Intracranial tumor sounds like a terrible disease, but in fact, it is one of the common diseases among the elderly, and the early symptoms are similar to cerebrovascular disease, epilepsy and psychiatric diseases. Therefore, when the following symptoms appear in the elderly, we should consider the possibility of having intracranial tumor: 1. Mental disorder Intracranial tumor often causes mental abnormalities in patients. The early mental disorder caused by intracranial tumor is mainly manifested as dizziness, headache, insomnia, emotional indifference, mental retardation, poor memory and so on. When the disease is serious, patients with mental disorder often show giggling, disorganized language, disorientation, lack of self-control and difficulty in understanding; some may also show movement disorder and behavior disorder. Therefore, if elderly people have mental abnormalities, they may suffer from intracranial tumors in addition to mental illness. 2. Sudden loss of vision Intracranial tumor may cause sudden loss of vision. This symptom is not obvious at the early stage of the tumor, but when the tumor gradually increases and compresses the optic nerve, it can cause optic nerve atrophy, resulting in sudden loss of vision or even blindness. In addition, these patients often have visual field defects, and often need to tilt their heads and squint to see an object clearly. Therefore, when such symptoms occur in the elderly, the possibility of intracranial tumors should be considered. 3. Sudden onset of epilepsy Epilepsy patients are mostly teenagers within 20 years old, if epilepsy occurs suddenly in the elderly, it may be caused by intracranial tumor. According to clinical research, more than 1/3 of patients with intracranial tumors will have epilepsy symptoms. These patients with epileptic symptoms will have continuous and frequent convulsions, and their consciousness will not be restored during the interval of convulsions, which can be life-threatening if not rescued in time. In general, tumors growing in the anterior part of the brain, near the cerebral cortex, are prone to epilepsy, and most of these tumors are benign or less malignant. If these tumors are diagnosed early and operated on in a timely manner, satisfactory results can be achieved. The most important thing is that the patient has been suffering from epilepsy for a long time, so they are often mistaken for having epilepsy, and the treatment is delayed. This kind of headache often occurs at four or five o’clock in the morning, and patients are often awakened by pain in their sleep, and after getting up and moving around, the symptoms will gradually reduce or disappear at eight or nine o’clock in the morning. This is because the intracranial tumor will cause partial obstruction of the spinal fluid in the brain circulation. Therefore, patients with intracranial tumor are most likely to have cerebrospinal fluid obstruction after sleep, and then develop hydrocephalus; in the morning, due to the increase of hydrocephalus, patients will have severe headache. After getting up, the circulation of cerebrospinal fluid will be accelerated and the headache can be temporarily relieved. Therefore, when elderly people often have early morning headache, they should consider the possibility of having intracranial tumor. Knowing the above symptoms, one should pay attention in daily life and prevent intracranial tumor disease.
