The incidence of glioma is about 35.26%-60.96% of brain tumors, and it is a malignant tumor that can cause serious harm to patients. In general, the following symptoms are common in glioma patients. First: intracranial hypertension. Intracranial pressure is a common symptom of brain tumor patients, which mostly shows headache, dizziness, nausea and vomiting as mentioned above, and the symptoms are more serious in the morning and evening. We should not confuse the headache symptoms of brain tumor with other headaches. Headache of brain tumor is more common with swelling pain and tearing pain, and the headache is intermittent at first, and gradually worsens with the aggravation of the disease, and the headache symptoms are persistent. In addition, vomiting often accompanies headache and dizziness. Vomiting caused by brain tumor is obviously different from vomiting caused by gastrointestinal discomfort, as vomit is mostly jet-like and commonly occurs after meals. Second: Epilepsy. Epilepsy appears in some patients and can be an early symptom. Usually epilepsy begins in adulthood the latter is usually symptomatic and mostly due to brain tumors. The presence of a brain tumor should be considered in anyone whose seizures are not easily controlled by medication or have a change in nature. Tumors adjacent to the cortex are prone to epilepsy, while those deep within are rare. Third: Psychiatric symptoms. Some tumors, especially those located in frontal lobe, may gradually develop psychiatric symptoms, such as personality change, indifference, reduced speech and activities, inattention, memory loss, lack of concern for things, not knowing neatness, etc. Fourth: Local symptoms. The local symptoms of glioma depend on the location of the tumor and are progressively aggravated with the growth of the tumor. Especially for malignant glioma, it grows faster and infiltrates and destroys the brain tissue, and the surrounding brain edema is also significant, so the local symptoms are more obvious and develop faster. Tumors in the intracerebroventricular region or tumors located in the quiet zone may have no local symptoms in the early stage. In contrast, tumors in the brainstem and other important functional areas show local symptoms in early stage and it takes a long time before the symptoms of increased intracranial pressure appear. For some tumors that develop slowly, the symptoms of increased intracranial pressure often appear only in late stages due to compensatory effects. Although the above symptoms are obvious in glioma patients, they are easily confused with other symptoms, especially in areas with poor medical conditions, and it is difficult to make an accurate diagnosis of the disease. In general, if symptoms such as headache and dizziness have been present for a long time and have not been relieved by symptomatic treatment, but have gradually worsened, it is necessary to go to the hospital for a cranial CT or MRI examination to see if an occupying lesion has appeared in the skull, so as to prevent the problem from occurring in the first place. If there is a problem, it is important to receive treatment in a timely manner.
