Predict Brain Stroke

Only 12-15% of patients with transient ischemic symptoms are considered a warning sign of a stroke, while most have no symptoms before the stroke occurred.
The causes of stroke are therefore considered to be explosive bombs, when they explode, they leave unpredictable consequences.
The detection and preventive treatment before a stroke is extremely necessary and important, helping patients to avoid stroke.
Tracing the factors leading to brain stroke
Brain stroke is a clinical syndrome characterized by acute loss of brain function, existing beyond 24 hours or dying before 24 hours.
Localized neurological symptoms are appropriate for the area of the brain where the arteries are distributed, not the cause of injury

. Stroke is also known as a stroke.
A stroke or stroke is a disease caused by damage to a blood vessel in the brain. According to the international classification, cerebrovascular disease has two main types: cerebral infarction and cerebral bleeding
A cerebral infarction or ischemic is caused by a blocked, blocked or narrowed brain vascular (accounting for the majority of 87%).



Brain bleeding is caused by a broken brain blood vessel, usually where the artery is an aneurysm (3%), a deformed blood vessel or a bleeding clotting disorder.
- The cause of the blockage or thrombosis is usually due to atherosclerosis or inflammation, formation of atherosclerotic plaques and blood clots that gradually narrow the artery.
If the vessel is very narrow (when it is ≥ 75% stenosis), it will show the anemia in the posterior brain due to that blood supply, when the brain blood flow is less than 10ml / 100g brain / minute will cause infarction (normal). The average brain flow in adults is 49.8ml ± 5.4ml / 100g brain / minute).
- Cerebral embolism is caused by a clot from another location of the lumen that moves It can be from the heart or the artery, from the aorta to the carotid artery, and onto the cerebrovascular arteries, it will stop in the smaller artery and cause a loss of blood supply to the brain due to the artery.



which governs, thereby causing cerebral infarction.
A heart blockage is often caused by blood clots in the heart due to mitral stenosis, atrial fibrillation and arrhythmia. Arteries that form in the vessels are usually plaque that bursts up and flows upward along the flow of the brain's circulation.
- Artery narrowing due to cerebrovascular spasm, common in subarachnoid bleeding, after migraine, acute hypertension, vascular intervention.
- Brain bleeding can be caused by hypertension, caused by rupture of brain aneurysm or congenital artery malformation (AVM), epidural rupture rupture or hemostatic disorders.
Cerebral aneurysms can be congenital, may be caused by damage to a vessel wall and hypertension.
So what should be done to anticipate the possibility of a stroke?
To know in advance this is no other way to know the vascular system of the brain, the vascular system from the heart to the brain as well as the clotting factors in the body.
For young people, the likelihood of having a stroke is due to congenital cerebral artery malformation, congenital brain artery aneurysm; cerebral embolism due to complications of mitral valve stenosis causing atrial fibrillation, formation of circulatory blood in the heart to the brain or blood diseases such as thrombocytopenic purpura, dengue fever.




So the first thing to do is to have regular checkups for blood diseases, check your heart for heart valve disease?
For children with headaches, seizures, epilepsy, cognitive impairment, should be checked for cerebrovascular blood by magnetic resonance imaging of brain vessels or computed tomography. When in doubt, remove background-digitized digital angiography (DSA) to identify lesions.
For people with high risk factors such as hypertension, diabetes, obesity, dyslipidemia, cardiovascular disease, atherosclerosis, transient ischemic attack, alcoholism, tobacco addiction ... it is important to examine the brain vascular system, carotid system, aorta and heart.
Determining whether the brain blood vessels are swollen, deformed, narrowed or have blood clots in the heart? Patients need an electrocardiogram, echocardiography, aortic and carotid artery ultrasound and it is best to capture the brain vascular system using magnetic resonance imaging or CT scans.
For people over 55, this is the group most likely to have a stroke, mainly due to thrombotic cerebral infarction or cerebral haemorrhage due to rupture of aneurysms or hypertension.



It is necessary to carefully examine the carotid artery system, the brain artery system by ultrasound and magnetic resonance angiography, CT scan or angiogram to take blood vessels of brain DSA.
How to prevent a stroke? Who can be a stroke?
Stroke does not exclude age and gender, but stroke increases with age; for every decade after age 55, the risk of stroke increases by two times.
Risk factors for stroke include hypertension (60-75%), atherosclerosis (35%), heart valve disease (12-15%), diabetes (15-25%), confusion dyslipidemia (40-57%), tobacco addiction (30-35%), alcoholism (25-30%), obesity, transient anemia (15%) ...
The death rate from stroke is second (9%) after cancer worldwide, and third after cancer and cardiovascular disease in the US. The death rate from brain stroke in Vietnam accounts for 1.
