law on the books (opens in new tab) since 1981, it is considered a true death, just as final as death when the heart stops. Until the 1950s, the distinction of brain death didn't really exist, because when the heart stopped, the oxygen-starved brain died within a few minutes. Conversely, any direct injury to the human brain severe enough to damage the regions controlling breathing inevitably led the heart and respiration to stop. But the advent of cardiopulmonary resuscitation (CPR), artificial ventilation, and extracorporeal membrane oxygenation (ECMO), which uses a heart-lung machine to oxygenate the blood outside the body, broke that inevitable link.

Moreover, those individuals who respond well to this treatment show a greater increase in connectivity than those who don’t.

We found that if this treatment leads to an increase in brain connectivity, it is also effective in tackling depression symptoms.  The rules around diagnosing brain death can differ from place to place, and there are sometimes controversies when a patient's family disagrees with a doctor's assessment that their relative's condition is irreversible or when medical error yields a misdiagnosis (opens in new tab). There are also debates about whether brain death should include more tests or criteria.” Graph showing the increase in the number of connections pre- and post-treatment for clinical depression. Finally, some faith traditions also object to brain death on religious grounds.

But at its core, brain death is defined by doctors as the irreversible loss of all brain function, including in the brain stem. Participants’ brains were scanned using an MRI scanner that had been set up to identify which parts of the brain were communicating with other parts as a way of measuring the level of connections within the brain.

  How does the brain die? Brain death, also known as death by neurological criteria, is a relatively rare way to die, said Dr. Panayiotis Varelas,  chair of neurology at Albany Medical College.

After treatment, the study participants were then rescanned using MRI to measure the number of brain connections. But it can happen in cases of severe brain injury, either due to brain trauma or an extended lack of oxygen. In the face of trauma or a lack of oxygen, the brain cells begin to die, Varelas told Live Science.

Professor Repple (now Professor of Predictive Psychiatry at the University of Frankfurt) said: “We found that treatment for depression changed the infrastructure of the brain, which goes against previous expectations. This mass die-off causes inflammation (opens in new tab) and swelling, locking the brain into a vicious feedback loop: Damage leads to swelling, which leads to more damage as delicate nerve cells are pressed against the hard case of the skull.

The brain stem gets squeezed through the foramen magnum, the hole at the base of the skull where the spinal cord connects to the brain. Moreover, those who showed the most response to treatment developed a greater number of new connections than those who showed little response.This damages the regions that control breathing and the heartbeat.

Meanwhile, Varelas said, the increasing pressure inside the skull makes it increasingly harder for blood to reach the brain. “We found these changes took place over a period of only around 6 weeks, we were surprised at the speed of response.

Once a patient is far along enough on this spiral, brain death is inevitable. In most cases, death of the rest of the body will follow, even if a patient's other organs are still getting oxygen through a ventilator. “The results align very much with our current belief that the brain has much more flexibility in adaptation over (even short) time than was previously thought.

The other organs stop responding to medical treatment, Varelas said.   "The whole body shuts down, a sign of how powerful the control of the brain is to the rest of the body," he said.

Moreover, the next question is whether different treatments have the possibility to specifically change targeted brain networks or vice versa whether we can use the disturbances in brain-networks as measured in the present study to choose which therapy will be helpful. This can allow for the removal of artificial life support and futile treatment, or enable organ donation in some cases. An experienced neurologist or neurosurgeon must conduct an examination.

First these results should be replicated in independent samples which hopefully is going to happen soon. To get to that point, a few key criteria must be met: There must be a known cause for the patient's condition, consistent with a catastrophic injury to the whole brain, and the patient's unresponsive state must not be due to side effects of medication, sedation or some other potentially reversible cause, according to a 2022 article in the Journal of Intensive Care.

If these prerequisites are met, the physician can conduct a clinical exam testing for reflexes that depend on a functioning brain stem.” This is an independent comment, Dr. There are multiple reflexes tested, such as whether the pupils respond to light and whether the eyelid closes when something touches the surface of the patient's eye.

Another test involves flushing the inner ear with cold water. This work was presented at the 35 th European College of Neuropsychopharmacology annual conference, which took place in Vienna. In a patient with a functioning brain stem, the eye will move toward that ear as part of a reflex involving the body's sense of balance.

There are also tests involving the gag reflex and other automatic muscle movements..  If the patient shows no signs of brain stem reflexes, doctors conduct a final test called the apnea test: They remove the patient from mechanical ventilation to see if the person starts breathing spontaneously. A brain-dead patient cannot breath on their own.  Related content— Scientists revived the cells of pigs an hour after death, a potential organ transplant breakthrough — Can minds persist when they are cut off from the world? — What happens to your body when you're an organ donor?  "It's a very, very difficult moment for the families and for us physicians," Varelas said.

Brain deaths often occur after sudden medical events or accidents, so the loss of the loved one is often unexpected and extremely difficult to process, he said.   Doctors can try to reduce swelling in an injured brain and prevent brain death, Varelas said, and they treat patients as aggressively as they can until brain death is declared.

But once full brain function is lost, there is no hope for repair. "That's why they call it the coma dépassé, or 'beyond the coma,'" Varelas said, referring to the name given to the condition by two French neurologists in 1959."Here we are talking about the loss of function of the entire brain."
