What are the symptoms of glioma

Each of us longs for a safe and healthy life, but unfortunately, there are always some people who are sad and in pain because of glioma, which brings great harm to their body and mind. Some of them are suffering from glioma, but they are not discovered and treated in time, which leads to their condition worsening. So what are the symptoms of glioma?

The symptoms mainly manifest in two aspects.

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 compression, infiltration, and destruction of brain tissue by the tumor, resulting in neurological dysfunction. Headaches are mostly caused by increased intracranial pressure. As the tumor grows, the intracranial pressure gradually increases, compressing and pulling on pain-sensitive structures in the skull, such as blood vessels, dura mater, and certain cranial nerves, causing headaches. Most of them are throbbing pain and distending pain, mostly in the frontal, temporal, or occipital regions. For superficial tumors in one cerebral hemisphere, the headache may mainly occur on the affected side. The headache starts intermittently, mostly occurring in the early morning. As the tumor develops, the headache gradually worsens and lasts longer. Vomiting is caused by stimulation of the medullary vomiting center or the vagus nerve, and there may be no nausea at first, and it is projectile.

In children, headache may not be significant due to cranial suture separation, and vomiting is more prominent because tumors in the posterior cranial fossa are common. Increased intracranial pressure can cause papilledema, and over time it can cause secondary atrophy of the optic nerve and decreased vision. Primary optic atrophy occurs when the tumor compresses the optic nerve, which also causes 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 begins in adulthood and is generally symptomatic, mostly caused by brain tumors. Those who are difficult to control with drugs or have changes in the nature of seizures should consider the presence of brain tumors. Tumors adjacent to the cortex are prone to epilepsy, while those deep in the cortex are rare. Localized epilepsy has localization significance. Some tumors, especially those located in the frontal lobe, may gradually develop mental symptoms, such as personality changes, indifference, reduced speech and activity, lack of concentration, memory loss, lack of concern for things, and lack of cleanliness. Local symptoms will produce corresponding symptoms depending on the location of the tumor, and they will progressively worsen. Malignant gliomas, in particular, grow rapidly, infiltrate and destroy brain tissue, cause significant surrounding brain edema, have obvious local symptoms, and develop rapidly.
