High cerebral pressure refers to increased intracranial pressure. The volume of the patient’s skull is fixed, and symptoms of high intracranial pressure occur when the contents of the skull increase, including increased brain volume due to cerebral edema, occupying effects such as tumors or hemorrhages in the brain tissues, significant increase in blood flow to the brain, and hydrocephalus due to increased secretion of cerebrospinal fluid. All of the above diseases can cause increased brain pressure, and a few of the most common are central nervous system infections, brain hemorrhages, and brain tumors. Patients with high cranial pressure will show headache, nausea, vomiting, consciousness disorder, and positive signs of meningeal irritation. Vomiting can be projectile, and the vomit can be stomach contents, or coffee-like liquid if accompanied by a stress ulcer. High cranial pressure requires active treatment to identify the cause, complete CT or magnetic resonance examination can help to identify the cause of the disease, intravenous mannitol, glycerol fructose can temporarily help to reduce intracranial pressure.
