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.
How to deal with hydrocephalus?
The treatment of hydrocephalus must clearly identify the severity of the condition. Hydrocephalus can be categorized into acute and chronic types. In cases of acute hydrocephalus, emergency ventricular puncture drainage surgery is required, otherwise, it may cause brain herniation leading to death. For chronic hydrocephalus, it is crucial to distinguish whether it is communicating hydrocephalus or obstructive hydrocephalus. For obstructive hydrocephalus, treatment options include creating a patency in the cerebral aqueduct and third ventriculostomy. For other types of hydrocephalus, ventriculoperitoneal shunt surgery can be performed. Therefore, it is essential to clearly determine the type of hydrocephalus to fundamentally select the appropriate surgical methods and instruments.
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.
Glioma causes
In clinical practice, the etiology of gliomas is not very clear. It is not as straightforward as how smoking can easily lead to lung cancer or how cirrhosis can easily lead to liver cancer; many factors are speculative. For example, the most common theory in clinical practice involves genetics. Any form of genetic mutation or chromosomal mutation can induce the development of a glioma. For instance, excessive radiation exposure and drug abuse, and even maternal-fetal transmission or a genetic predisposition, could cause chromosomal abnormalities in patients, potentially leading to the formation of gliomas. However, the most fundamental cause has not yet been clearly identified.
Is it good to drink milk after a stroke?
Patients with cerebral infarction can drink milk, but it must be analyzed according to the specific condition at the time because patients with cerebral infarction often experience coma and accompanying dysphagia with coughing. In such cases, drinking milk is not a problem, but attention must be paid to changes in dietary habits. If necessary, a gastric tube must be inserted through the nose into the stomach for feeding to avoid direct oral intake, which can cause coughing, aspiration, and lead to pneumonia. Therefore, this point must be carefully considered. For ordinary people in daily life, a cup of milk a day is a very good choice because milk mainly contains protein and does not contain a lot of fat and sugar. For patients with cerebral infarction, this diet is very ideal. If fresh milk can be used in everyday life, it is more beneficial for promoting the patient's recovery.
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.
Is glioma cancer?
Gliomas are the most common type of malignant tumor within the skull, and they are also a form of cancer. Cancer is a very broad term essentially describing a process where some cells proliferate abnormally and differentiate without dying, and gliomas proliferate in the same way. To give an analogy, think of a bunch of villains: if there are heroes to suppress and resolve these villains, then generally, people would not develop tumors. However, if this group of villains gradually becomes stronger and defeats the heroes, then these villains gather within the body, forming a tumor. The same principle applies to the formation of cancer. Therefore, for such cases, it is crucial to detect cancer early and begin the appropriate treatment. Early treatment can have some very beneficial effects on the prognosis for the patient.
Can the blood vessels in a cerebral infarction be unblocked?
Whether the blood vessels in a cerebral infarction can be reopened is closely related to time. If it is within the hyperacute phase, which means within six hours from the onset of clinical symptoms to hospital admission, the majority of cases can undergo thrombolysis intravenously, or arterial thrombectomy to reopen the blood vessels. However, if the time exceeds this window, reopening is no longer feasible, and forced reopening at this stage can easily lead to the detachment of distal thrombi or cause reperfusion injury, which is more detrimental to the patient's condition. Therefore, it is impossible to reopen the blood vessels during the chronic phase or non-hyperacute phase. If treatment of this vascular occlusion is desired, vascular anastomosis can be considered, though the specific type of anastomosis surgery depends on the patient's specific condition at the time. Thus, the possibility of reopening a blood vessel in a cerebral infarction certainly depends on timing.
What is brachial plexus neuropathy?
Brachial plexus neuropathy occurs when certain pathological changes affect the brachial plexus, causing clinical symptoms such as pain, numbness, and weakness. The brachial plexus is composed of four nerves from cervical vertebrae 6 to 7, 8, and thoracic vertebra 1. The brachial plexus gives rise to the median nerve, ulnar nerve, and radial nerve, making it a central hub. If the brachial plexus is injured, for instance, through trauma such as stretching, tearing, tumor compression, or bone impingement, this can lead to clinical manifestations including pain, numbness, and weakness in the arms and hands, a condition known as brachial plexus neuropathy. If such symptoms occur, it is crucial to promptly complete the necessary examinations to clarify the changes in the condition.
