The difference between dizziness of brain tumor and ordinary dizziness is that brain tumor is accompanied by some neurological symptoms and symptoms of elevated intracranial pressure on the basis of dizziness, and most of them are progressively aggravated, and intracranial space-occupying lesions can be seen on examination. On the other hand, ordinary dizziness is mostly functional, which can be relieved after eliminating the triggers, and the examination usually will not find obvious organic lesions. 1. Dizziness caused by brain tumor: when the tumor occurs in the brain, especially in the cerebellum, the tumor destroys the balance function of the cerebellum, and dizziness can occur. And the dizziness will continue to worsen with the increase of tumor volume and may be accompanied by other symptoms, such as headache, nausea and vomiting, poor appetite caused by the increase of intracranial pressure. When there is a tumor in the skull compressing the functional areas of brain tissue, the patient may have hemiparesis, walking crookedly, numbness of hands and feet, speech disorder and other symptoms. Cranial CT and cranial MRI can find occupying lesions, which can be treated symptomatically, and if necessary, surgery can be taken for treatment. 2. Ordinary dizziness: Ordinary dizziness is generally functional and does not cause serious symptoms such as numbness of hands and feet and motor disorders. Functional dizziness is triggered by many factors, such as overwork, late night, emotional fluctuations and insufficient blood and oxygen supply to the brain. This kind of people’s clinical manifestations are mostly dizziness, lightheadedness, blurred vision, etc., which are usually paroxysmal or persistent, and the symptoms can be improved or alleviated after eliminating the triggering factors leading to dizziness. Whether it is brain tumor dizziness or common dizziness, all need to actively seek medical treatment, under the guidance of the doctor strictly comply with the doctor’s prescription treatment.
