Any part of the human body has the possibility of infection, thus posing a threat to the health of the body, of which the seriousness of intracranial infection must be clear to everyone, because the brain is the body’s general headquarters, controlling the activities and thinking of the human body, if even the general headquarters are invaded by bacteria, it is more dangerous. It is no exaggeration to say that intracranial infection is one of the most serious diseases in the central nervous system, and it occurs after some cranial surgery, when the patient’s physical quality is poor, it is easy to be attacked by bacteria. What kind of bacteria are usually found in intracranial infections? The common pathogenic bacteria are viruses, mycobacteria, mycoplasma, chlamydia and parasites. Clinically, there are some symptoms of intracranial infection in the early stage, mainly manifesting as fever, headache, vomiting, and some patients may also experience impaired consciousness, even persistent coma and shock, and in serious cases, encephalitis, meningitis and brain abscess, etc. These are all very threatening to health. Intracranial infection is a life-threatening condition, and once similar symptoms are detected, it should be examined and diagnosed in time, and effective methods should be taken to treat and control it. However, the treatment of intracranial infection is relatively tricky, if we simply rely on anti-infective drugs that is far from enough, plus the human brain itself has a layer of blood-brain barrier, general anti-infective drugs can not enter, so the purpose of treatment can not be achieved, so the treatment of intracranial infection or through surgical means.
