It's not just high intracranial pressure that's dangerous for our body. Intracranial pressure, or intracranial hypertension, is almost more serious🧠 This pathology is on the list of the most common diseases of the brain and is a hazardous disease that has a devastating effect on its structures. Pressure on the brain is exerted by the cerebrospinal fluid (cerebrospinal fluid) inside the ventricles of the brain. Intracranial hypertension develops due to a variety of causes. The most obvious example is a brain tumor. It displaces the hemispheres, thereby "squeezing" the cavities of the ventricles and the cerebrospinal fluid inside them. This causes an increase in pressure inside the ventricles.
