shaped zone of parenchymal loss is indicative of a remote infarction. A transverse section of the pons reveals atrophy of the pontine base, due to Wallerian degeneration of the corticospinal tract.

Ischemic stroke is the most common type of stroke, accounting for 87 percent of all cases. A clot forms at a fatty plaque within a blood vessel, or at another site in the circulatory system. The clot travels to the brain and blocks the flow of blood in the area. The symptoms of a transient ischemic attack are similar to those of a full stroke, but are temporary.

While a silent cerebral infarction is usually accompanied by a history of a stroke, it is sometimes diagnosed without a stroke. These infarcts may have occurred without symptoms. These symptoms are transient and may not have been recognized. They are common, though, and appear on a CT scan only in about 15 percent of patients suffering from transient monocular blindness or TIA. Magnetic resonance imaging, which is more sensitive, is also used to detect silent cerebral infarcts.

Neuroimaging is done to exclude other conditions such as subdural or epidural hematomas and tumors. MRI is used to assess collateral blood flow in infarct and ischemic tissues. MRI is more time-consuming and less sensitive than CT but is often more specific than CT. But whatever your symptoms, don't delay treatment. A delay in diagnosis can have a significant impact on your prognosis.

Although a large proportion of patients with cerebral infarction are elderly, some people are still at risk. In fact, more than 10% of patients under 55 years of age are younger than 55. Studies on the causes of this type of stroke have focused on young adults. However, few studies have quantified risk factors. Therefore, early detection and prevention of these conditions are vital. You can take steps to reduce your risk of developing this condition and improve your quality of life.

There are several types of infarction in dogs. Two common types are ischemic and hemorrhagic. The former is caused by ruptured blood vessels, while the latter occurs when an aneurysm bursts and blocks arteries. TIAs usually resolve spontaneously, but about 10 to 15 percent go on to develop major stroke within 3 months. You should seek immediate medical attention if you notice these symptoms.

In acute ischemic stroke, your doctor may use a catheter to remove the clot from the brain. This catheter is inserted through an artery in the neck. A tiny syringe is then used to remove the clot. Then, your doctor may place a coil-like device around the aneurysm to stop the bleeding and prevent it from growing back. The procedure takes time, but it is worth it to save your life.
