Do you suddenly experience weakness or paralysis on one side of your face, arm, or leg? Is your mouth drooping when you smile? Do you have difficulty speaking or slurred speech? Do you have a severe headache with no clear cause? These could be four warning signs of a stroke. Time is a critical factor in stroke treatment. Early recognition of these signs gives you or your loved ones the opportunity to receive timely emergency care, minimizing brain damage and increasing the chances of recovery. Read on to understand the importance of recognizing these four dangerous signs. If you suspect a stroke, contact emergency medical services immediately.
What is a Stroke?
Cerebrovascular accident, also known as a stroke, is a dangerous neurological condition and a medical emergency. It is a serious health event that occurs due to a sudden interruption of blood supply to the brain. This interruption leads to a lack of oxygen and nutrients for brain cells, causing brain damage. This damage can result in permanent brain damage, disability, or death.
Cerebral Ischemia (Ischemic Stroke)
Cerebral ischemia, or ischemic stroke, is a type of stroke that occurs when a blood vessel supplying blood to the brain becomes blocked. This blockage is often caused by a blood clot forming within the vessel (thrombosis) or by a blood clot traveling from elsewhere (embolism). As a result, a part of the brain does not receive enough oxygen and nutrients, leading to nerve cell damage. Signs of cerebral ischemia typically appear suddenly and are clear, including: weakness or paralysis on one side of the face, facial drooping, difficulty speaking, severe headache, dizziness, vision impairment, sensory disturbances, difficulty swallowing, personality changes, and even seizures.
These signs require serious attention, as this is a medical emergency that demands immediate medical intervention.
Cerebral Hemorrhage
Cerebral hemorrhage is a type of stroke that occurs when a blood vessel in the brain ruptures, causing bleeding into the brain tissue. High blood pressure is the main cause of cerebral hemorrhage. The spilled blood creates pressure on brain cells, leading to tissue damage and symptoms similar to cerebral ischemia: weakness or paralysis, facial drooping, difficulty speaking, severe headache, dizziness, vision impairment, sensory disturbances, difficulty swallowing, and personality changes. However, in cerebral hemorrhage, a sudden and very severe headache often occurs. Emergency care and treatment for cerebral hemorrhage require urgent medical intervention at a hospital. Treatment methods may include surgery to remove the blood clot or medication to control blood pressure. CT/MRI scans of the brain are crucial diagnostic imaging methods to determine the location and extent of bleeding. Similar to cerebral ischemia, rehabilitation is an important part of the treatment and recovery process for patients.
Recognizing 4 Stroke Warning Signs at Home
A stroke occurs due to a sudden interruption of blood supply to the brain, which can be caused by a blood vessel blockage (ischemic stroke) or a ruptured blood vessel (hemorrhagic stroke). The warning signs often appear suddenly and are clear. Remember the FAST method for easy recognition:
F – Face: Weakness or paralysis on one side of the face. Ask the person suspected of having a stroke to smile. If one side of their mouth droops, is difficult to lift, or they drool, it’s an alarming sign. This is a very easily recognizable and undeniable sign.
A – Arms: Weakness, numbness, or paralysis on one side of the arm. Ask the person to raise both arms. If one arm is weaker or cannot be raised, or feels numb, be vigilant.
S – Speech: Difficulty speaking, slurred, or incomprehensible speech. Ask the person a simple question. If they speak with difficulty, stammer, or cannot speak clearly, this is an important sign of a stroke.
T – Time: If you notice any of these signs, call emergency services immediately. Time is a critical factor in stroke treatment. The sooner intervention occurs, the higher the chance of recovery. Don’t hesitate, call 115 (or your local emergency number) or take the patient to the nearest hospital.
Early detection of stroke signs increases the chance of recovery. Timely treatment can minimize brain damage. After noticing the above signs, follow these steps:
Call emergency services (115): This is the most important step. Inform medical staff about the patient’s condition and your address.
Keep the patient still: Place the patient on their side to prevent choking if they vomit. Do not give them anything to eat or drink.
Record the time symptoms appeared: This information is crucial for doctors to develop an effective treatment plan.
Take the patient to the hospital: If possible, take the patient to a hospital with a specialized stroke unit as soon as possible. Time is critical for stroke patients.
Stages of Stroke
Initial Stage
The initial stage of stroke (CVA) often progresses very rapidly, with symptoms appearing suddenly. This is the most critical time, determining the success of the treatment and recovery process. You need to be alert to recognize the warning signs, which typically include:
Sudden weakness or paralysis: A feeling of weakness or paralysis on one side of the face, arm, or leg. Try to raise both arms; if one arm is weak or drops, it could be a sign of CVA.
