Stroke: Identification signs and prevention

Cerebral vascular accident or stroke is becoming important issue of medicine because life expectancy is increasing and the risk of stroke depends on age . In particular , the disease is increased when the weather is cold . Each year , in our country , cerebral vascular accident is affecting hundreds of thousands of people and leave the serious sequelae

What is stroke ?

Brain stroke occurs when blood vessels that supply oxygen and nutrients to brain tissue that becomes blocked or bursts . When it happens , the nerve cells in the brain is paralyzed , do not work anymore . Therefore, part of your body they control are no longer in the same functions like before . There are many different causes of accidents but the most common is a clogged artery by a blood clot known as thrombosis , it is formed in the artery lumen . Or the arteries are due to atherosclerosis in the blood vessels and thickening fat accumulation . This gradually narrowing of the blood vessels , causing slow flow , to a point forming blood clots . A blood clot goes wandering entrained flow and muffled in a particular brain circuit called cerebral embolism . If an artery in the brain bursts causing bleeding, bleeding in the brain called cerebral hemorrhage. Cerebral hemorrhage can occur in patients with atherosclerosis and hypertension or occurs after a head injury or a congenital aneurysm rupture .
Blood clots cause embolism is a cause of cerebral vascular accident .

Who are susceptible to complications?
People who are infected are at risk for cerebral vascular accident :
- Patients with hypertension .
- People with cardiovascular diseases such as heart valve diseases , arrhythmias , atrial fibrillation , coronary artery diseases , heart failure , left ventricular hypertrophy …
- People with disorders of fat metabolism , increase blood cholesterol .
- People with diabetes .
- Complications caused by using drugs such as corticosteroids class of drugs , diuretics , birth control pills …
- People have a habit of smoking, drinking alcohol – beer , eating salty foods , overweight – obesity.

Some symptoms can signal a stroke:

- Sudden weakness , numbness face, hands and feet , facial palsy , hemiplegia or quadriplegia
- Sudden blurred vision , especially if one side of the face .
- Can not say a word or talk or do not understand other people saying.
- Having severe headache suddenlly .
- Dizziness, easy to fall , or drop off things.
- Can not move by themselves .
- Loss of consciousness.

Recognize early signs of cerebral stroke:
-Paralyzed extremities : the patient felt a hand or limb numbness , pain , tired body , saliva flowing , dizziness … few hours or a few days earlier . The most obvious manifestation of this is after waking up . This is a form of response by carotid system does not provide enough blood , brain ischemia , lack of oxygen .
-Suddenly dark face , can not see things : this phenomenon takes place in a few seconds or a few minutes and then recover normal vision . This proves retina is temporary anemia , the possibility of cerebral circulation is severely narrowed .
-Patients with inarticulate phenomenon : can not speak or difficult speaking or understanding others’ saying , sometimes messy thinking , no response , no answer … This is because the blood supply to the brain is missing , affects the language center of the brain cortex .
-Patients have phenomenon of dizziness , nausea , sometimes feel dizzy then suddenly fell unconscious . It is caused by arteries that supply blood to the brain is not fully enough affecting the cerebellum and the associated neural organization .
-Headache dizziness : If the patient had a history of hypertension , when cerebral hemorrhage happens , the delivery of high blood pressure will increase , causing headache , dizziness , even accompanied by nausea, vomiting , in the sense of uncomfortable … It is possible that the phenomenon of brain hemorrhage occurred
-Yawn more : In the elderly , due to hardening of the brain arteries , the blood vessels narrowing to make the blood circulation slows down, causing anemia , lack of oxygen to organized brain function causing yawning . If in a few days , the elderly have more yawning repeatedly demonstrated cerebral ischemia and should be aware of stroke.Cerebral arteries or atherosclerosis is the principle cause of cerebral vascular accident .

Precautions

Cerebral vascular accident happened very suddenly , the patient does not feel any pain . Therefore , patients are sometimes can not call helpers , thus more likely to lose precious time is the time we can save the brain ( also called the golden hour ) during the first 3 hours of illness. If complications was discovered late, whether active treatment is easy to leave severe sequelae . Thus , detection and active treatment in the causes of complications is important , such as treatment of hypertension , atherosclerosis , stress , work and rest , regular exercise, do not drink much alcohol … When there are symptoms of headache , dizziness , malaise , unexplained fatigue … , need immediate examination for the early detection and timely treatment .
