Although there are no specific symptoms that indicate that someone has had a CVA stroke, they often are a warning sign. Transient ischemic attacks (TIAs) occur when blood flow to the brain is reduced. Symptoms of TISAs may range from slight changes in speech and mental acuity to numbness, blacking out, or double vision. However, if you notice any of these symptoms, you should immediately contact a qualified physician and seek medical attention.
The medical term for this condition is a CVA (cerebrovascular accident), and it is caused by a blockage or rupture of a blood vessel within the brain. Knowing the symptoms of a CVA stroke is extremely important as any minute or second counts. While a CVA can cause permanent damage to the brain, the earlier it is treated, the better chance of a full recovery. In many cases, if the symptoms of CVA stroke are recognized early enough, a victim can recover fully and return to normal life.

During the initial stages of stroke recovery, individuals with CVA symptoms may need assistance with daily activities, home safety, and communication. They may need assistance with eating and toileting, or may have difficulty thinking or memory. Therapy may help a person deal with the symptoms of their stroke and to prevent recurrence of the condition. In the long run, though, the goal of treatment is to prevent another stroke. Luckily, the recovery process can be incredibly rewarding when the stroke symptoms are managed.

TIA and CVA symptoms can be difficult to identify and are not the same. There are several differences between the two, however. For one, TIAs are not immediately apparent, whereas CVA symptoms may be more severe. Patients who experience a CVA stroke typically had a previous TIA. In addition to visual problems, patients may also suffer from dizziness, weakness in one side, or even complete paralysis. The occurrence of these symptoms is usually the result of a blood clot, not a stroke itself.

If you have transient ischemic attack (TIA), a mini-stroke, or “mini-stroke,” you should seek medical help immediately. While TIA symptoms usually go away on their own, they are still a warning sign of a potentially debilitating stroke. In fact, one-third of all strokes occur before the onset of TIAs, so it’s critical to act quickly.

The most common risk factor for a stroke is high blood pressure. People with atrial fibrillation, diabetes, or high cholesterol are most at risk. Smoking, drinking too much alcohol, and eating too much salt increase a person’s risk. A person may also experience changes in language, speech, or sensations. In some cases, stroke victims may experience an acute onset of symptoms. And even if the symptoms aren’t immediately apparent, the person will likely need medical care.

Depending on the type of stroke, people suffering from a CVA may not have any immediate symptoms. However, if there is a loss of blood supply to part of the brain, that part of the body may become paralyzed. To get help, the person must call 9-1-1 to access emergency care. Within three to four and a half hours, the affected person can be given a drug that will break up the clot and restore blood flow to the brain.

When blood flow is impaired to a part of the brain, it is called an ischemic stroke. An ischemic stroke can happen for a variety of reasons. A blood clot in an artery or atherosclerosis (the narrowing of arteries) may cause the blockage. The blocked blood flow causes damage to cells in the affected part of the brain. The cells in the area of the brain are starved for oxygen and blood and die as a result.
