why does cerebral hemorrhage cause coma?

why does cerebral hemorrhage cause coma? first, we understand what is cerebral hemorrhage? intracerebral hemorrhage (ich) refers to primary non-traumatic intraparenchymal hemorrhage, also known as spontaneous cerebral hemorrhage, accounting for 20% to 30% of acute cerebrovascular diseases. about 80% of hemorrhages occur in the cerebral hemispheres, and about 20% of hemorrhages occur in the brainstem and cerebellum.

what is the incidence of cerebral hemorrhage in the population? according to the chinese cerebral hemorrhage diagnosis and treatment guidelines (2014 edition), the incidence rate of cerebral hemorrhage in my country is 12 to 15 cases per 100,000 people every year. cerebral hemorrhage is an acute cerebral hemorrhage. vascular disease has the highest mortality rate. it often occurs in patients over 50 years old, and most people have hypertension.

the coma of patients with cerebral hemorrhage is mainly caused by relatively large damage to the nerves, which leads to coma. the preservation of the human body in a conscious state first depends on two aspects:

first, the reticular nerve fiber center in the brainstem can remain in an awake state, which means it can do the most basic physiological activities, such as eating, defecation, breathing, etc.

secondly, the brain as a whole will maintain a high-level life support. for example, what kind of food to eat, whether it is salty or light, and how to urinate and defecate are all controlled consciously, etc. therefore, if the amount of cerebral hemorrhage is relatively large and various nerves are damaged, it will cause the person not to eat, not knowing how to eat, etc., and then gradually become serious, leading to coma.
