Stroke is a very serious disease; its essence lies in the ischemic necrosis of nerve cells. A characteristic of nerve cells is that once they undergo ischemic necrosis, they cannot regenerate. Along with cardiac muscle cells, they are the only cells in the human body that cannot regenerate once they have died. Therefore, for the part of the tissue where nerve cells have already died, such as in cases of cerebral thrombosis or stroke where the tissue has already been affected, it is impossible to completely restore it. If the affected area is relatively small, some compensation might be possible. However, if the affected area is relatively large, this will lead to a significant amount of ischemic necrosis in the neural tissue, which can cause total dysfunction of various tissue structures in the body, and in more severe cases, can lead to coma and eventually the death of the patient. Therefore, it is imperative to take this seriously in clinical practice.

Is a grade II cerebral infarction serious?

A second-degree cerebral infarction is a very serious matter that must be given significant attention clinically. Once a cerebral infarction occurs, it indicates very poor vascular quality. If proactive treatment and prevention are not undertaken to prevent further progression, the symptoms of cerebral infarction can worsen and recur frequently. This can cause severe harm not only to the patient but also to their family and society. This is particularly true for patients with severe, long-term bedridden hemiplegia, which further increases the burden on families and society. Therefore, once a cerebral infarction occurs, regardless of the circumstances, it is crucial to complete the necessary examinations and take timely treatment measures to better manage the progression of the condition.

Can a cerebral infarction recover?

Most patients who experience a stroke have relatively good recovery after active treatment and rehabilitation exercise, but very few patients can recover to the physical state they were in before the stroke. This is mainly because after the stroke, brain cells are damaged due to ischemia and hypoxia. Since brain cells are non-regenerative tissues, it is difficult for them to regenerate once they are damaged. The function of the damaged brain cells is mainly compensated by the undamaged brain neurons. Therefore, even with active treatment, it's not possible to return to a completely normal state. However, even so, it is still crucial to actively pursue treatment and rehabilitation exercises after a stroke, as these can significantly reduce the disability and mortality rates caused by the stroke.

What is a cerebral infarction?

Cerebral infarction is essentially a manifestation of ischemic necrosis of nerve cells. However, in clinical practice, there are many factors that can cause cerebral infarction. It is essential to treat the underlying causes to effectively prevent the further occurrence and progression of cerebral infarction. One characteristic of nerve cells is that once necrosis occurs, they cannot regenerate. Consequently, all patients who suffer from cerebral infarction may have some residual neurological deficits. Mild symptoms include headaches and dizziness, while severe cases may experience numbness and weakness in the limbs, speech impairments, and even more severe conditions such as a vegetative state or death. Therefore, in the case of cerebral infarction, it is crucial to focus on prevention early on to reduce the extent of necrosis. This can effectively ensure one's safety and reduce the occurrence of various complications and sequelae.

Is a lacunar infarct a minor stroke?

Lacunar stroke is, in a sense, a milder form of stroke. It may not involve complete paralysis of limbs or consciousness disorders. Such cases typically show symptoms of sudden large vessel blockage. However, it results from blockages in many small vessels and manifests in various ways. Additionally, it gradually worsens, displaying an increasing range of symptoms including cognitive impairments, dementia, unstable gait, slurred speech, and dysarthria. These symptoms significantly affect the quality of life, so it can be considered not mild.
