Brain death can you recover

The discussion of brain death dates back to the s in France with six patients who were kept "alive" for between two and 26 days without blood flow to the brain. This generated the idea that "perhaps there's a second way to die, because these patients will eventually die," Greene-Chandos said.

Previously, a person was considered dead only when their heartbeat and breathing stopped. Today, with ventilators, blood-pressure augmentation and hormones, the body of a brain-dead person could, in theory, be kept functioning for a long time, perhaps indefinitely, Greene-Chandos said. But with time, Greene-Chandos added, the body of a brain-dead person becomes increasingly difficult to maintain, and the tissue is at high risk for infection.

Terri Schiavo's family, who fought to keep their brain-damaged daughter on life support for 15 years, has said they are trying to help move Jahi to another facility for long-term support. Unlike Jahi, Terri Schiavo was not brain dead, but in a vegetative state in which she had some brain activity.

The extracted bioactive components, mostly microRNAs and proteins, can reprogram damaged cells into a stem cell-like state, wrote the team in a patent.

Our core focus is on these morphogenic extracts, explained Pastor. That said, relatively little has been published on the lead chemical extract, a mix of bioactive molecules with the esoteric name BQ-A, in animal models of brain death.

The problem is that such models are few and far between, and some of them are quite exotic, like poisoning pigs with carbon monoxide, explained Pastor. We steered away from these models and instead focused on traumatic brain injury and spinal cord injury models in our preliminary studies, he said.

The current trial will be the first that directly tests the power of these extracts to help reboot the human brain. Pastor stresses that the study is designed to look at very basic brain stem function after treatment — an electrical whisper here, a puff of neurotransmitter there. In addition to cell-based therapies, Bioquark also plans on using brain stimulation techniques to supplement BQ-A. These treatments, including median nerve stimulation and transcranial laser stimulation , are often used to treat cases of coma and other severe disorders of consciousness with varying degrees of success.

Why use such a big combination of different techniques? The current big pharma model of disease intervention has two severe flaws as I see it, explains Pastor. One is the heavy focus on treating late-stage symptoms rather than the initial cause. Another is the reductionist approach to reduce any disease to a single cause, and therefore, a single drug solution.

But looking ahead, if the treatment works, we may run into the thorny philosophical question of personal identity. As bioethicist Dr.

By studying the extreme end of brain damage, Pastor believes that the team will gain unique insights into the workings of a dying brain — insights that may ultimately help a range of degenerating central nervous system conditions.

When attending physicians suspect a patient is brain-dead, they may opt to call a consultant—a Johns Hopkins neurologist, neurosurgeon or critical care specialist with experience and training in two different, but related, areas: the techniques used to determine death, and communicating the nuances of the difficult situation with primary care teams and family members.

The consultant performs a full neurological examination to determine if there are any signs of brain or brainstem function. This includes assessing the drive to take a breath, determining whether pupils react to light, and swabbing the back of the throat to elicit a gag reflex. The neurological examination must be repeated at least once after a minimum interval of six hours, to ensure that brain function is not temporarily suppressed by factors such as high doses of narcotics or intense cold.

The support team helps those consultants by providing guidance and answering questions. Because of that support, brain death determinations take less time than in the past. A brain death diagnosis is nearly always confusing and overwhelming to family members. In a few states, though not Maryland, doctors must accommodate the preferences of families who refuse to accept the diagnosis for religious reasons.

That happened in , when the parents of Jahi McMath moved theyear-old from a California hospital to one in New Jersey after a brain death diagnosis following tonsillectomy complications.