Facial drooping: Difficulty smiling or making facial movements, with one side of the mouth drooping.
Difficulty speaking: Difficulty talking, slurred speech, unclear speech, or inability to speak. Try saying a simple sentence; if you have difficulty, seek immediate medical help.
Severe headache: Sudden, severe headache, unusual compared to typical headaches. This is often a sign of cerebral hemorrhage.
Dizziness, loss of balance: Severe dizziness, difficulty maintaining balance, or sudden falls.
Vision impairment: Sudden blurred vision, double vision, or partial or complete loss of vision.
Sensory disturbances: Numbness, tingling on one side of the body.
Difficulty swallowing: Difficulty swallowing food or drink.
Personality changes: Sudden personality changes, becoming irritable, anxious, or confused.
Seizures: In rare cases, seizures can be a sign of CVA.
If you or a loved one experiences any of these signs, call emergency services immediately (115 or your local emergency number). Time is a critical factor.
Crucial Stage
The crucial stage is when the patient is brought to the hospital and undergoes emergency treatment. Doctors will perform necessary tests such as CT/MRI scans to determine the type of stroke (ischemic or hemorrhagic) and the extent of brain damage. Timely and accurate treatment is key to minimizing brain damage and improving the chances of recovery. Treatment methods may include:
Medication: Thrombolytic drugs (tPA) are used to dissolve blood clots in cases of ischemic stroke. However, this medication is only effective within a specific time window.
Surgery: In cases of cerebral hemorrhage, surgery may be performed to remove blood clots or reduce pressure on the brain.
Progressive Stage
The progressive stage focuses on rehabilitation and long-term disease management. This process can last for months or years, depending on the severity of the stroke and the patient’s response to treatment. Rehabilitation includes:
Physical therapy: Helps restore motor function, strengthen muscles, and improve motor coordination.
Speech therapy: Helps improve communication and swallowing abilities.
Occupational therapy: Helps patients adapt to daily life and perform routine activities.
Additionally, adhering to the doctor’s treatment plan, maintaining a healthy lifestyle, a balanced diet, and controlling risk factors such as high blood pressure, diabetes, and cardiovascular disease are crucial to ensuring the best possible health and quality of life.
Can a Mild Stroke Heal on Its Own?
A mild stroke does not mean it’s not dangerous. Although symptoms may be milder than a severe stroke, it is still a serious health event that requires monitoring and treatment. Problems with cerebral blood circulation can cause potential damage, affecting long-term health. Do not be complacent and assume the condition will heal on its own.
Early recognition of stroke signs is the first and most important step. Remember the FAST principle:
Face: Facial drooping, difficulty smiling on one side of the face.
Arms: Weakness or numbness on one side of the arm.
Speech: Difficulty speaking, incomprehensible speech, or slurred speech.
Time: Call emergency services immediately if any of the above signs appear.
In addition, some other signs of a mild stroke may include:
Sudden, severe headache.
Dizziness, loss of balance.
Vision impairment, blurred or double vision.
Sensory disturbances, numbness, tingling.
Difficulty swallowing.
Personality changes, confusion, short-term memory loss.
Seizures (in some cases).
If you or a loved one experiences any of these symptoms, however mild, seek immediate medical attention. The golden hour for intervention and treatment is crucial. Do not wait to see if the situation improves.
What Causes Stroke and How Can It Be Effectively Prevented?
Some key risk factors contributing to stroke include:
High blood pressure: This is the main cause of cerebral hemorrhage. High blood pressure damages blood vessel walls, making them prone to rupture.
Cardiovascular disease: Conditions such as coronary artery disease, atrial fibrillation, and high cholesterol increase the risk of blood clot formation, leading to ischemic stroke.
Diabetes: Diabetes damages small blood vessels, increasing the risk of stroke.
Smoking: Smoking increases the risk of blood clot formation and raises blood pressure.
Physical inactivity: Lack of exercise increases the risk of obesity, high blood pressure, and cardiovascular diseases.
Older age: The risk of stroke increases with age, especially in people over 65.
Family history: If a family member has had a stroke, your risk of developing the condition will be higher.
Dyslipidemia: High cholesterol levels in the blood increase the risk of plaque formation in blood vessels.
Preventing stroke is a long-term process that requires perseverance and lifestyle changes. Here are specific steps you need to take:
Control blood pressure: Regularly monitor blood pressure and take medication as prescribed by your doctor if necessary.
