When the average cerebrospinal fluid pressure of an adult measured in the lateral position exceeds 1.96 kPa (equivalent to 200 mmH2O), it is considered as increased intracranial pressure. Intracranial hypertension is a common neurological syndrome caused by a variety of reasons that increase the total volume of cranial contents, or congenital malformations that cause the cranial cavity to be narrow, resulting in increased intracranial pressure and exceeding its compensatory range. It is also called increased intracranial pressure. Increased intracranial pressure can cause a series of physiological disorders and pathological changes. If not diagnosed and treated in time, patients often die from brain herniation.
