What are the symptoms of brain glioma

Everyone knows that the structure of the brain is very complex, with nerve cells and brain cells concentrated together. If a brain glioma occurs, it will not only threaten the health of brain cells, but will also have a direct impact on the body. Common symptoms of the disease include headache, decreased vision, mental abnormalities, etc.

Gliomas are the most common primary brain tumors arising from the cancerous transformation of glial cells in the brain and spinal cord. The annual incidence rate is approximately 3-8 people per 100,000 population. Like other tumors (diseases), glioma is caused by the interaction of innate genetic high-risk factors and environmental carcinogenic factors. Some known genetic diseases, such as neurofibromatosis (type I) and tuberculous sclerosis, are genetic susceptibility factors for brain gliomas.

(1) Headache: It is usually severe and often occurs in the early morning. Sometimes the patient wakes up from sleep with pain, but the headache will gradually ease or disappear after getting up and doing some light exercise.

(2) Vomiting: Due to the increase in intracranial pressure, the respiratory center in the medulla oblongata is stimulated, resulting in vomiting. Vomiting often occurs after a headache and is in the form of a jet.

(3) Visual impairment: When intracranial pressure increases, the venous blood return to the eyeball will be blocked, leading to congestion and edema, damaging the visual cells on the retina of the fundus, and causing decreased vision.

(4) Mental abnormalities: Gliomas located in the frontal lobe of the brain can destroy the mental activities of the frontal lobe, causing abnormal mental manifestations such as happiness, restlessness, depression, repression, amnesia, and fabrication.

(5) Unilateral limb paresthesia: The parietal lobe, located in the middle of the cerebral hemisphere, is responsible for sensation. Tumors in this area often lead to decreased or absent sensations of pain, temperature, shock, and body shape recognition in one side of the limb.

(6) Olfactory hallucinations: Tumors in the temporal lobe may cause olfactory hallucinations, meaning that one may smell an odor that does not exist, such as burnt rice or burnt rubber.

(7) Hemiplegia or staggering gait: Cerebellar lesions are more specific, that is, patients often experience hemiplegia or a staggering gait of drunkenness after headache, vomiting, and visual impairment.

(8) Ringing in the ears and deafness: This condition often occurs when making a phone call, where one ear can hear but the other cannot. This manifestation is often a precursor to acoustic neuroma.
