Brain Stroke Overview

A stroke occurs when a party of the brain is deprived of oxygen-rich blood due to several mechanisms. Typically, a stroke occurs when an artery is blocked, either by narrowing of small arteries in the brain or hardening of the arteries leading to the brain (called atherosclerosis). In some cases, stroke may be the result of a stroke, who traveled from the heart to the brain. Strokes can be ischemic (when caused by a blood clot) or hemorrhagic (bleeding when ruptured aneurysms in the brain).

The U.S. National Institute of Neurological Disorders and Stroke (NINDS) established a list of stroke symptoms that patients experience. Symptoms of stroke occur suddenly and in the case of a transient ischemic attack ("mini-stroke"), which disappear within 24 hours but otherwise tend to be permanent. Numbness or weakness in the face, arm and leg on one side of the body, difficulty seeing, speaking or understanding, along with severe headaches are the symptoms first hit. Patients are often confused, you can balance or coordination loss and has difficulty walking and feel dizzy. Stroke is a medical emergency for the recognition of the signs as soon as they occur is very important for the patient's life.

There are medications available to treat stroke. Heparin or aspirin is recommended for patients who have suffered a stroke due to its ability to thin the blood. However, tissue plasminogen activator (TPA) is the most common treatment for stroke. In fact, involves the injection of TPA into a vein in the arm as soon as possible, and the sooner it is administered, the better the results.

The most important and difficult is the treatment of stroke recovery. As soon as the patient is no longer seriously ill he or she should follow rehabilitative therapy to regain their functional abilities. Therapy can be followed either in a specialized rehabilitation hospital or a nursing home. During recovery, the patient should follow speech therapy to regain his ability to speak and swallow occupational therapy to regain dexterity in their arms and physical therapy to improve strength and walking. Rehabilitation process includes family education designed to guide the family, given the challenges they will face.

Stroke Prevention is the best for a patient could do. Those who suffer from diabetes, who smoke or have high blood pressure and high cholesterol levels are predisposed to developing this condition. People at risk should regularly check your blood pressure and cholesterol levels and try to keep them under control. A stroke often occur without warning, so it is very important for people who may suffer from a stroke follow your doctor's advice.

Some strokes can be caused by a brain tumor. Brain cancer and tumors, especially primary (those that develop in the brain) can lead to complications such as stroke, in special circumstances
