As a medical professional with expertise in neurology, I can provide insight into the concept of brain death. Brain death is a legal and clinical definition that signifies the irreversible end of all functions of the entire brain, including the brainstem. When a person is declared brain dead, they are legally and clinically dead, even if their body may be kept alive through artificial means for a time.
The brain is the control center for the body, and when it ceases to function, the body's organs and systems can no longer be sustained. Without the brain's signals, the body cannot breathe on its own, maintain circulation, or perform any of the vital functions necessary for life. While the heart may continue to beat for a short time with the support of a ventilator, it is not a sign of life but rather a mechanical function.
