Transient ischemic attacks (TIAs) are mini strokes caused by a lack of blood flow to the brain. They can be the first symptoms of an oncoming stroke. Symptoms can range from mild changes in speech and mental acuity to obvious loss of sensation and coordination. Stroke symptoms can affect the entire body. Some of these can include speech problems, confusion, or double vision. Other symptoms may be subtle, but can be indicative of a larger underlying problem.

Other symptoms include drooping or numbness on one side of the face, and altered consciousness. A person experiencing a stroke may be unable to speak clearly, and may have difficulty understanding others. If these symptoms persist, the person should seek medical attention immediately. A full physical examination will be conducted by a healthcare provider to check strength, reflexes, and senses. The healthcare provider will also check for bruit in the blood vessels of the neck, a sign of abnormal blood flow. Blood pressure may be high in people suffering a stroke.

The next step in the treatment process involves determining the cause of the stroke. The symptoms of CVAs can vary depending on where the blockage is, and the extent of the brain damage. Diagnosing a CVA can be critical to a stroke victim’s recovery and quality of life. If the symptoms are detected early, however, there may be no lasting damage to the patient. The sooner a stroke victim receives medical attention, the better his or her chances of a recovery. If it is left untreated, however, the chance of a recovery is extremely low and the condition may even cause permanent brain damage.

People who have had a previous stroke are at a higher risk for a second one. Those with a family history of stroke are at a higher risk. People who live in hot climates are more likely to develop a stroke. Several heart tests are performed to check for problems and blood clots. If a blood clot is discovered, the patient is given tPA (clot-busting drug), which disintegrates the blood clot. This medication must be given within four hours of the stroke symptoms.

Although CVA stroke symptoms can vary, the onset of a transient ischemic attack is the first step in treating the condition. It occurs when the blood supply to the brain is interrupted for a brief period. As a result, a clot may form in the brain, cutting off oxygen and nutrients to the brain. Within three to four minutes, brain cells are no longer receiving oxygen, and their function begins to deteriorate. As the symptoms worsen, the patient may suffer from paralysis, or even death.

Other symptoms of a stroke include confusion, difficulty swallowing, writing, and movement. Stroke is a medical emergency, and it is important to seek medical treatment immediately. Early treatment will save a person’s life and minimize the disability caused by the stroke. If the symptoms persist after 3 hours, call 911 or the emergency services of your area. During the first few days after a stroke, doctors will check the patient for vision and movement issues, and may also perform tests to determine whether there are blocked arteries in the brain.

During a CVA stroke, blood vessels in the brain become blocked and a clot develops. This clot may form in the brain or in a different part of the body. Regardless of the cause, it is important to get treatment quickly because the condition may lead to permanent brain damage or even death. If you are suffering from a CVA stroke, you should seek emergency care right away to ensure the best possible outcome.

The most common risk factor for a CVA stroke is high blood pressure, but there are also other causes. People with high blood pressure, diabetes, atrial fibrillation, or heart disease are at increased risk of having a stroke. Smoking is another major risk factor for stroke. Being overweight can also increase the risk. People who smoke also have a higher risk for stroke. Also, stroke survivors have a greater risk of heart disease.

If you have a high blood pressure, you should try to lower it as much as possible. While not a cure for the condition, it will at least decrease your risk of another CVA stroke. Changing your lifestyle and taking medication may be necessary. Increasing your physical activity can help lower your risk for stroke and keep you healthy. It’s also important to avoid smoking. Smoking increases the risk of another stroke. It is important to maintain healthy weight so that your body can fight off clotting.
