Elderly people who experience a cerebral infarction (stroke) may show several typical symptoms if the condition worsens. Firstly, their speech may suddenly become unclear, accompanied by a slight drooping of the mouth and drooling. Another symptom is difficulty in extending the tongue straight out, as it may not align centrally. Additionally, there may be weakness in the limbs. These symptoms indicate the presence of a new cerebral infarction lesion. In such cases, it is crucial to promptly go to the hospital for a head CT scan or an MRI to determine whether the scope of the stroke has expanded or if a new stroke has occurred.

Is a cerebral infarction serious?

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.

Can cerebral infarction be cured completely?

Stroke is not a disease that can be completely cured. Instead, the goal of treatment is to prevent further occurrences and developments of stroke, and there is also the potential for some relative improvement later on. This is considered a very good treatment goal. In the case of stroke, it involves the ischemic necrosis of nerve cells. Additionally, nerve cells have a characteristic that once they die, they cannot regenerate. Therefore, in clinical practice, there are no treatments available that can promote the regeneration of nerves. Treatment can only compensate for the functions of the surrounding healthy nerves to take over the functions of the dead nerves. However, this compensatory process is very slow, often taking two to three months to show significant progress. Hence, it is necessary to continue active rehabilitation exercises later to promote the formation of this compensatory mechanism.

Methods of Cerebral Infarction

There are many methods for treating cerebral infarction, but it is essential to make judgments based on the situation, as each patient's condition is different and requires different treatment approaches. For patients with acute cerebral infarction, treatments such as emergency thrombolysis or thrombectomy can be undertaken. For chronic cerebral infarction, initially, medical treatment is applied, including managing blood pressure, lowering blood lipids, stabilizing blood sugar levels, quitting smoking and alcohol, etc. Subsequently, this includes the oral administration of antiplatelet aggregation medications, which can effectively reduce the recurrence of cerebral infarction. Finally, corresponding surgical treatments are considered, including endarterectomy, superficial temporal artery to middle cerebral artery anastomosis, and appropriate stent implantation surgeries, depending on the specific characteristics. (Specific medications should be administered under the guidance of a physician.)

How to treat cerebral infarction?

The choice of treatment for cerebral infarction depends on the specific circumstances. Treatment plans for small and large cerebral infarctions are completely different, as are the treatment plans for acute and chronic stages of cerebral infarction. For small areas of acute cerebral infarction, many cases can be treated with intravenous thrombolysis and arterial thrombectomy, which are currently very effective treatments that can significantly help in emergency situations. In the chronic phase, it is necessary to actively improve cerebral circulation, brain protection, lower lipids, stabilize blood sugar, and blood pressure, among other methods, to delay the further progression of the disease. Some cases may also require identifying the cause and opting for surgical interventions, including stent implantation and endarterectomy surgeries.

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.
