What Causes Stroke? - Oren Zarif - Causes of Stroke

If you're wondering what causes stroke, you've come to the right place. Here are several major risk factors. A person with atrial fibrillation is at a high risk of having a stroke. If you have this condition, call 911 right away. Despite the name, ischemic stroke can be life threatening and require immediate medical attention. A mini-stroke is caused by bleeding into the brain tissue, while an ischemic stroke can result in transient or permanent loss of function.

When a stroke starts, the brain cells die due to lack of blood. Transient ischemic attack (TIA) symptoms are similar to stroke, and can occur at any time. The symptoms include weakness, numbness, facial droop, and difficulty swallowing. These symptoms often last for minutes or even hours, and can be a warning sign of a more severe stroke. The first step in treating a stroke is to identify the symptoms of TIA.

If you or a loved one is experiencing stroke symptoms, visit a hospital as soon as possible. Emergency room doctors will likely give you fluids and oxygen, and may also perform a CT scan or an MRI. A CT scan or MRI of the brain will be the most important imaging tests. Depending on the severity of the stroke, your doctor may recommend thrombolytic therapy or other procedures to remove the clot. Once the cause of TIA is identified, you will be treated accordingly.

Hemorrhagic stroke, on the other hand, is caused by a ruptured artery in the brain. In hemorrhagic stroke, blood spills into part of the brain, causing excess pressure on the brain and swelling of the brain tissue. Because a healthy brain maintains a proper blood flow to the brain, a rupture in a vascular network will disrupt this blood flow, disrupting the chemical balance in the brain.

The speech center is located in the left half of the brain, so if a stroke strikes this side, you may experience trouble speaking. If a stroke affects your right side, you may experience weakness in your right arm, leg, or even combination of these areas. While the exact cause of your stroke is unknown, early treatment will help limit damage and restore function to the brain. When you notice the symptoms of a stroke, it is time to consult with a doctor. You should not hesitate to contact a hospital or emergency department to receive a diagnosis.

There are several risk factors for stroke. For example, people from certain ethnic groups are at a higher risk than others. In fact, African Americans are twice as likely to experience a stroke than any other ethnic group. This is largely due to the fact that they experience a higher incidence of stroke than Caucasians and Hispanics. Those with sickle cell disease are at a higher risk than Caucasians. In addition, people with certain conditions like cancer or sickle cell disease are at a higher risk of having a stroke than those without.

Blood tests are another way to diagnose a stroke. A complete blood count will tell the doctor if the brain has suffered damage from bleeding or other conditions. An electrocardiogram will measure the electrical activity of the heart and can detect any heart conditions that led to a stroke. The other test, called a cerebral angiogram, looks at the neck arteries and clots. The results of these tests will help your doctor determine the best treatment options.

Another major risk factor is a blood clot in the brain. A clot in the retina blood vessel can cause temporary loss of vision. In some cases, a clot will travel downstream to clog a small artery in the brain. In some instances, a blood clot can also cause a brain hemorrhage, which can result in swelling and a variety of symptoms. If you have a history of head injuries, you can also influence your risk for stroke by modifying your lifestyle and reducing the number of alcohol and caffeine intake.

The risk for a stroke is higher for people who have heart conditions. Some of the most common heart conditions that increase the risk for a stroke include atrial fibrillation, patent foramen ovale, and heart valve disease. A number of other conditions can also increase your risk for a stroke, including illicit drugs, ruptured aneurysms, and even inherited predispositions to abnormal blood clotting.
