Stroke symptoms causes types prevention

 

Stroke occurs when the blood supply to part of the brain is interrupted or reduced, which prevents the flow of oxygen and nutrients into the brain tissue. The USA Best Doctors provide the facilities in USA.  As a result, brain cells begin to die within minutes. Stroke requires immediate medical attention, and immediate treatment for this disease is extremely important. Early action to prevent the effects of stroke reduces the likelihood of brain damage and prevents other complications. Effective treatment also helps prevent disability from stroke. 

Symptoms of stroke

If you or someone close to you suspects a stroke, pay special attention to the time of onset of symptoms. Some treatment options are most effective if administered shortly after the onset of stroke.

Signs and symptoms of stroke are:

Problems speaking and understanding what others are saying. You may confuse words, stop understanding them, or have difficulty understanding other people's language.

You may have sudden numbness, weakness or paralysis of the limbs, face. Often, a stroke affects only one side of the body. Try to raise both hands above your head at the same time (or ask someone you suspect to have a stroke). If one arm begins to fall, the person may have a stroke. In addition, one side of the mouth may hang down and not move if you ask the patient to smile.

Vision problems in one or both eyes. Blurred or darkened vision in one or both eyes may suddenly appear, as well as a double vision of what the person sees in front of them.

Problems with walking. The person may stumble or lose balance. Sudden dizziness or loss of coordination may also occur.

When to see a doctor?

You should see a doctor immediately if you notice any signs or symptoms of a stroke, even if they are completely gone. In this case, you need to conduct a rapid stroke test:

Causes of stroke

There are two main causes of stroke: clogged arteries (ischemic stroke) or rupture of a blood vessel (hemorrhagic stroke). Some people may have only a temporary disturbance in blood flow to the brain, known as a transient ischemic attack (TIA), which does not cause long-term symptoms.

Ischemic stroke

This is the most common type of stroke. This occurs when the blood vessels in the brain narrow or become blocked, leading to a severe reduction in blood flow (ischemia). Blocked or narrowed blood vessels are usually filled with fat, blood clots or other particles that pass through the bloodstream and settle in the course of movement. Currently, some studies suggest that COVID-19 may be a possible cause of ischemic stroke, but it is difficult to say for sure because more research is needed.

Haemorrhagic stroke

Haemorrhagic stroke occurs when a blood vessel in the brain ruptures or a micro-hole is formed in it. Haemorrhages in the brain occur as a result of various diseases that affect blood vessels. Factors associated with haemorrhagic stroke are:

·         Uncontrolled high blood pressure.

·         Excessive treatment with anticoagulants.

·         Convexities in weak places of walls of blood vessels (aneurysms).

·         Injury (e.g car accident).

·         Deposition of protein in the walls of blood vessels, which leads to weakness of the vessel wall (cerebral amyloid antipathy).

·         Ischemic stroke that leads to bleeding.

·         A less common cause of cerebral haemorrhage is a rupture of an abnormal tangle of thin-walled blood vessels (arteriovenous malformation).

Transient ischemic attack (TIA)

Transient ischemic attack (TIA) - sometimes called a mini-stroke - is a temporary period of symptoms that are similar to those seen in a stroke. TIA causes irreparable damage to the brain. It is caused by a temporary decrease in blood supply to the brain, which lasts up to several minutes.

Like ischemic stroke, TIA occurs when a blood clot or foreign particles reduce or block blood flow. It is not possible to determine whether a patient has a stroke or TIA based on symptoms alone. If you have had a TIA, this means that you may have a partially blocked or narrowed artery that leads to the brain. If a person has had a TIA, they are at increased risk of having a full-blown stroke over time.

Stroke prevention

Knowing the risk factors for stroke, following your doctor's advice, and living a healthy lifestyle are the best prevention measures you can take to prevent a stroke. The best doctors in USA provide the facilities in USA. If you have had a stroke or transient ischemic attack (TIA), these preventative measures will be helpful:

·         Control of high blood pressure (hypertension).

·         Smoking cessation.

·         Maintaining normal blood sugar levels.

·         Maintain a healthy weight.

·         Eating lots of vegetables and fruits, a balanced diet.

·         Regular sports, walking, exercise;

·         Minimize alcohol consumption.

·         Treatment of obstructive sleep pane.
