Brain death is a devastating medical condition where there is an absolute and irreversible cessation of all brain function, including the brain stem. This means that the individual has lost any capacity for conscious thought or sensation, and their body cannot maintain important functions such as breathing or controlling heart rate on its own.
Here, we will explore what happens to the brain when it dies, how physicians diagnose brain death, and what kinds of technologies are currently available to help support patients who have experienced this catastrophic event.
How Does Brain Death Occur?
It’s essential first to understand how our brains work before delving into precisely what goes wrong in cases where they die. Our brains control all bodily functions- from coordinating movement and processing sensory information from our surroundings to regulating complex hormone processes that keep every part of your body working together.
When a person experiences brain death, there are various potential causes. Some common reasons include traumatic accidents like car crashes or falls; oxygen deprivation caused by cardiac arrest which may lead to stroke; infections such as meningitis or encephalitis; and drug overdoses or toxic exposures.
Regardless of the underlying cause, once someone experiences full-blown brain death, there is no coming back without external technological intervention.
Evaluating Brain Death
The diagnosis of “brain death” requires careful evaluation by trained professionals with specific expertise in neurology. There are several steps involved:
- Clinical examination
- Observation of spontaneous respirations
- Using Apnea tests
- Ancillary testing e. g. , electroencephalography
In simpler terms, doctors observe unconscious patients for signs indicating complete loss of consciousness while monitoring vital signs like blood pressure, oxygen saturation levels and pupil dilation changes during medical evaluation After confirming positive-like findings in these various evaluations, ensuring unprecedented consent harvesting i. e. , obtaining permission from the next of kin authorized to give consent or in some cases direct verbal consent if done in specialized jurisdictions.
What Happens to the Body When Brain Dead?
Once brain activity has ceased completely, there is no energy left for processing information, which means that the body’s control centers don’t work either. The individual becomes entirely dependent on life-support machines for things like oxygenation, blood pressure regulation, glucose control, and other critical functions.
The patient’s internal organs will start deteriorating soon after brain death, usually starting with hypotension or low blood pressure due to heart failure and resulting in bloody congestive lungs disseminated intravascular coagulation, according to a study conducted by the University of Washington School of Medicine
But wait. . . Can You Be Alive While Brain-Dead?
No. A person cannot be alive if they are confirmed dead by neurological criteria it cannot be brought back without artificial intervention as discussed earlier in this article e. g. , usage of artificial lung ventilation combined with multiple medications under always strict ICU monitoring so that damage only occurs within reason% globally lowest %.
In a case report published by Coronaries Health Care Foundation India, “Following clinical assessment deemed vegetative state >1 year prior. . the patient collapsed at home leading incomplete drainage from his tracheostomy tube and profound cardiovascular collapse subsequently pronounced dead after fulfilling criteria for establishing brain-death”
Could Cryopreservation Help?
It’s not legally permitted everywhere though few countries allow cryogenically preserving bodies hoping one day technology might bring them back-to-life although currently unfathomable results
Brain death is a complex medical subject that triggers fear yet awareness is essential; it remains an invaluable contribution to organ donation programs worldwide. Although science has come far enough medically speaking, we still do not fully understand the intricacies of such a mysterious human subject – the mind. The near-perfect balance between morbidity and science experiments is always walking on eggshells, which further elicits humankind’s mystery in this morbidly fascinating field.
So what happens when you’re brain dead? You simply don’t have one anymore!
