(And ask questions? - sorry, I couldn't resist.) Seriously: brain death (originally a legal term) by definition means, an irreversible, final (and terminal) cessation of all brain activity. Including not only the neocortex, but the lower regions as well. It is, however, easily confused with various stages of coma.

What is the most rapid mechanism of death?
There is some legal dispute as to the definition of "death." This answer focuses on the anatomical definition of brain death: Death has occurred once the brain ceases to generate any neuronal activity. The fastest mechanism of death, then, would be any injury that destroys the critical centers of the brain. The brainstem plays a significant role in maintaining consciousness and controlling cardiac and respiratory functions, so devastating injury to the brain stem could cause immediate death. Any global injury to the brain, such as diffuse axonal injury, can cause a coma or death; the most severe of these injuries can cause immediate death. Of course, the most rapid mechanism of death would be the immediate and total destruction of the critical life tissues. For example, a large proximal explosion could immediately destroy the entire brain, thus causing instantaneous death.
What organ death occurs when there is an absence of heartbeat with no chance of resurrection?
If there is an absence of a heartbeat with no chance of resurrection, it typically results in brain death. This means that the brain has permanently stopped functioning and cannot be revived, leading to the irreversible cessation of all brain activity.
What is the leading cause of death-related traumatic brain injury?
The leading cause of death-related traumatic brain injury is motor vehicle accidents, followed by falls, assaults, and other forms of blunt force trauma. These incidents can result in severe head injuries that lead to brain damage or swelling, ultimately causing death.
What is the sudden death of a brain cell when their blood supply is interrupted is called?
The sudden death of a brain cell when its blood supply is interrupted is called a stroke. Strokes can result from either a blockage of blood flow (ischemic stroke) or bleeding in the brain (hemorrhagic stroke), leading to brain cell damage and potentially permanent neurological deficits.
What are the key differences between being in a brain dead, vegetative state, and coma, and how do these states impact a person's level of consciousness and brain function?
Brain death is the complete and irreversible loss of brain function, including the brainstem. A person in a vegetative state has preserved brainstem function but no awareness of their surroundings. Coma is a state of unconsciousness where a person is unresponsive. Brain death results in no consciousness or brain function, while a vegetative state may have some basic functions. Coma is a temporary state of unconsciousness that may or may not lead to recovery.
Condition in which brain no longer functions?
When the brain no longer functions, it is typically referred to as brain death. Brain death is the irreversible loss of all brain function, including the brainstem, and is considered the legal and medical criteria for death in most countries.
When are you truly dead?
When all brain activity stops.
What is the meaning of brain death?
Brain death is the irreversible end of all brain activity. The term brain death should not be confused with a persistent vegetative state like many people tend to do.
When was Brain Death - EP - created?
Brain Death - EP - was created in 1986-08.
Condition in which the brain no longer functions?
brain death.
How are brain death and cardiac death different?
Brain death is the irreversible loss of all brain function, including the brain stem, resulting in the cessation of all neurological activity, whereas cardiac death is the irreversible stoppage of the heart, leading to the cessation of circulation and oxygen delivery to vital organs. Brain death is considered the legal and medical standard for determining death in many countries, while cardiac death is when the heart stops beating and cannot be restarted.
Is brain death not as final as cardiac death?
Brain death is considered legally and clinically irreversible, marking the complete and permanent loss of all brain function, including the brainstem. In contrast, cardiac death occurs when the heart stops beating and blood circulation ceases, but is often reversible in some medical scenarios. While both are considered forms of death, brain death is a more definitive end of all neurological activity, whereas cardiac death can sometimes be resuscitated. Therefore, brain death is generally regarded as more final than cardiac death.

Which medical school wrote the standard definition of death in 1968?
In 1968, Harvard Medical School defined death as irreversible damage to the brain, or brain death.
What was johnnie cochran's cause of death?
A brain tumour.
