Transient ischemic attacks (TIAs) are mini-strokes caused by decreased blood flow to the brain. They are often warning signs of a stroke to come. These symptoms may range from temporary changes in speech, weakness, or vision to obvious loss of sensation, coordination, or loss of motor function. If you experience any of these symptoms, call 911 immediately and visit a qualified physician for an assessment. You might also have other symptoms, such as confusion or numbness in one or both arms.

The risk of another stroke increases with age. People with high blood pressure and atrial fibrillation are particularly at risk. Smoking and excessive alcohol intake also increase the risk of stroke. The symptoms of CVAs include loss of control of certain muscles, paralysis, or difficulty speaking, swallowing, or using language. Depending on where the stroke occurred, you may experience a combination of these symptoms. Your doctor will also evaluate you for other risk factors, such as high blood pressure and a family history of stroke.

If your symptoms are consistent with a CVA, visit a medical center immediately to be evaluated. The patient may need help with home safety or daily activities. Your health care professional can prescribe a speech therapist to help you communicate. Your speech and memory may be affected as well, and you may also have trouble going to the bathroom or eating. Therapy can help you recover and return to your normal lifestyle. The most important goal of stroke treatment is to prevent the next stroke.

The effects of CVA are usually temporary and not permanent. Some patients experience a temporary loss of vision, similar to seeing a black curtain falling over their eyes. Others experience problems with the opposite side of the body, such as weakness or dizziness. Others may experience one-sided weakness or complete paralysis, making it difficult to speak or understand commands. The severity of the symptoms may depend on the underlying cause of the stroke. This disease has a high mortality rate despite advances in medicine.

A cerebral vascular accident, otherwise known as a stroke, occurs when blood flow to part of the brain is disrupted. When oxygen-rich blood cannot reach the brain, cells begin to die. Because of this, it is important to recognize the symptoms of a CVA and seek medical attention as quickly as possible. The earlier a stroke is detected, the better chance it has of recovery. If left untreated, the symptoms can result in permanent damage to the brain.

The symptoms of a CVA stroke vary, but the main reason for stroke is a lack of blood flow to the affected area of the brain. This happens because a part of the brain is damaged or has blood clots that block its flow. In minutes, a person can experience these symptoms, which will reduce their ability to function properly. The symptoms depend on the location of the stroke and the extent of brain damage. If the symptom is severe, however, the symptoms may last for weeks or even months.

Transient ischemic attacks are usually a sign of a major underlying medical problem. A TIA is often mistaken for a mini-stroke and may be easily dismissed as a temporary condition. However, they are warning signs of a looming and debilitating stroke. One-third of all strokes begin with a TIA, which means time is of the essence. If you experience a TIA, contact a doctor right away.
