The first clue that a person may be suffering from a CVA stroke is the development of sudden, or episodic, symptoms. Although these symptoms will often go away within a few hours, they should be immediately evaluated by a physician. These symptoms may include a lack of vision or numbness, difficulty speaking or swallowing, trouble understanding, and difficulty with movement. In some cases, the patient may even have difficulty speaking or understanding what others are saying.

Cerebrovascular accident, or CVA, is a serious medical emergency that involves the blockage or rupture of an artery in the brain. The symptoms of CVA vary, depending on the cause, location, and extent of damage to brain cells. The first symptoms of CVA stroke are dizziness, confusion, and loss of consciousness. The symptoms may also affect a specific part of the body, such as the face or hands.

There are several causes of stroke, but the most common is a blood clot. The clot is caused by a buildup of cholesterol or calcium in the blood vessels of the heart. This buildup can then travel through the bloodstream and lodge in an artery in the brain. It can also result in an aneurysm. Symptoms of a CVA stroke are often mild and can occur with or without other signs of heart failure.

Hemorrhage in the carotid arteries is another common cause of the onset of a stroke. High blood pressure, which can cause clotting of arteries, can also result in hemorrhage. In the case of a hemorrhagic stroke, bleeding may result in a hematoma. This clot can damage brain cells, and the swelling can place additional pressure on surrounding brain tissue.

An axon is a specialized cell that connects neurons. It provides support to other neurons, but the axons in the brain can break down due to axon damage. The loss of axons leads to an increase in the viscosity of blood and an increase in the risk of stroke. Axons in the brain are especially susceptible to ischemia, as they do not have respiratory reserves and depend on aerobic metabolism.

High blood pressure is a major risk factor for stroke. People with a family history of stroke are at a higher risk for a subsequent one. A person with high blood pressure may also have a tendency to become dehydrated, which can increase the risk of a stroke. Smoking and alcohol intake may also increase the risk of a stroke. It’s important to understand the symptoms of CVA stroke so that you can take the proper steps to prevent a future stroke.

A person suffering from a transient ischemic attack, or TIA, should seek immediate medical attention. Though the symptoms of a TIA are similar to those of a stroke, they usually do not last for more than a few minutes. TIAs are important warning signs of a potentially debilitating stroke, and should not be overlooked. The earlier you treat a TIA, the better your chances of surviving a stroke.
