There is very little research on just how long the body of a brain-dead person can be maintained. The discussion of brain death dates back to the 1950s in France with six patients who were kept "alive" for between two and 26 days without blood flow to the brain.

If untreated, life-threatening coma or respiratory failure could occur within 7 to 10 days and most will die within several months. Upon any lapse of treatment, classic MSUD can cause brain damage. People with the disease are particularly prone to crisis during illness, infection, fasting, or after surgery.

Medically speaking, most doctors agree that healthy humans can go up to eight weeks without food as long as they have water. People have gone longer and been fine, and people have starved to death in less time. Being strong and in good physical shape can help you survive longer, but so does having extra body fat.

Some of these patients never come back to normal life. They can neither he called living nor non-living or dead.

Biological Death versus Clinical Death The first stage is called Clinical Death. Clinical death is not necessarily permanent. An individual's brain can stay alive for about 4-6 minutes after breathing and heartbeat have stopped.

The brain can survive for up to about six minutes after the heart stops. The reason to learn cardiopulmonary resuscitation (CPR) is that if CPR is started within six minutes of cardiac arrest, the brain may survive the lack of oxygen. After about six minutes without CPR, however, the brain begins to die.

When someone is choking with a completely blocked airway, no oxygen can enter the lungs. The brain is extremely sensitive to this lack of oxygen and begins to die within four to six minutes. It is during this time that first aid must take place. Irreversible brain death occurs in as little as 10 minutes.

Brain cells are very sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death.

Answer: The answer to this question depends on the person's condition. An old, frail or ill person who stops taking in calories and fluids may only linger for a few days, gradually falling deeper and deeper into sleep. A person whose body is stronger may take two or even three weeks to deteriorate to the point of coma.
