What happens to your body in a coma?
Comas should not be mistaken for sleep, despite the word's origin from the Greek term for deep sleep, "Koma." Comas are a form of unconsciousness that differs greatly from sleep, rendering individuals unable to respond to external stimuli. Even if you were to blast the loudest, most intense death metal music right next to someone in a coma, it would have no effect other than irritating the neighbors. In fact, you could even inflict physical harm on a comatose person, and they would remain completely unaware and unresponsive. In the past, this lack of response was sometimes seen as an opportunity for "treatment," with doctors attempting various methods to shock patients back into consciousness. These methods ranged from exposing the body to flames, drastically lowering body temperature with ice, to even bloodletting from the head. There were even cases where doctors believed that emptying the stomach completely would force the patient to wake up due to hunger. It seems that doctors were willing to try anything and everything, including the kitchen sink, to solve the problem. Comas can occur as a result of severe trauma or as a deliberate medical treatment. They are often triggered by traumatic head injuries, as the brain shuts down to focus on self-repair. However, comas can also be caused by stroke, brain tumors, drug or alcohol abuse, or certain illnesses such as diabetes or infections. Typically, comas last only a few weeks. However, if the coma persists beyond this period, the patient may enter a persistent vegetative state, greatly reducing their chances of recovery. In some cases, individuals who do recover from a coma may experience major or minor disabilities, including speech impediments, mental retardation, or difficulties with coordination. Medically induced comas are utilized in cases where patients face a high risk of brain injury, whether it be due to physical trauma, drug overdoses, or diseases. The main objective is to safeguard and regulate the pressure dynamics within the brain. In instances of injury or illness, the brain may swell and exert pressure against the skull, leading to oxygen deprivation in certain areas of the brain. By inducing a coma, the electrical activity of the brain is decreased and its metabolism is slowed down, thereby reducing swelling and inflammation. Various types of comas exist, each distinct from the others. A vegetative state indicates that the individual's body may exhibit physical movements like grunts or yawns, yet does not respond to external stimuli. These movements are purely involuntary, and witnessing a loved one's body yawn can unfortunately give rise to false hope. In reality, the brain remains inactive and functions only at the most basic levels. Conversely, catatonia involves a complete absence of movement or response of any kind- as the term suggests. Catatonic patients often require assistance from machines to facilitate breathing and potentially even heart function. Brain death signifies the complete destruction of higher brain functions, with the brain solely carrying out autonomic functions such as breathing and swallowing which are instinctual. A person declared brain dead has no possibility of recovery, typically resulting from severe physical trauma or illness. While a stupor is not technically classified as a form of coma, it is sometimes colloquially referred to as one. Individuals in a stupor may be roused, albeit with significant effort. They may easily slip back into a deep unconscious state, but more often than not, they will regain consciousness on their own. The concern arises if they descend so deeply into unconsciousness that their autonomic functions are compromised. During a coma, the brain exhibits no awareness or cognitive processing, and is entirely unresponsive to external stimuli. It is as if the brain has completely shut down or is undergoing a reboot similar to a computer. In less severe cases, the body will continue to perform basic functions such as breathing and pumping blood. In some instances, patients may even cough as the body tries to regain airflow when the airway is blocked. However, the brain appears to be unable to establish communication between the brain stem and the cerebrum, which is responsible for cognitive consciousness. This lack of communication occurs due to the reticular activating system. The coma state remains largely mysterious to doctors, and there is still much that is unknown about it. In 2013, doctors treating an epileptic man in a coma were surprised to discover brain activity in the hippocampus. This region of the brain is believed to be associated with emotions, memory, and the autonomic nervous system. It is possible that the unconscious person may experience memories but little else. The doctors conducted similar experiments on cats under general anesthesia and gained valuable knowledge that could potentially lead to the reversal of comas. However, it is important to note that the presence of brain activity does not indicate awareness or the ability to communicate about one's condition. Nevertheless, it does provide strong evidence that the brain takes actions to repair and protect itself while in a comatose state. The rest of the body generally remains unaffected by the coma, as functions like breathing and heartbeating are controlled by the passive nervous system. Coma patients often require intravenous feeding and hydration, as well as intubation to maintain a clear airway. Some patients may still retain the reflexes to swallow. However, the most common issue faced by coma patients is muscle atrophy, which occurs due to prolonged periods of inactivity. You do not have to be in a coma for this to occur; if you have spent several weeks as a couch potato, you have likely experienced muscle weakness due to lack of exercise. Simply taking a walk once a day can prevent muscle atrophy. Bedsores are a serious concern for coma patients, also known as pressure ulcers. These are common for individuals who are bedridden, immobile, or lack the ability to feel pain. They occur in areas of the skin under pressure from prolonged bed rest, sitting, or wearing a tight cast. If left untreated, bedsores can lead to infection and become deep, extending into the muscle or bone. They are slow to heal and may require surgery. Despite common misconceptions, most coma patients recover within a few weeks with some level of mental capacity. Ongoing research and advancements in treatment are improving our understanding of comas, as seen in a case where a 35-year-old man in a vegetative state for 15 years was able to achieve "minimal consciousness" through vagus nerve stimulation. This nerve is one of the largest in the body, connecting directly to the heart, lungs, upper digestive tract, and other vital organs. During his unconscious state, medical professionals successfully guided his eye movements towards objects, eliciting expressions of astonishment on his face. Regrettably, he remained unable to communicate verbally or exhibit any signs of higher cognitive function. Despite this significant progress, doctors caution that recovery from comas varies greatly among individuals, and what proves effective for one patient may not necessarily yield the same results for others.
