Certain ethnic groups are at a higher risk of having a stroke than other people. African Americans are particularly at increased risk, with their age-adjusted incidence two to three times higher than other groups. The incidence of stroke has decreased slightly in whites since the 1990s, but it has not reduced at all for blacks. A family history of stroke may also increase your chances of suffering one. Some genetic disorders can also lead to a stroke.

A clot in a blood vessel that supplies the brain can cause temporary visual loss - sometimes described as a black curtain falling. If the clot is in the carotid artery, it can result in complete paralysis of one side of the body. People can also experience speech or movement problems on the opposite side. If you are suffering from these symptoms, it is important to seek medical attention immediately. The symptoms of a stroke can be life threatening if you are not treated promptly.

Among the most common signs of a stroke in children is a loss of speech. Because the speech center is located in the left half of the brain, a stroke in this part of the brain can affect your ability to speak. Another symptom is weakness on the right or left side of the body, such as the arm or leg. Strokes in children can affect the emotional state of a child, but early diagnosis and treatment will increase the chances of a full recovery.

Almost 80% of all strokes result from the blockage of a blood vessel supplying the brain. These blockages can occur due to a leaky or burst blood vessel. These blockages in the blood vessels will damage the nerve cells in the brain, which will ultimately result in a stroke. Once a person suffers from a stroke, they will be unable to control their body. This is why they must get immediate medical care.

There are many causes of stroke. The most common of these is a ruptured blood vessel in the brain. It may be a small artery that ruptures. This can result in a severe stroke. A small tear can cause a blood clot to form, and it may block a major artery or narrow the arteries in the brain. If you notice these symptoms in someone, you should seek medical attention as soon as possible.

There are two types of stroke. Ischemic stroke is the most common type of stroke. It occurs when a blood clot blocks an artery in the brain. It can also be caused by a buildup of cholesterol or fatty deposits, known as plaque. Another type of stroke is called hemorrhagic. It happens when a blood vessel bursts in the brain, causing excessive pressure on the nearby brain tissue.

When blood flow is disrupted, neurons begin to die and permanent brain damage results.

In addition to the underlying cause of the stroke, a person's physical symptoms can indicate the onset of a clot. To make sure that the patient has the appropriate medications to prevent further damage, they will undergo a series of tests. The first step is a blood test. A complete blood count will show whether there are any bleeding or abnormalities. Other tests may be performed, including a noncontrast CT scan. If a stroke is suspected, doctors will assess the symptoms and prescribe medications.

If you can lower your blood pressure, you will drastically lower your chances of having a stroke.
