What is the difference between brain death and a vegetative state?

Brain death and vegetative states are not the same concept, and the fundamental difference between the two is that vegetative states have spontaneous respiration, while brain death does not. The so-called vegetative state refers to a pathological state in which the function of the cerebral cortex, a higher part of the nerve center, is lost, and the patient is in a state of consciousness disorder or coma, while the functions of the subcortical center (subcortical nucleus and brainstem, etc.) such as respiration, circulation, body temperature regulation, digestion and absorption, secretion and excretion, metabolism and so on still exist. Patients dealing with vegetative states may survive for a long time with proper care.

Brain-dead EEG is a straight line, and patients in vegetative states sometimes have a certain amount of consciousness in the brain, but the upward reticular activation system is turned off, just like a computer crash that cannot be restarted. <>

Although the vegetative person has lost consciousness and is in a deep coma, the basic physiological functions of his body are continuing, and he can still breathe without help, which is the so-called spontaneous breathing, and some reflexes are still present, and even in the rhythm of sleep awakening, if you are lucky, you can wake up in a certain situation. As for brain death, it means that he has wandered under the stars of another world, as Bilbo said when he stepped on the white ship bound for Valinor. Brain death must be distinguished from a "vegetative state" or a "vegetative state," which refers to a state in which the cerebral cortex is severely impaired leading to loss of subjective consciousness, but the patient retains the function of the subcortical center.

Among the many differences between vegetative state and brain death, the most fundamental difference is that patients in vegetative state throw to maintain spontaneous breathing function. <>

This is a blockage of the meridians, which can be repaired with acid-base flat DDS technology, which opens up the meridians and activates the cells.

Science, popular science, brain death, vegetative person, human body.

Brain death is defined as a criterion for declaring death based on the permanent loss of function of the central nervous system in or above the brainstem. Brain death is different from "vegetative", "vegetative" brainstem function is normal, coma is only due to severe damage to the cerebral cortex or in a state of sudden inhibition, the patient can have spontaneous breathing, heartbeat and brainstem response, while brain death has no spontaneous breathing, is permanent and irreversible. Brain death is death in the literal sense of the word

After brain death, the brain no longer emits radio waves, but vegetative people have brain waves, but they are weaker. Brain death is death in the true sense of the word.

A vegetative person is a person who is still alive but is in a coma and cannot move his limbs, and brain death is real death. So it's completely different.

According to my understanding, it's pretty much the same, but the vegetative person is in a state of suspended animation, and there is a possibility of awakening.

Brain death is also a kind of vegetative person, and it is more serious than a vegetative person, which means that the spirit and consciousness are completely absent and cannot be recovered!

Vegetative people can usually sense things around them, the brain consciousness exists, and the mental nerves are not innervated by the brain. Confusion with a chance to return to normal.

In some countries, death and brain death mean the same thing, but in China, death is based on the heart stopping beating, and cardiac arrest is generally later than brain death, and some countries like the United States use brain death as the standard of death to keep organs fresh for organ transplantation. Vegetative people still have the possibility of awakening, but brain death is not.

brain death; There is no spontaneous breathing, cerebral function is lost, heart function is normal, blood circulation is normal, and life is maintained by instruments and drugs, at this time the person enters a vegetative state.

The difference is in the presence or absence of brainstem function.

Brain death: An irreversible state of loss of function of the whole brain, including the brainstem.

Vegetative: Coma is simply due to severe damage to the cerebral cortex or being in a state of sudden inhibition.

Vegetative people are also known as phytoplasmic states and irreversible coma.

It is a serious impairment of the function of the cerebral cortex, and the victim is in an irreversible deep coma and loses consciousness and activity, but the subcortical center can maintain spontaneous breathing movements and heartbeat, this state is called "vegetative state", and the patient in this state is called "vegetative person", which is a special human state similar to the state of plant existence.

With the exception of some instinctive nerve reflexes and the ability to metabolize matter and energy, cognitive abilities (including the perception of one's own existence) have been completely lost, and there is no active activity.
