Is cerebral hemorrhage serious?
The critical period for cerebral hemorrhage is generally around 14 days, as it primarily involves overcoming two most dangerous phases. The first phase is within three days of the cerebral hemorrhage. This period is most feared for the potential increase in bleeding. Often, if blood pressure is not well controlled, it can easily lead to further bleeding, especially within the first three days which has the highest incidence. The second phase is approximately 10-14 days after the cerebral hemorrhage, because this period marks the peak of cerebral swelling and cerebral vasospasm. The main concern here is severe cerebral swelling and cerebral vasospasm, which can lead to cerebral infarction, and potentially extensive cerebral infarction, possibly resulting in death. Trepanation surgery may be necessary to save the patient.
Is a glioma benign or malignant?
Glioblastoma is the most common form of malignant tumor inside the skull, and the vast majority of glioblastomas are highly malignant. Once changes in this condition are detected, generally, the patient doesn't have much time left. If it is a relatively better glioblastoma, which means it is highly differentiated, the survival time is about 1-2 years. For some poorer glioblastomas, or those with low differentiation, their survival period is often only about six months, and they continuously spread along with nerve fibers to the surrounding areas. They might even metastasize to distant places through cerebrospinal fluid, blood, lymph, and other means. Therefore, even if surgery is used to remove a single lesion, other parts of the body may still demonstrate metastatic lesions. Hence, the treatment approach for this is comprehensive.
What are the symptoms of a stroke?
Symptoms of stroke vary greatly, and it is crucial to judge based on the circumstances. The symptoms are mainly divided into two major categories: hemorrhagic stroke and ischemic stroke. The most common symptoms of hemorrhagic stroke are severe headaches, projectile vomiting, and the gradual onset of consciousness disorders. Some people might also experience limb numbness, weakness, speech impediments, and other conditions. The most common symptoms of ischemic stroke include dizziness, limb numbness, and speech impediments; sometimes, these symptoms alternate, so it is essential to pay attention to clinical observations and focus on differential diagnosis. There are also other types of symptoms, such as cognitive decline, urinary and fecal incontinence, unstable gait, swallowing difficulties, and coughing while swallowing. Therefore, it is imperative to visit a hospital in a timely manner for testing to clearly understand the specific changes in the patient's condition at that time, thus better facilitating the patient’s recovery.
Premonitory symptoms of cerebral infarction recurrence
The symptoms preceding the recurrence of a cerebral infarction mainly involve observing the symptoms presented during the initial incidence of the stroke. In many cases, the recurrent symptoms are very similar to those initially experienced. For example, if dizziness was a symptom during the previous episode, then dizziness could also be a precursor symptom in a recurrence, with similar nature and intensity of dizziness as before. Additionally, if previous symptoms included limb numbness, weakness, or speech impairment, similar signs might precede a recurrence. Clinically, it is imperative to address these issues before an actual recurrence occurs, such as actively pursuing antiplatelet aggregation therapy, lipid-lowering, and stabilizing plaques, and resorting to surgical treatment if necessary, to better reduce the chances of stroke recurrence.
Glioma Symptoms
The symptoms of glioma are numerous, and it is essential to make judgments based on the situation. The most common clinical manifestations are headaches, dizziness, nausea, and vomiting. These symptoms may persist for a relatively long period and are relatively mild, not immediately noticeable at the time. Additionally, some patients may experience a decline in cognitive function, colloquially described as becoming less intelligent. This is especially common in gliomas of the frontal lobe. If the glioma is located in the occipital lobe, it often causes visual disturbances, such as blurred vision and visual field defects. In cases of temporal lobe gliomas, frequent seizures and impaired limb mobility may occur. For cerebellar gliomas, symptoms can include a decline in cognitive function and ataxia, among others.
Is trigeminal neuralgia easy to treat?
Whether trigeminal neuralgia is easy to treat must be judged based on the situation at the time. The vast majority of patients with trigeminal nerve pain can find a corresponding cause, such as compression by blood vessels, tumors, or infection factors. For vascular compression, microvascular decompression surgery can be adopted for treatment. For tumor compression, craniotomy and tumor resection can be adopted for treatment. For some infectious factors, treatment such as anti-infection and hormones can be adopted. These are relatively easier to treat, and most can have a very obvious prognosis. However, there are also cases, such as trigeminal neuralgia where no specific cause has been found, called primary trigeminal neuralgia, where active complete treatment is not possible, and only certain methods can be used to alleviate the general symptoms of the patient and reduce their suffering.
Can gliomas be inherited?
Gliomas have a certain hereditary proportion, but this is not an absolute concept. In clinical practice, there is no clear explanation for the pathogenic factors of gliomas, and theories are generally speculative. For instance, one factor is genetic nature, and there is also some familial clustering which supports the idea of a genetic predisposition. However, it is usually easier to identify purely genetic diseases, but gliomas often involve the inheritance of multiple genes, making it difficult to pinpoint the fundamental factors directly. Additionally, other factors include exposure to radiation and engaging in harmful work, such as producing methanol or solvents, etc. These can also cause genetic mutations leading to gliomas, so the issue is not necessarily solely genetic.
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.
