Brain edema manifestations

Brain edema performance? Brain edema is characterized by increased intracranial pressure, intracranial pressure increased refers to the pathological state, intracranial pressure more than 200 mm water column, often showing headache, vomiting, papilledema, so it is also the main manifestation of brain edema. The first, vascular brain edema: clinical most common, mainly caused by the destruction of the blood-brain barrier, mainly to increase the water content of brain tissue gap, mainly seen in brain injury, inflammation, stroke and brain tumors. The second, cytotoxic brain edema: mainly due to hypoxia, ischemia, poisoning and other reasons caused by damage to the cell membrane structure, water accumulation in the cells, mainly seen in asphyxia, carbon monoxide poisoning, uremia, hepatic encephalopathy, drugs and food poisoning and other reasons. Third, intracranial space-occupying lesions, as well as intracranial blood volume increase, cerebrospinal fluid increase, such as hydrocephalus, which can cause intracranial pressure increased.
