A visual guide to understanding stroke
1. What is a stroke?
2. Symptoms of a stroke
Numbness or muscle weakness, especially often on one side of the body Vision changes in one or both eyes Difficulty swallowing Severe headaches with no known cause Dizziness, walking Difficulty, difficulty moving Slurred speech, difficulty speaking, numb tongue Memory disorder Symptoms that signal a stroke do not last long, so when you see abnormal symptoms, you should not be subjective, should get emergency care promptly. .
In order to recognize the risk of stroke early, many countries are now using the "FAST" rule:
Face: face is asymmetrical or one side of the mouth is distorted, can ask the patient to smile to see Arm better. : the patient will raise both hands, whichever side is weaker or falls first, that side has paralysis Speech: abnormality in language, the patient will be asked to repeat a simple sentence. If the voice is not round, clear, not fluent or can not speak, this is a sign of abnormality Time: The patient is at very high risk of having a stroke if all three of the above signs occur. It is necessary to urgently bring the patient to a medical facility for treatment.
3. Stroke diagnosis
Once the brain stops working, the parts of the body controlled by the brain will also stop working. Therefore, stroke is the leading cause of long-term disability in patients.
To diagnose a stroke, doctors will perform a blood test to check the growth of the clot or the extent of the bleeding.
Besides, CT scans can help doctors understand the symptoms of stroke caused by hemorrhagic or blood clots.
Several other tests may be done to find out where the blood clots or where the bleeding is in the brain.
4. Types of stroke
The following are some common types of stroke, including:
Ischemic stroke : This is the most common type of stroke, accounting for up to 90%. An ischemic stroke occurs when an artery in the brain is narrowed or blocked, causing blood to flow less or less. Hemorrhagic stroke: This type of stroke is less common but has a high chance of death. A hemorrhagic stroke occurs when a blood vessel in the brain bursts or leaks, making it difficult for the bleeding to stop. Blood flow to the brain is temporarily blocked, causing stroke-like symptoms. When blood flow returns to normal, stroke symptoms should go away. It can also be a sign of an impending major stroke.
5. Causes of stroke
A blockage of a blood vessel in the brain can occur due to a blood clot. It causes ischemic stroke. Atherosclerosis makes it easier for blood clots to form.
Hemorrhagic stroke can occur if uncontrolled high blood pressure leads to a ruptured artery.
6. Risk factors for stroke
Heart rhythm disorders High blood pressure High cholesterol Diabetes Obesity Besides, some habits can make you more likely to have a stroke such as: :
Smoking Do not exercise Drinking alcohol If you eat too much fat and cholesterol can cause the arteries to be narrowed by high cholesterol, increasing the risk of blood clots in the walls of blood vessels, obstructing the blood flow. circulation to the brain. A diet rich in fruits, whole grains, and fish may help reduce the risk of stroke.
In addition, some other factors such as age, genetic factors also increase the risk of stroke. Men are more likely to have a stroke than women, but women are more likely to die from a stroke.
7. Stroke treatment
For hemorrhagic stroke, depending on the bleeding or hematoma, the doctor will prescribe appropriate treatment. Treatment usually tries to control high blood pressure and bleeding in the brain.
Whether a stroke causes long-term damage to the patient depends on the severity of the disease and whether the patient is treated promptly or not.
A stroke survivor may experience one or more health problems, such as numbness in the arms or legs and difficulty walking, vision, swallowing, speaking or understanding. These problems can be permanent, but in many cases people recover some or even most of their abilities.
8. Stroke recovery
Speech function : Rehabilitation is key to the stroke recovery process. It helps people regain lost skills and learn to adapt to those vulnerabilities. The goal is to help restore as much as possible. For people who have difficulty speaking, speech therapists can help people talk more coherently, more clearly Motor function: Problems with movement or balance are common. out after a patient has had a stroke. This can affect the person's daily activities. Physical therapy is an effective way to regain muscle strength, balance, and coordination. Sensory function: After a stroke, some patients' thoughts and feelings change in a negative direction such as fear, anger, anxiety... even depression. You should talk to a psychologist to learn how to manage your own emotions.
9. Stroke prevention
Don't smoke Exercise Exercise Exercise regularly Limit alcohol Don't eat salty foods A healthy diet with lots of vegetables, fish and whole grains For people at high risk of stroke, doctors often recommend medication to reduce this risk. Medicines including aspirin prevent blood clots from forming. Some people may need anticoagulants, such as warfarin. And if you have high blood pressure or high cholesterol levels, your doctor will prescribe medication to lower them, in conjunction with lifestyle changes.
In some cases of carotid artery stenosis, people who have had a mild stroke due to this problem may be offered carotid endarterectomy to remove plaque from the lining of the carotid artery. carotid artery and may prevent additional strokes. Your doctor will help you weigh the risks and benefits of this method.
Besides, doctors can treat blocked carotid arteries without surgery with a procedure called angioplasty and stenting to open up the artery.
More than half of people who have a stroke regain the ability to care for themselves. Patients who have had a stroke can be fully recovered if they are given blood-clotting drugs early. Although the risk of a second stroke is higher than at first, this risk decreases over time.
