Mild stroke also known as mini-stroke or transient ischemic attack. This is a condition in which blood stops flowing to the brain for a short period of time. According to some statistics, after experiencing a mild stroke, up to 50% of patients have at least one stroke within 5 years. Therefore, recognizing the symptoms of a mild stroke will help you prevent dangerous complications. What are the symptoms of a mild stroke?
1. What is a mild stroke?
Mild stroke also known as mini-stroke or transient ischemic attack. However, a mild stroke does not kill brain cells as in a real stroke. Mild strokes also cause stroke-like symptoms and are a warning sign of possible future strokes. Usually, mild strokes last less than 24 hours and last for only a few minutes or just 1-2 hours. Some studies show that up to 90% of cases of transient anemia resolve within 4 hours without causing any damage.
A temporary lack of blood supply to the brain is the main cause of this condition. A volume of blood to feed the brain and nervous system accounts for about 15% of the total blood volume of the whole body and is supplied to the brain by the contraction of the heart and the movement of the arterial system. When this amount of blood is deficient, it will affect the brain and many activities of the organs in the body. According to the American Heart Association, transient cerebral ischemia will reduce the life expectancy of patients by 20%. Approximately 10-15% of patients will have a true stroke within 3 months of experiencing a transient ischemic attack. 50% of these had a stroke within 48 hours of a minor stroke.

2. Symptoms of a mild stroke
A transient ischemic attack is difficult to identify. Some symptoms of a mild stroke include:
Sudden rise in blood pressure Weak muscles Numbness in the arms or legs Dizziness Sudden dizziness Unconsciousness Changes in consciousness Temporary memory loss Dull body tingling Changes Change in mood Difficulty in pronunciation Loss of balance Loss of vision or double vision In addition, some symptoms of a mild stroke can be confused with other conditions such as:
Migraine: headaches often accompany symptoms of nausea, fear of bright lights and sounds. Pain usually develops slowly over 30 minutes. Syncope: The patient has a sudden, brief loss of consciousness, without other symptoms. Transient seizures: symptoms usually begin in some parts and then gradually spread. Transient amnesia: the patient suddenly loses memory. When awake, the patient had no other focal neurological symptoms.
3. Causes of mild stroke
Risk factors that can lead to mild stroke include:
Family history: some of your family members have a history of mild stroke, you will be at higher risk. Age: The elderly, especially those over 55, are more likely to experience transient anemia. Gender: Men are more likely to have mild strokes than women. However, more than half of all mild stroke deaths are in women. Past stroke: People who have had a previous stroke are about 10 times more likely to have a recurrence. Sickle cell disease: also known as sickle cell anemia. Sickle blood cells carry very little oxygen. At the same time, this cell tends to get stuck in the artery wall. This will interfere with blood flow to the brain. High blood pressure is one of the most common causes of small strokes. High blood pressure is also the real cause of stroke, so a transient ischemic attack is a sign of a more serious condition in the future. Good blood pressure control is important in preventing future transient ischemic attack and stroke.

4. Diagnosis and treatment of mild stroke
4.1 Diagnosing a Mild Stroke Since the symptoms of a mild stroke are often difficult to recognize, the disease is often detected through accurate diagnoses. The methods of diagnosing transient stroke include:
Blood tests: to help detect dyslipidemia and the risk of atherosclerosis and stroke. Electrocardiogram: may be used in cases of atrial fibrillation or some other arrhythmia. Echocardiography: to detect valvular lesions and signs of cardiac dysfunction,... Ultrasound of the carotid and basal-vertebral arteries: helps to identify lesions of the intima-media layer arteries, atherosclerosis,... Cranial doppler ultrasound: helps to evaluate the circulation in the brain and cerebral arteries. Computed tomography or magnetic resonance imaging: helps rule out some related diseases, especially brain tumors or trauma,... 4.2 Treatment of minor strokes Mild strokes need to be treated like a stroke real stroke. Depending on the cause of the disease and the extent of the medical condition, the doctors can offer an appropriate treatment regimen including:
Some drugs to stabilize the underlying disease such as blood pressure, diabetes, blood fat, prevent thrombosis, ... to help treat anemia to nourish the brain. Maintain a healthy lifestyle and diet, quit smoking, lose weight and limit eating high-fat foods. If the lumen is narrowed more than 70%, intervention measures are needed on a case-by-case basis. In short, a mild stroke is also known as a mini-stroke or transient ischemic attack. This is a condition in which blood stops flowing to the brain for a short period of time. Recognizing the symptoms of a mild stroke will help you prevent dangerous complications. Therefore, when you see mild stroke symptoms such as high blood pressure, temporary memory loss, altered senses, dizziness, etc., it is necessary to immediately go to a medical facility to be examined by a doctor. and appropriate treatment regimen.
To screen for stroke, Vinmec doctors can prescribe brain MRI without injecting contrast, with 3D MRA TOF pulses, supplemented with Axial T2W and or axial FLAIR pulses for 7 minutes, helping to detect present brain aneurysm lesions, cerebral arteriovenous malformation, dural arteriovenous fistula, cerebral artery stenosis and some abnormalities in brain parenchyma. When there is an abnormality on the cerebral blood vessels, the doctor will order more magnetic contrast injection to investigate more cerebral vascular imaging (MRA). From there, there is an accurate assessment of the shape and size of the abnormality to give appropriate treatment indications.
The 3.0 Tesla MRI system at Vinmec hospitals across the country is equipped with state-of-the-art equipment by GE Healthcare (USA) with high image quality, allowing for a comprehensive assessment, not missing the damage but reducing the damage. shooting time. Silent technology helps to reduce noise, create comfort and reduce stress for customers during shooting, resulting in better image quality and shorter shooting time.
