What are the symptoms of glioma

Glioma is one of the most common malignant tumors with a high incidence rate. Although it is very harmful, as long as we actively prevent it and understand the symptoms of the disease, we can still avoid the physical and mental pain it brings to us. So what are the specific symptoms of glioma? Let's learn about it together.

The top ten symptoms of glioma:

(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.

(10) Growth cessation in young children: This is common in craniopharyngioma. Clinical manifestations are that a 15- or 16-year-old is only 5 or 6 years old in height, sexual characteristics are not developed, and the belly is full of fat, which makes him look like a "preteen".
