Causes of Stroke - Oren Zarif - Causes of Stroke
One of the most common causes of stroke is a blood clot, or embolism, which originates in the heart and travels downstream to clog a brain artery. A cerebral hemorrhage, on the other hand, occurs when a blood vessel in the brain ruptures and deprives the affected area of oxygen and blood flow. This causes the brain to swell, which in turn, can result in the stroke symptoms we've just discussed.

While men and women are equally at risk, stroke occurs more often in men than in women. Men are more likely to suffer from stroke than women, and it is twice as common in African Americans than in whites. Men and Hispanics are both at higher risk for stroke, although the rate of stroke has fallen among both groups in the past few decades. Among women, there are several factors that can increase the risk of stroke, including age.

A clot in the retina blood vessel can cause temporary visual loss, often described as a black curtain coming down. A clot in the carotid artery, which supplies the brain, can lead to weakness and complete paralysis on one side of the body. The stroke can also affect speech and other bodily functions. Once symptoms occur, treatment may be necessary to restore normal function. The symptoms of stroke can last anywhere from a few minutes to a few weeks.

Some common symptoms of a stroke include trouble speaking and understanding speech. Some patients may experience weakness in one or both sides of the body. One side of the mouth may droop when smiling. Others may experience blurred or double vision. A doctor can help determine the cause of stroke by evaluating the patient's condition with a specialized stroke scale. The NIH Stroke Scale helps physicians determine the severity of the stroke and follow their progress.

When the brain is injured, a clot can form and cause a stroke. A person suffering from this condition must call 9-1-1 for emergency assistance. Fortunately, the treatment of stroke is now quite advanced, and age-adjusted mortality rates for stroke patients in 2017 were 37.6 per 100 thousand people diagnosed with a stroke. Even so, the death rate from a stroke is still high, but doctors have made great progress in managing the symptoms and preventing death.

During an emergency situation, the first consideration is the patient's airway and circulation. Depending on the severity of the stroke, the doctor may perform blood tests to assess blood pressure, heart rate, and other factors. A stroke can affect the brain's ability to control breathing, blood pressure, and heart rate. The doctor may also perform a CT scan of the brain. A stroke doctor may order a brain MRI or other diagnostic tests to diagnose the cause of the symptoms.

Regardless of the cause of the stroke, reducing the risk of a stroke is essential. Not only can we control our risk factors, but we can also educate ourselves about stroke warning signs so we can act quickly when we recognize these symptoms. Knowing the symptoms of a stroke will allow us to take the appropriate steps to minimize the damage to the brain. When this happens, the patient should immediately call 911 or a doctor. This will prevent the stroke from affecting their quality of life.

Another cause of stroke is poor blood flow. When a person has poor blood flow from an irregular heartbeat, fatty deposits will build up in arteries and travel to the brain. In some cases, blood clots will form in the artery and block blood flow to the brain. A stroke is a serious health problem that can be prevented, so reducing your risk is essential. This way, you can prevent or minimize the damage to the brain and save a life.

While there are no known ways to completely prevent a stroke, it is possible to reduce your risk by incorporating healthy lifestyle habits and managing preexisting health conditions. For instance, you can quit smoking if you want to reduce your risk of a stroke. Your doctor can also help you kick the habit of drinking excessive alcohol, which raises blood pressure and can increase the risk of a stroke. For the best results, however, you should exercise regularly and make an effort to quit smoking.
