Symptoms of glioma

Glioma is one of the most common intracranial tumor diseases and a common malignant tumor disease. It is extremely harmful to the human body. Once you are sick, you will suffer a lot. We need to understand the symptoms of glioma in order to detect the disease in time and take good prevention. The following are the 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".
