That means while the patient is still breathing with the help of a ventilator and their heart is beating, their brain has called it quits. This is a situation that can occur after a patient has been placed on life support, and is not the same as a coma which is an unconscious state a person can come out of , notes the Better Health Channel in Australia.
Here are six signs of brain death…. That means to get a diagnosis of brain death, doctors will often see if a patient can breathe unassisted, notes the National Kidney Foundation. During the tests to determine brain dead status, the patient is placed on a ventilator and may be given medications to maintain blood pressure and other bodily functions.
It mentions a few reflexes related to the eyes that will be absent if a person is clinically brain dead. The normal ways a person may recoil or verbalize pain are absent when they have experienced brain death. However, ScienceDaily posted an interesting although unrelated article that states a patient may still have spontaneous movements following a brain death diagnosis. A person in a vegetative state is alive and may recover to some degree, given time.
Brain death means the person has died. This gives the illusion that the person is still alive. Family members may hold a false hope that the person is just comatose and could wake up with time or treatment. It is important for the medical staff members to fully explain that brain death is final, and that the person is dead and has no chance of ever regaining consciousness again.
In some cases, a person who is brain dead may be a candidate for organ donation. If the person was a registered organ donor, or if their family knew of their wish to be an organ donor, their death is declared, but the ventilator is left on.
Drugs that help preserve the internal organs are still given. The dead person then undergoes an operation to remove viable organs such as kidneys. After the operation is complete, the ventilator is switched off. Funeral arrangements can then be made by the family. This page has been produced in consultation with and approved by:.

These physical functions may be present in a person who is brain dead because the physical damage is actually hidden in the brain, rather than visible on the body.
Brain cells do not effectively regenerate. This makes it difficult for the brain to recover from injury. Serious brain damage can occur due to a stroke, heart attack, or head trauma.
When brain cells undergo permanent damage, they cannot be replaced. Major loss of brain function results in brain death. Brain death means that a qualified physician, typically a neurologist, did an extensive physical examination and documented brain death criteria.
The physical examination is done to determine the level of responsiveness. If the examination shows a lack of responsiveness, the physical exam would proceed to check for certain reflexes. Someone who is brain dead will not have any brainstem reflexes. For example, a person in a coma who is not brain dead would blink or move their head if their eye is irritated with a piece of a cotton ball. A person who is brain dead cannot blink, flinch or try to move away if the doctor touches their eye with a fuzzy piece of cotton.
Therefore, if there is no blink reflexes, that implies that the brainstem is not functioning properly. Another type of physical testing is the cold caloric.
