A stroke is a medical emergency that must be treated immediately. The sooner the patient receives medical treatment, the lower his or her risk of permanent damage to the brain and death. Symptoms may include sudden numbness, weakness, or confusion. A stroke will also cause one side of the face to droop. Additionally, the patient may experience double vision, blurred vision, or drooping of the arm.

Ischemic stroke occurs when blood flow to the brain is obstructed by clots. These clots often form from plaque that has narrowed the arteries, a condition known as atherosclerosis. Another symptom of a stroke is a sudden onset of numbness in one arm or leg. Other symptoms include difficulty speaking, confusion, and balance. In some cases, the stroke is preceded by a transient ischemic attack (TIA), which occurs when blood flow to the brain is decreased temporarily. In the United States, more than 700 000 people experience a stroke each year.

A patient suffering from a stroke should immediately call triple zero (000) and request an ambulance. The symptoms of CVA vary depending on the cause, location, and extent of the brain damage. Patients may experience symptoms such as dizziness, confusion, or nausea and vomiting. Patients may also develop hydrocephalus. These symptoms may be more severe in some cases, but they are generally short-lived and may go undiagnosed.

Another common type of stroke is an ischemic stroke, which occurs when a major blood vessel in the brain is blocked. The blockage may be caused by a blood clot or a buildup of fatty deposits and cholesterol (called plaque). If left untreated, a stroke can lead to permanent brain damage and even death. High blood pressure and high cholesterol are common risk factors for a stroke. Lifestyle changes, such as physical activity, may help reduce your risk of a stroke.

Other symptoms of a stroke include cognitive changes, such as memory loss and difficulty reasoning, understanding concepts, or controlling emotions. In addition, people may feel pain in certain areas, such as their arms or legs. They may also experience numbness or tingling sensations. If you are experiencing any of these symptoms, see your doctor immediately to get the proper diagnosis. In some cases, medications can help improve the condition and reduce the risk of a future stroke.

A stroke can occur at any age. It is most common among people who have high blood pressure. Other risk factors include diabetes, atrial fibrillation, or smoking. Smokers have a higher risk of stroke than nonsmokers. They also have a higher risk of suffering a CVA stroke than nonsmokers. These symptoms include difficulty speaking, vision problems, confusion, and even paralysis.

A TIA is a warning sign of an impending stroke. TIA symptoms are a result of a partial blockage of an artery to the brain. TIA symptoms usually last for a few minutes and may go away within 24 hours. A TIA can be a sign of an upcoming CVA stroke, so it is important to take immediate action. For instance, bleeding in the brain cells can cause the arm to weaken.

A CT scan will show if there are any clots or other abnormalities. An MRI will provide a more detailed picture of the brain. An MRI is more sensitive than a CT scan and is used in the event of a stroke. An electrocardiogram, or EKG, is an electrical trace of the heart. A disturbed heart rhythm can cause a stroke. While these are only a few of the symptoms of a stroke, they are all important.

Medications can help prevent or reduce the chances of a stroke. Aspirin and blood thinners are two common stroke treatments. Patients may also need treatment for high blood pressure, smoking, or other conditions that put them at risk for stroke. Some patients may need two medications or undergo a stroke surgery. This surgery removes the blood clots and relieves pressure on the brain. A stroke can affect the patient’s life, but with treatment and time, recovery can occur.

If you suspect that you or someone you know is having a stroke, call 9-1-1 immediately. Do not drive to the hospital. The ambulance crew will begin lifesaving treatments on the way to the emergency room. Once at the hospital, the stroke team will assess the symptoms and diagnose the cause of the stroke. Once diagnosed, a treatment plan may be prescribed. The recovery period depends on the severity of the stroke. Sometimes, a rehabilitation plan will be recommended for the patient to get back to normal.
