At what point are you brain dead?

When someone is brain dead, it means that the brain is no longer working in any capacity and never will again. Other organs, such as the heart, kidneys or liver, can still work for a short time if the breathing machine is left in place, but when brain death is declared, it means the person has died.

Can you recover after being declared brain dead?

If the clinical situation and the tests have led to the determination of brain death, then this means the patient cannot recover; brain death is death, which is irreversible. Keeping a body on a ventilator after brain death has been declared properly will never result in recovery.

Can brain dead patients wake up?

It can be confusing to be told someone has brain death, because their life support machine will keep their heart beating and their chest will still rise and fall with every breath from the ventilator. But they will not ever regain consciousness or start breathing on their own again.

What test is done to check for brain activity?

They must also rule out any chance that the person might recover brain function.
