Vital medical facts about brain death diagnosis and the crucial difference between it and a coma.
Brain death is final death legally, religiously, and medically. It is NOT a "coma" and recovery is impossible.
It is the complete and irreversible cessation of all brain and brainstem functions. In this state, the brain loses control over breathing or heartbeat. The heart and lungs continue to function only through life support machines. Once machines are turned off, the heart stops immediately.
Brain cells do not regenerate; once they die, they cannot be brought back to life.
Present breathing and pulse are solely due to machines, not evidence of life.
| Feature | Coma | Brain Death |
|---|---|---|
| Brain Activity | Present but low | Completely Stopped |
| Breathing | Often spontaneous | Machine dependent |
| Recovery | Possible | Impossible (Legally Dead) |
Brain death is not declared lightly. It is diagnosed by a committee of specialized consultants (neurology, anesthesia, ICU) unrelated to the transplant team, ensuring absolute neutrality and precision.
Verifying absence of all brainstem reflexes.
Disconnecting the ventilator to check for spontaneous breathing attempts.
Such as EEG or Cerebral Angiography.
