Increased intracranial pressure in the elderly

Normal people have a certain amount of pressure in the skull, called intracranial pressure (referred to as cranial pressure), which usually refers to the pressure measured by a lumbar puncture connected to a certain inner diameter tube in a horizontally lying position and the body is relaxed. The ground is called cerebrospinal fluid pressure. Normal adults with an increase in intracranial pressure above 1.96kPa (200mmH2O). Elevated intracranial pressure in the elderly occurs in patients with malignant tumors, most of which are caused by intracranial metastases.
