What is the difference between a coma and brain dead?

Can brain activity come back?
No. The brain will never recover when it dies. Since the patient has already been declared dead, removing the machine (which is artificially pumping air into the lungs) cannot cause further harm or death.
How long can someone be on life support with no brain activity?
If a person is in a permanent vegetative state but not brain-dead, their life support likely consists of fluids and nutrition. If these are stopped, it may take anywhere from a few hours to several days for the person’s vital organs to shut down completely.
