What are the consequences for an individual when their brain becomes dead?

When a person is declared brain dead, it signifies a complete and irreversible loss of all brain function, including consciousness and the ability to breathe independently. In this state, the brain can no longer control vital bodily functions such as heart rate, blood pressure, and temperature regulation. Despite the appearance of life due to the functioning of other organs, the individual is considered legally and medically deceased.

Life support may maintain the body’s circulation and organ function temporarily, but ultimately, the absence of brain activity means the person cannot recover. Decisions regarding organ donation or withdrawal of life support are often made in such cases, respecting the individual’s prior wishes or those of their family. Brain death represents the end stage of irreversible neurological damage, leading to the cessation of all bodily functions and the inevitability of death.
