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.

Brain infarction belongs to which department?

Brain infarction is usually classified as a neurology disease. Patients with brain infarction often exhibit clear symptoms of headache, dizziness, nausea, vomiting, and significant swallowing dysfunction, leading to coughing while drinking. Some patients may also experience facial nerve paralysis to some extent, manifesting as unclear speech, difficulty speaking, and articulation disorders. When the aforementioned clinical symptoms occur, the possibility of brain infarction is considered high. Performing a cranial MRI scan for patients can help determine the specific location, number, and severity of the infarction. Generally, it is recommended to treat patients with brain infarction during the acute phase with drugs that enhance brain function, nourish the nerves, and promote blood circulation to remove blood stasis, and many patients can achieve satisfactory treatment results. (Specific medications should be used under the guidance of a physician.)

post-stroke sequelae

Brain infarction is a very common type of ischemic cerebrovascular disease, which mainly includes the following types: the most common are lacunar infarction, cerebral thrombosis, and cerebral embolism. The neurological sequelae of lacunar infarction are not particularly typical, and patients may exhibit mild incomplete paralysis of limbs, decreased muscle strength, reduced sensation, or ataxia. Cerebral thrombosis and cerebral embolism often cause extensive brain infarction, where patients typically experience severe limb paralysis, loss of sensation, increased tendon reflexes, positive pathological reflexes, and an inability to care for themselves.

What tests are done for a cerebral infarction?

For patients with cerebral infarction, it is recommended to take the patient to a local hospital for timely treatment during the acute phase. A cranial CT scan or MRI should be performed to help assess the current situation. Cranial MRI plays an important auxiliary diagnostic role in identifying the specific location, extent, and severity of the cerebral infarction. It is advised to perform a cranial MRI during the acute phase for a clear diagnosis, and then decide the next step of the treatment plan based on the situation. Within the surgical window, thrombolytic therapy can be applied to achieve dissolution of the clot. If the optimal timing for thrombolysis has been missed, it is recommended that the patient be hospitalized to receive treatment, including intravenous drips, brain-nourishing drugs, nerve nutrition, and medications that invigorate blood circulation and remove blood stasis, to help improve the state of ischemia and hypoxia in the brain tissue.

Precursors to cerebral infarction

For patients with cerebral infarction, before the onset of the illness, they often lack specific prodromal symptoms. Some patients may experience mild headaches, dizziness, nausea, and a clear feeling of discomfort. Additionally, some patients might experience numbness in the legs and involuntary twitching of facial muscles before the onset. Subsequently, some patients may also start to have drooping of the corner of the mouth to one side, drooling, slurred speech, and distinct articulation disorders. When these clinical presentations occur, it is necessary to be vigilant and seek timely medical attention at a local hospital. A cranial CT or MRI should be performed to confirm the diagnosis.

How is a cerebral infarction treated?

The treatment principles for cerebral infarction include thrombolysis, anticoagulation, volume expansion, lowering blood pressure, and brain protection. The main goal is to improve the blood circulation in the ischemic area of the brain as soon as possible and promote the recovery of neurological functions. During the acute phase, patients should rest in bed as much as possible, enhance care for skin, oral cavity, respiratory tract, and excretion, and maintain electrolyte balance. If a patient still cannot eat 48 to 72 hours after onset, nasogastric feeding with liquid nutrition should be provided to ensure nutritional supply. The priority should be given to the patient's daily care, diet, and the management of other comorbidities. Since some patients with cerebral infarction cannot take care of themselves during the acute phase and may even have difficulty swallowing, without adequate nutrition, metabolic issues can arise quickly. In such cases, even the best medications can fail to achieve positive outcomes. Since cerebral thrombosis is the most common type of cerebral infarction characterized by high incidence, high mortality, high recurrence rate, and high disability rate, patients may experience mild hemiplegia or severe scenarios leading to loss of life. Therefore, lifelong medication is necessary to prevent recurrence, achieve secondary prevention, and ultimately reduce the recurrence of cerebral infarction.
