Brain stroke: Warning signs and recognition
Article by Doctor of General Surgery, Vinmec Central Park International General Hospital.
Brain stroke is a condition in which blood flow to a part of the brain suddenly decreases or stops, which leads to a decrease in oxygen and nutrients in the brain parenchyma, causing brain cells to die within minutes.
1. What is a brain stroke?
Brain stroke is one of the top 3 causes of death and disability in countries, early detection and recognition of stroke has the ability to restore nerve function and reduce sequelae.
Brain stroke can be in the form of cerebral infarction or cerebral hemorrhage. In some cases, temporary but reversible ischemia does not lead to a severe condition known as transient ischemic attack.
2. How to recognize a stroke?
In the case of a stroke, the word FAST can be used to remember the warning signs:
Face : face distorted on one side, more visible when the patient opens his mouth wide or tries to smile. Arm (hand): one hand is weak, the two hands are uneven. Speech (speech): speaking unclear words, stammering, or speaking difficult, unable to express what you want to say. Time: the time to treat the stroke as soon as possible, calculated in seconds, minute by minute. When you have the above signs, you should be transferred to the nearest hospital as soon as possible.
3. Is brain stroke treatable?
Depending on the duration and type of stroke, it can be fully reversible, partially reversible, or life-threatening. In general, early detection and treatment are less likely to leave sequelae and limit life-threatening.
For cases of transient ischemic attack, screening and detection of risks can be treated and fully recovered.
4. Can a brain stroke be prevented?
Screening and prevention of risk factors can reduce stroke by up to 90%. Local factors include: atherosclerosis, narrowing of the great arteries: carotid artery, vertebral artery, vascular dissection. Other factors include: atrial fibrillation, valvular disease, heart failure, arrhythmias, and hypotension. Systemic diseases: diabetes, vascular disease. Based on the duration of cerebral ischemia, the patient's age and related diseases, doctors can determine the probability of stroke and plan effective preventive measures.

In which, Magnetic Resonance Imaging - MRI/MRA is considered a "golden" tool for brain stroke screening. MRI is used to check the condition of most organs in the body, especially valuable in detailed imaging of the brain or spinal nerves. Due to the good contrast and resolution, MRI images allow to detect abnormalities hidden behind bone layers that are difficult to recognize with other imaging methods. MRI can give more accurate results than X-ray techniques (except for DSA angiography) in diagnosing brain diseases, cardiovascular diseases, strokes,... Moreover, the process MRI scans do not cause side effects like X-rays or computed tomography (CT) scans.\
