Why do patients with cerebral infarction suffer from weakness in their legs and how long does it take to get better?
We can divide it into three questions, what is a cerebral infarction? Why are the feet weak for cerebral infarction? How long will it be better?
Cerebral infarction is a brain infarction.
Blood runs in the blood vessels, transporting oxygen, nutrients, metabolic waste, etc. As you get old or your body is not so healthy, some plaques, garbage, etc. are prone to appear. When these masses of garbage run through the blood, they are fine in the large blood vessels. Once they reach the small blood vessels, they are easy to block. Blood vessels, when it runs to the smaller branch blood vessels in the brain, it is easy to block the blood vessels in the brain. There is no blood flow in the blood vessels after the blockage occurs. There is no way for nutrients and oxygen to pass, and the brain tissue it nourishes Will be ischemia and hypoxia.
If the infarction is quickly washed away and the blood is reperfused, the brain tissue damage will be small; if the infarction time is too long, the brain tissue damage will be large.
Why does cerebral infarction feel weak?
The brain is our control center. Movement and sensation of the whole body can be found in an area in the brain.
Strictly speaking, it is possible not only for the feet, but also for the whole body. The most common is half of the body, hands and feet. Different parts of the infarction will have different manifestations. Some are just mild dizziness, some are crooked mouth, some are weakness of half of the body, and some are completely paralyzed.
The brain is divided into two halves. Normally, our brain controls our hands and feet. In other words, the brain on the left controls our hands and feet on the right; the brain on the right controls our hands and feet on the left.
When there is a problem with the area that controls our hands and feet in the brain, the hands and feet that are controlled by it will have problems.
The feeling and movement of the feet are adjacent areas in the brain. The one that controls the movement is a little before the top of the head; the one that controls the sensation is a little behind the top of the head.
When there is a problem in the area that controls the sensation, it is manifested as numbness, decreased sensation, and no sensation; when there is a problem in the area that controls the movement, it is manifested as weakness, unable to move, unable to lift, unable to walk, etc.
Through the above description, we can know that when an infarction occurs in the motor area of the brain that dominates the foot, there will be signs of weakness in the foot. However, both feet are weak, it is necessary to see if there is an infarction of the brain on both sides.
My feet are weak after cerebral infarction. How long will it take?
The same is the weakness of the feet, light and heavy.
The onset of cerebral infarction is already known, but the blood vessel is not blocked.
If the infarction is washed away within a few minutes after the blockage, the brain tissue will not be greatly damaged. After the blood is recirculated, it can be restored again, and the weakness of the feet will be quickly restored for a few hours. The weakness of the inner feet is greatly improved.
If blocked, within four or five hours, the infarction is washed away again, the brain tissue will not only be ischemia and hypoxia during these four or five hours, but there will also be local edema, but the scope is not large. After the blood is restored, it will promote the differentiation of the surrounding brain tissue and the brain cells will take over the control of the foot. When it is controlled again, the weakness of the foot will be restored.
If it is not recanalized for a long time after being blocked, or the blocked blood vessel is relatively large, and there are more brain tissues that nourish it, it will cause a large amount of brain tissue edema and necrosis. It is more difficult to establish control, the more broken, the slower it will be to repair. And the longer the time, the harder it is. This kind of early functional exercise should be strengthened to let the brain know that there are areas dominated by hands and feet to be established quickly.
This is my understanding of " patients with cerebral infarction, why the legs are weak, and how long will it take? " some understanding, popular science articles, not easy to spread, I look forward to your praise, Reward, forward, follow, if you have any questions, please leave a message in the comment area.
