High intracranial pressure syndrome

High intracranial pressure syndrome is a common neurological syndrome, which means that the pressure in the cranial cavity is increased in the brain. Generally, the intracranial pressure is usually expressed by the cerebrospinal fluid pressure in the subarachnoid space. It is clinically characterized by headache, vomiting and papillary edema. Normal intracranial refers to the pressure measured by lumbar puncture in a normal person when lying horizontally: 0.78-1.76kPa (80-180mmH2O) in normal adults and 0.49-0.98kPa (50-100mmH2O) in children. If the pressure exceeds 1.96 kPa (200mmH2O), the intracranial pressure is generally considered to be increased.
