What are the symptoms of glioma

The difficulty of treating any disease in the late stage is greater than that in the early stage, especially some brain tumor diseases, such as glioma. Glioma is difficult to cure and prone to recurrence, so early detection and early treatment are very important. So what are the symptoms of glioma? The following editor will lead you to learn about the symptoms of glioma.

1. Headache: About 30% of patients with brain gliomas experience headaches, and about 70% of them experience gradually worsening headaches. This type of headache is mostly non-specific, but only intermittent, mostly located on the same side of the lesion, and often manifests as dull pain rather than throbbing pain, which is sometimes difficult to distinguish from tension headaches.

2. Mental changes: About 15% to 20% of glioma patients have changes in mental state as the first symptom, mainly manifested in changes in emotions, personality, cognitive function, calculation ability and memory.

3. Focal neurological symptoms: The different locations of the tumors can also cause corresponding neurological deficit symptoms, such as limb paralysis, sensory impairment, aphasia, unsteady gait, hemianopsia, alexia and agraphia.

4. Cranial nerve symptoms: Damage to different cranial nerves will produce corresponding neurological symptoms, such as decreased vision, diplopia, strabismus and facial paralysis.

4. Phantom Smell

Tumors in the temporal lobe can cause olfactory hallucinations, that is, the smell of an odor that does not exist, such as burnt rice or burnt rubber.

5. 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.

6. Epileptic seizures

About one-third of patients with brain gliomas experience epileptic seizures, and the incidence increases to 50-70% during the course of the disease. Half of the epilepsy is localized, while the other half is generalized. The probability and manifestation of epileptic seizures caused by gliomas in different parts of the body are not the same. In addition to causing systemic seizures, epileptic seizures caused by tumors in different parts often have their own characteristics: for example, frontal lobe gliomas can cause paroxysmal convulsions and aphasia in the contralateral limbs; medial temporal lobe tumors are often accompanied by olfactory hallucinations, paroxysmal fear, and palpitations; and parietal lobe tumors can cause hemisensory disorders.

7. Mental changes

About 15% to 20% of glioma patients experience changes in mental state as the first symptom, mainly manifested in changes in emotions, personality, cognitive function, calculation ability and memory.
