What exactly is cerebral thrombosis? How to prevent this disease?

Cerebral thrombosis is the most common type of cerebral infarction. Atherosclerosis of the main cerebral arteries or cortical branches leads to blood vessel thickening, lumen stenosis, occlusion, and thrombosis, resulting in reduced local blood flow or interruption of blood supply to the brain. Ischemia and hypoxia in the brain tissue lead to softening and necrosis, and the occurrence of focal nervous system Symptoms and signs. Therefore, it is also called "atherosclerotic cerebral thrombosis" or "thrombotic cerebral infarction" clinically.

Cerebral thrombosis Cerebral thrombosis is a type of ischemic cerebrovascular disease, which is more common in middle-aged and elderly people. There is no obvious gender difference in people. It is caused by the lesions of the cerebral blood vessel wall itself.

Cerebral thrombosis generally has a slow onset, and it may take dozens of hours to several days from onset to peak condition. This disease often occurs during sleep or during quiet rest. Some patients often do not have any aura symptoms before going to bed and find hemiplegia or aphasia when they wake up in the morning. This may be related to low blood pressure and slow blood flow during rest. However, some patients who develop the disease during the day often experience dizziness, numbness and weakness in their limbs. and prodromal symptoms such as transient ischemic attack.

The most common cause of cerebral thrombosis is arteriosclerosis. Due to cerebral arteriosclerosis, the lining of the lumen is rough and the lumen becomes narrow. Under certain conditions, such as lowered blood pressure, slow blood flow or thick blood Under the influence of factors such as increased blood pressure and enhanced platelet aggregation, coagulation factors agglomerate in the lumen and form thrombus, causing vascular occlusion and interruption of blood flow. This results in ischemia, hypoxia, softening, and softening of the brain tissue in the blood supply area. Disease caused by necrosis.

Cerebral thrombosis can occur in any segment of cerebral blood vessels, but clinically, thrombosis formed by the branches of the internal carotid artery, anterior cerebral artery, and middle cerebral artery is more common. The patient presented with central hemiplegia, facial paralysis and hypoesthesia of the contralateral limbs. Most patients are conscious, and headaches and vomiting are rare. However, if the main trunk of the anterior cerebral artery or middle cerebral artery is blocked to form a large-scale cerebral infarction, the condition will be more serious, often accompanied by symptoms of disturbance of consciousness and increased intracranial pressure. When vertebrobasilar system thrombosis occurs, symptoms such as dizziness, nausea, vomiting, diplopia, crossed motor and sensory disorders, dysarthria, dysphagia, and choking on drinking water are common. Symptoms

Cerebral thrombosis Cerebral thrombosis is a common brain disease in the elderly and a common type of cerebrovascular disease. Experts remind you to explain the early symptoms of cerebral thrombosis.

1. Sudden temporary blindness or blurred vision;

2. Sudden aphasia, or unclear articulation or difficulty speaking, but "understands in the heart" (clear consciousness) And it quickly returns to normal without leaving any trace;

3. Unexplained mental decline, difficulty concentrating, difficulty thinking about problems, and reduced work efficiency;

4. Cerebral arteriosclerosis (fundus examination) or high blood pressure is detected, or blood lipids and blood viscosity are increased, and the cerebral blood flow diagram shows changes in insufficient blood supply;

5. Recently, the hands and feet are numb or weak, and the hands are holding Objects suddenly fall to the ground;

6. Frequent dizziness, and some even faint to the ground suddenly, but wake up quickly;

7. Memory impairment has occurred recently, especially significant memory loss , or even completely forgotten. How to prevent

1. Live a regular life

Only by maintaining a good life routine can cerebral thrombosis be avoided. For example, if you cannot fall asleep immediately after a meal, blood usually accumulates in the gastrointestinal tract after a meal. within, reducing blood supply to the brain. It is easy to lower blood pressure in the long term, reduce the blood supply to the brain, and gradually form thrombus, so you can only go to bed half an hour after a meal.

2. Adjust your diet

Develop good eating habits and eat more foods to prevent cerebral thrombosis, which can help reduce blood viscosity and effectively prevent blood coagulation.

3. Drink enough water

If the body is dehydrated for a long time, the viscosity of the blood will increase, and the waste in the body cannot be discharged in time, so you must ensure enough water to prevent cerebral thrombosis. Formation, the daily drinking water consumption should reach more than 2500 ml.

4. Quit smoking and alcohol

Stop smoking and limit alcohol consumption, limit salt intake to no more than 5 grams per day, and avoid fatty foods. Balance work and rest, and use your brain in moderation and not for too long. People under 60 years old should take a break of about 10 minutes after using their brains for 1 hour. People over 60 years old should take a 5 to 10 minute break after using their brains for half an hour to avoid being too tired. induce stroke.

5. Avoid going to bed after a meal

After a meal, blood gathers in the gastrointestinal tract to help the blood supply to the digestive organs, while the blood supply to the brain is relatively reduced. Sleeping, blood pressure drops, can further reduce the blood supply to the brain, slow blood flow, and easily form thrombosis. Therefore, it is best to go to bed half an hour after a meal.

6. Control weight

Consume excess fat in the body through exercise to lower blood lipids and reduce the risk of stroke. Use drugs with caution: Prolonged use of hypnotics, sedatives, antipsychotics, hemostatics, diuretics, heat-clearing drugs (such as compound aminopyrine), and anti-asthma drugs (such as aminophylline) can increase the chance of stroke.

7. Emotional care

Emotions should be stable, always maintain an optimistic, open-minded, and happy mood, and avoid ecstasy, anger, worry, and sadness. Because of long-term mental stress and mood swings, it is easy to cause disorders in the regulation of nerve and body fluids, causing disorders of heart and brain blood circulation and triggering strokes.

8. Pay attention to weather changes

The elderly have weakened ability to adapt to the weather. Overcooling and overheating can increase blood viscosity and induce stroke. Corresponding precautions should be taken.
