Ambiguous death
Legal death
Brain death
Functional death

Brain death is defined as the complete and irreversible cessation of all brain activity, including the brain stem, which controls basic life functions such as breathing and circulation. In cases of brain death, a person is considered legally and clinically dead, even if other bodily functions might still be maintained through artificial support.

Since brain death is such a critical medical and ethical concept, it often becomes a point of confusion in discussions about life support and organ donation. It’s important for families to understand that brain death is distinct from conditions like coma or vegetative states, as it signifies that the individual has lost all neurological function permanently.
