Total loss of brain function is known as what?

Explanation:
Brain death is the term for total loss of brain function. It means irreversible cessation of all brain activity, including the brainstem. When this occurs, the person is legally dead even if a ventilator is keeping the heart beating. There is no consciousness, no purposeful response to stimuli, and no brainstem reflexes; breathing cannot occur on its own, which is why apnea testing is used in assessments. This state is different from coma or a persistent vegetative state, where some brain activity or wakefulness may remain. So the correct term for total loss of brain function is brain death.
