Many friends go to the hospital to do brain CT or and MRI tips: lacunar cerebral infarction!
Is lacunar cerebral infarction cerebral infarction cerebral infarction? Will I be paralyzed later? How is it treated? How can this be done? Worried, tangled, anxious, overwhelmed!
First, what is lacunar cerebral infarction
No matter what kind of cerebral infarction, it is cerebral infarction, that is, the cerebral blood vessels are blocked.
1. Does lacunarity refer to capillary blockage?
Lacunar cerebral infarction is not capillaries!
The capillaries are so small that they are almost so small that only blood cells are allowed to pass through, and the capillaries are connected in a network that facilitates the exchange of nutrients and metabolic substances between the arteries and veins.
The capillaries are very small, and we simply cannot see that the capillaries are blocked by common tests such as CT or, MRI or contrast. Besides, even if the capillaries are blocked, we don't have symptoms.
2. Is the lacunar cerebral infarction a minor cerebral infarction?
Nor is it!
There is no concept of "minor cerebral infarction" in medicine. Mild is only that the people feel that the patient's symptoms are mild or no symptoms, it is called mild cerebral infarction, but this is the subjective feeling of the human body, and it cannot be said that no symptoms are mild cerebral infarction, but the symptoms of the patients we see are relatively mild.
In the eyes of many people, mild cerebral infarction is a concept that distinguishes symptoms, that is, although there is cerebral infarction, the patient's symptoms are very mild. But this is a relatively subjective concept, which is difficult to define, so there is no "mild cerebral infarction".
3. So what exactly is lacunar cerebral infarction?
Lacunar cerebral infarction is a non-cortical small infarction caused by occlusion of a single small perforating branch of a large cerebral artery. That is, smaller cerebral infarction caused by occlusion of small arterial vessels in the deeper parts of the brain.
2. Will there be symptoms of lacunar cerebral infarction?
Most of the lacunar cerebral infarction that you usually see has no symptoms, many of them have done a CT or MRI for other reasons, and the result is written on the examination report: lacunar cerebral infarction!
But this is not to say that lacunar cerebral infarction is without symptoms, statistics show that there are also some lacunar cerebral infarction will show symptoms similar to cerebral infarction. The most common symptom is the lack of strength in the arms and legs, or the weakening of the strength of the arms and legs, which accounts for about 50% of lacunar cerebral infarction.
Unilateral arm or leg weakness + numbness, accounting for about 20%. A single arm or leg is numb, accounting for about 14%. Individual arms and legs are inflexible, accounting for about 10%. Slurred speech, drinking water and coughing, accounting for about 4%. Most of them are mild symptoms.
However, there are also very few lacunar cerebral infarctions, which may cause dementia, urinary and urinary incontinence, etc.
Statistics show that the population-wide incidence of lacunar cerebral infarction is about 0.026-0.052%.
3. Who is prone to lacunar cerebral infarction?
1, the elderly, with the increase of age, the risk of our arteriosclerosis will increase, and the risk of atherosclerosis will also increase, then the older the age, relatively speaking, the more people with lacunar cerebral infarction.
2. Family history, people whose parents have a history of cerebral infarction, especially those whose parents have had a clear cerebral infarction before the age of 55, the risk of lacunar cerebral infarction in their children will be increased.
3. Smoking, smoking will significantly accelerate the aggravation of the atherosclerosis process. Smokers have a 3-4 times higher risk of cerebral infarction than non-smokers.
4, four high, people with hypertension, diabetes, hyperlipidemia, hyperhomocysteinemia, whether there is one of them, or a combination of several, then the risk of lacunar cerebral infarction of these people will increase.
Fourth, how to treat lacunar cerebral infarction
1. If there are obvious symptoms of cerebral infarction or there is a clear thrombosis, it must be treated according to the plan of cerebral infarction, including aspirin + statin drugs, to prevent plaque aggravation, to prevent thrombosis, and to prevent cerebral infarction. Thrombolytic therapy is also required for the acute phase.
2. Most of the lacunar cerebral infarction without symptoms does not necessarily require taking aspirin or statin; but it is necessary to see if there is hypertension, diabetes, hyperlipidemia, hyperhomocysteinemia and so on. If there is a need to actively control the four highs regularly.
3. Regardless of whether aspirin and statin are needed, whether there are four highs, for all patients with lacunar cerebral infarction, they should adhere to a long-term healthy lifestyle: stay away from tobacco and alcohol, adhere to exercise, control weight, healthy diet and so on.
But there is no need to worry too much, let alone worry, the prognosis of lacunar cerebral infarction is better, and the mortality and disability rates are relatively low.
But we must control the four highs and adhere to a healthy life to avoid recurrence, so as not to develop into a more serious cerebral infarction!
