What are the precursors of glioma

Brain tumors are a terrible threat to life and can take a person's life at any time. How much do you know about gliomas, which are common in the brain? What are the clinical symptoms that can indicate whether it is serious and what we need to pay attention to? Let's take a look at what are the precursors of gliomas?

1. Headache, nausea, vomiting. Headache is mostly located in the forehead and temporal area. It is a persistent headache with paroxysmal aggravation. The headache is often worse in the morning and can be normal during the intervals.

2. Papilledema and decreased vision.

3. Mental and consciousness disorders and other symptoms: dizziness, diplopia, amaurosis fugax, cataplexy, confusion, mental restlessness or apathy, epilepsy, and even coma.

4. Changes in vital signs: Moderate and severe acute intracranial pressure often causes slow breathing and pulse, and increased blood pressure.

(1) Psychiatric symptoms: They are often manifested as slow reaction, laziness, decreased or even loss of recent memory, and in severe cases, loss of self-awareness and judgment. They may also manifest as irritability, irritability or euphoria.

(2) Epileptic seizures: including generalized seizures and localized seizures, which are most common in the frontal lobe, followed by the temporal lobe, parietal lobe, and least common in the occipital lobe. In some cases, there are precursors before convulsions. For example, in patients with temporal lobe tumors, there are often precursors such as hallucinations and dizziness before an epileptic seizure. In patients with parietal lobe tumors, there may be abnormal sensations such as limb numbness before an epileptic seizure.

(3) Symptoms of pyramidal tract damage: manifested as weakness or paralysis of the half of the body or a single limb contralateral to the tumor and positive pathological signs.

(4) Sensory impairment: manifested as impairment of the position sense, two-point discrimination, pattern sense, texture sense, and entity sense of the limb contralateral to the tumor.

(5) Aphasia: divided into motor aphasia and sensory aphasia.

(6) Visual field changes: manifested as visual field defects and hemianopsia.

Sometimes there are no compression symptoms in the early stages of a tumor. As the tumor grows, it may manifest as compression symptoms of varying degrees. The progression of symptoms may be fast or slow, depending on the location and malignancy of the tumor, the speed of tumor growth, and the degree of progression of the symptoms.
