What details should be paid attention to when a glioma occurs

Some people may experience headaches, vomiting, and other symptoms in their daily lives. In severe cases, they may experience vision loss, epilepsy, and mental abnormalities. In this case, you should pay attention and go to the hospital for further examination. Brain glioma is a common disease today. Let's take a look at what details to pay attention to when a glioma occurs.

Glioma usually has no typical symptoms at the beginning. As the tumor grows, it will show the following symptoms: one is increased intracranial pressure and other general symptoms, such as headache, vomiting, vision loss, diplopia, epileptic seizures and mental symptoms. The other is local symptoms caused by the compression, infiltration and destruction of brain tissue by the tumor. The local symptoms vary depending on the location of the tumor.

Glioma is an infiltrative growth with no clear boundary between it and normal brain tissue. It is difficult to completely remove it, is not very sensitive to radiotherapy or chemotherapy, and is very prone to recurrence. Benign and malignant tumors growing in important parts of the brain are difficult to remove surgically or cannot be removed at all. Chemical drugs and general anti-tumor Chinese medicines are not ideal in efficacy due to the influence of factors such as the blood-brain barrier. Therefore, brain glioma is still one of the tumors with the worst prognosis among all tumors in the body.

Vomiting is caused by stimulation of the medullary vomiting center or the vagus nerve, and may be projectile without nausea. In children, the headache may not be obvious due to cranial suture separation, and because posterior cranial fossa tumors are common, vomiting is more prominent.

Increased intracranial pressure can cause papilledema, which in turn can lead to secondary atrophy of the optic nerve and decreased vision. Tumors compressing the optic nerve can cause primary optic atrophy, which can also lead to decreased vision. The abducens nerve is easily compressed and pulled, often causing paralysis and double vision.

Some tumor patients have epilepsy symptoms, which may be early symptoms. Epilepsy that begins in adulthood is generally symptomatic and is mostly caused by brain tumors. Those who are difficult to control with drugs or whose seizures change in nature should be considered to have brain tumors. Those with tumors adjacent to the cortex are more likely to develop epilepsy, while those with tumors deep inside are less likely to develop epilepsy. Localized epilepsy has localization significance.

Some tumors, especially those located in the frontal lobe, may gradually cause psychiatric symptoms such as personality changes, indifference, decreased speech and activity, inattention, memory loss, lack of concern for things, and lack of cleanliness.

Local symptoms will occur according to the location of the tumor, and will progressively worsen. Especially for malignant gliomas, which grow faster, infiltrate and destroy brain tissue, and cause significant surrounding brain edema, local symptoms are more obvious and develop faster. Intraventricular tumors or tumors located in the quiet area may have no local symptoms in the early stages. Tumors in important functional areas such as the brainstem will show local symptoms in the early stages, and symptoms of increased intracranial pressure will not appear until a considerable period of time. Some tumors that develop more slowly often do not show symptoms of increased intracranial pressure until the late stages due to compensatory effects.
