Intracranial infection, a very common problem in neurosurgery, for example, after some cranial surgery, this makes some bacteria or viruses can take advantage of the opportunity to enter the central nerve of the brain, resulting in intracranial infection. The danger of intracranial infection is great, if not treated in time it can easily cause cerebral edema, brain herniation, etc., and can even endanger the life, so we must pay attention to it. What are the most typical symptoms of intracranial infection? If you can grasp the knowledge of some symptoms of intracranial infection, it is very beneficial for the timely detection of the disease and timely treatment, the specific performance is as follows: 1, fever. A typical symptom of intracranial infection is that the patient will have fever, which is mainly because the virus invaded the cranium after stimulating the brain tissue, thus causing the patient’s body temperature to rise, the fever will be as high as 40 degrees in more serious cases, the patient will also be accompanied by symptoms of shivering, in addition to shortness of breath, cough, etc. 2. Headache. Intracranial infection will lead to an increase in intracranial pressure, which will stimulate the brain and cause headaches, and in severe cases, patients will also suffer from nausea and vomiting. 3. Impaired consciousness. When intracranial infection is serious, the influence of bacteria will lead to brain tissue edema and brain damage, so there will be varying degrees of impaired consciousness, and even coma. 4. Epilepsy. If the intracranial infection is not controlled in time and the patient’s brain function is affected, it may also cause seizures.
