Several common symptoms of glioma

Glioma patients basically have tumors growing in the brain. This type of tumor is a malignant tumor that will have a great impact on the human brain nervous system and human perception and cognitive abilities. In severe cases, it can even endanger life safety. So what are the common symptoms of glioma? Let me give you a detailed introduction below.

(1) 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.

(2) 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.

(3) Headache: The headache 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.

(4) Olfactory hallucinations: Temporal lobe tumors may cause olfactory hallucinations, where a person may smell an odor that does not exist, such as burnt rice or burnt rubber.

(5) 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.

(6) Mental abnormalities: Brain tumors located in the frontal lobe of the brain can destroy the mental activities of the frontal lobe, causing abnormal mental manifestations such as excitement, agitation, depression, repression, amnesia, and fabrication.

(7) 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, vibration, and body shape in one side of the limb.

(8) Gigantism: It is often seen in pituitary tumors. The patient grows rapidly and develops acromegaly (large chin, nose, lips, tongue, and abnormally large hands and feet).

(9) Tinnitus and deafness: This is often found when making a phone call, that is, one ear can hear but the other ear cannot. This symptom is often a precursor to acoustic neuroma.
