An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead. A determination of death must be made in accordance with accepted medical standards.
If a person experiences a complete cessation of brain activity and is considered brain dead, they can survive for a limited time, typically a few days to weeks, depending on the functioning of other organs and medical interventions. Life support systems may prolong this period, but without brain activity, the prognosis is grim. Ultimately, the individual will not recover, as brain death is irreversible.
The medical term is electroencephalograph (EEG), which is a device used to measure the electrical activity of the brain.
Death is defined as the cessation of all vital functions of the body including the heartbeat, brain activity (including the brain stem), and breathing.

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.

A body is typically declared dead when there is an irreversible cessation of all biological functions that sustain life, including the absence of heartbeat and breathing. In medical settings, this is often confirmed through clinical assessments, such as checking for pulse and responsiveness. Additionally, in some cases, brain death can be declared when there is a total and irreversible loss of brain function, even if some bodily functions may continue with medical intervention. This determination is made by qualified medical professionals following established protocols.
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.
Life support is used for individuals who are brain dead to maintain organ function and preserve bodily systems for potential organ donation. Although brain death signifies the irreversible cessation of all brain activity, life support can keep vital organs functioning temporarily. This is often crucial for ethical and medical reasons, allowing for the possibility of saving other lives through organ transplantation.
Several factors can stop the brain from functioning, such as severe head trauma, lack of oxygen, stroke, brain tumors, infections, and certain medications or substances that affect brain function. These conditions can disrupt the brain's normal functioning and lead to various impairments or even complete cessation of brain activity.
Brain death is considered a legal and medical definition of death in many countries. It occurs when there is irreversible loss of all brain function, including activity of the brainstem. While the heart may still be beating with the help of life support, the individual is considered dead as there is no possibility of recovery.