Manage diabetes: If you have diabetes, work closely with your doctor to control your blood sugar levels.
Quit smoking: Smoking is a major risk factor for stroke; be determined to quit.
Eat a healthy diet: A diet rich in fruits, vegetables, whole grains, lean meats, and low in saturated fats, salt, and sugar.
Exercise regularly: At least 30 minutes of physical activity daily, 5 days/week. Choose activities appropriate for your physical condition.
Lose weight if needed: If you are overweight or obese, losing weight can help reduce the risk of stroke.
Regular health check-ups: Regularly visit your doctor for health check-ups to detect cardiovascular and cerebrovascular diseases early.
Stay hydrated: Water helps maintain good blood circulation.
Manage stress: Chronic stress can affect cardiovascular health.
Get enough sleep: Lack of sleep increases the risk of many diseases, including stroke.
Diet and Lifestyle After a Stroke
Diet plays a pivotal role in the recovery process after a stroke. A balanced, nutrient-rich diet will support the brain in repairing and restoring function. You need to focus on the following factors:
Limit salt: Reducing salt intake helps control blood pressure, a significant risk factor for cerebrovascular disease. Use alternative seasonings such as pepper, onion, and garlic to enhance the flavor of dishes.
Increase fiber intake: Fiber found in fruits and vegetables helps regulate blood sugar and cholesterol, supports cardiovascular health, and reduces the risk of stroke recurrence. Eat plenty of green vegetables and fresh fruits daily.
Supplement good fats: Monounsaturated and polyunsaturated fats found in salmon, avocados, and various nuts help protect heart and brain health.
Adequate protein: Protein is a building block for cells, helping to repair tissue damage. Eat lean meats, fish, eggs, and soybeans.
Drink enough water: Water helps maintain the function of body organs and helps the kidneys eliminate toxins. Drink 2-3 liters of water daily.
Limit sugar: Sugar increases the risk of diabetes, a risk factor for stroke. Limit sweets and sugary carbonated drinks.
Expert consultation: Consult a doctor or nutritionist for personalized dietary advice suitable for your specific health condition. They will help you create a customized meal plan to optimize the recovery process.

Frequently Asked Questions About Stroke
Can One Have Sexual Intercourse After a Stroke?
The answer is not a simple “yes” or “no”. The ability to have sexual intercourse after a stroke depends entirely on the patient’s health status, the extent of recovery, and the doctor’s advice. A stroke can affect cardiovascular health, causing problems with blood circulation, increasing the risk of heart attack or recurrent stroke. Therefore, sexual intercourse, an activity that requires physical and psychological effort, needs to be carefully considered.
After experiencing a stroke, some patients suffer from weakness, paralysis, and difficulty moving, affecting their mobility and making sexual intercourse challenging. These patients need to consult their doctor for a comprehensive assessment of their health status and specific guidance.
Is Stroke Dangerous?
A stroke is a dangerous neurological condition, a medical emergency that can lead to permanent brain damage, disability, or death. The sudden interruption of blood supply to the brain causes severe damage to brain cells. Depending on the location and extent of the damage, patients may experience weakness or paralysis, facial drooping, difficulty speaking, severe headache, dizziness, vision impairment, sensory disturbances, difficulty swallowing, and even seizures. The risk of death is high, especially in cases that are not treated promptly or where brain damage is extensive. The golden hour for intervention and treatment is crucial; the sooner emergency care and treatment are provided, the higher the chances of recovery.
Should Acupuncture Be Used for Stroke?
Currently, there is insufficient scientific evidence to fully prove the effectiveness of acupuncture in treating stroke. Although some people believe that acupuncture can help improve certain symptoms, such as pain reduction or improved blood circulation, this needs further research. More importantly, acupuncture cannot replace mainstream medical treatments such as medication, rehabilitation, or surgery.
Is ‘Tai biến’ a Stroke?
Yes, ‘tai biến mạch máu não’ (cerebrovascular accident) and ‘đột quỵ’ (stroke) are two terms often used interchangeably. Both refer to the same phenomenon: a sudden interruption of blood supply to the brain, leading to brain damage. Ischemic stroke and hemorrhagic stroke are all forms of cerebrovascular accident (tai biến mạch máu não).
Where to Get Examined and Treated for a Stroke?
Major hospitals in Vietnam and specialized stroke centers are fully equipped with facilities and experienced medical teams to handle stroke cases. Seek information about reputable hospitals near you to receive the best support. You can also find information on the website of the Ministry of Health or other trusted medical organizations.
