Gliomas originate from neurointerstitial cells, i.e., glial, ventricular canal, choroid plexus epithelium, and neuroparenchymal cells, i.e., neurons. Most tumors originate from different types of glia, but based on the similar histogenetic origin and biological characteristics, all kinds of tumors that occur in the neuroectoderm are generally referred to as gliomas. As the tumor gradually increases in size, it forms intracranial occupying lesions and is often accompanied by peripheral cerebral edema, which produces increased intracranial pressure when the compensatory limit is exceeded. The cause of this disease is not clear yet, but Chinese medicine believes that it is mostly due to fright or anger, or depression and weeping, which makes the qi and blood flow abnormal and the resistance weak, and the disease evil takes advantage of the weakness to develop into cancerous tumor. The typical symptoms of glioma are as follows: optic nerve atrophy, inattention, and nausea. One is the increase of intracranial pressure and other general symptoms, such as headache, vomiting, loss of vision, diplopia, seizures and psychiatric symptoms, and the other is the local symptoms caused by the compression, infiltration and destruction of brain tissue by the tumor, resulting in neurological deficits. Headache is mostly caused by the increase of intracranial pressure, which gradually increases with the growth of tumor, compressing and involving pain-sensitive structures such as blood vessels, dura mater and some cranial nerves, mostly jumping pain, swelling pain, mostly in frontal-temporal or occipital area, and for tumor in one hemisphere, headache can be mainly in the affected side. With the development of tumor, the headache gradually worsens and lengthens in duration. Vomiting is caused by the stimulation of the medullary vomiting center or vagus nerve, which may be jet-like without nausea. Increased intracranial pressure may produce optic papillar edema and cause secondary atrophy of the optic nerve for a long time, resulting in decreased visual acuity; tumor compression of the optic nerve produces primary optic nerve atrophy, also resulting in decreased visual acuity; the abducens nerve is easily squeezed and pulled, often resulting in paralysis and diplopia.
