Vegetative is not brain death, generally speaking, vegetative refers to the patient’s brain hemisphere function is seriously damaged but the brain stem function is relatively retained, while brain death is the total loss of brain and brain stem function. Many causes of vegetative patients can be understood as more serious brain damage, patients do not have any cognitive and language ability to themselves and the outside world, others can not communicate with the patient, and their own pain and other sensations are also very weak, sometimes even if the eyes can see, but also can not move or change the position by themselves, but the patient can have a sleep-wake cycle. Brain death is the loss of all brain functions and is characterized by a deep coma, in which the patient does not breathe on his own, all brainstem reflexes are absent, and he is unresponsive to external stimuli. Some long-term coma patients still have the possibility of awakening, it is recommended to go to a regular hospital to consult the doctor, under the guidance of the doctor to cooperate with the treatment.
