Someone who is in a coma is unconscious and will not respond to voices, other sounds, or any sort of activity going on nearby. The person is still alive, but the brain is functioning at its lowest stage of alertness.
Someone who is in a coma is unconscious and has minimal brain activity. They're alive, but can't be woken up and show no signs of being aware. The person's eyes will be closed and they'll appear to be unresponsive to their environment.
A coma patient can be called as living because apart from the external environment he or she can breathe can reproduce as well as the heart beat also works..so all the life processes are working ....so yeah more chances to living...
Coma patients might feel pleasure and pain like the rest of us.
Coma is a state of consciousness that is similar to deep sleep, except no amount of external stimuli (such as sounds or sensations) can prompt the brain to become awake and alert. A person in a coma can't even respond to pain. A wide range of illnesses, conditions and events can cause coma.
A: Many people who have woken up from comas have reported having dreams in which they saw something from the outer world. Others have had dreams that seemed to stretch on and on.
A person may appear fine, but will not able to speak or respond to commands. Spontaneous movements may occur, and the eyes may open in response to external stimuli. Individuals may even occasionally grimace, cry, or laugh.
Someone who is in a coma is unconscious and has minimal brain activity. They're alive but can't be woken up and show no signs of awareness. The person's eyes will be closed and they'll appear to be unresponsive to their environment.
People in a coma are completely unresponsive. They do not move, do not react to light or sound and cannot feel pain.
Most people do come out of a coma
In some rare cases, a person might stay in a coma for several weeks, months or even years. Depending on what caused the person to go into a coma, some patients are able to return to their normal lives after leaving the hospital.
But without a ventilator to keep blood and oxygen moving, this beating would stop very quickly, usually in less than an hour, Greene-Chandos said. With just a ventilator, some biological processes — including kidney and gastric functions — can continue for about a week, Greene-Chandos said.
A coma doesn't usually last longer than several weeks. People who are unconscious for a longer time might transition to a lasting vegetative state, known as a persistent vegetative state, or brain death.
Roving eye movements are typically slow, horizontal, bilateral conjugate deviations that are normally seen in light sleep. In comatose patients, these presence of these eye movements suggests a supranuclear (i.e., cortical) etiology (e.g., toxic-metabolic or other bilateral hemispheric etiologies).
Hence, they are neither awake nor aware. Coma is a time-limited condition (it usually does not last longer than a few weeks) leading either to brain death (i.e., permanent loss of brainstem functions), a VS/UWS or the recovery of consciousness.
She went under general anesthetic and never came out. Dubbed the "sleeping beauty," Esposito stayed in a coma for 37 years and 111 days before succumbing in 1978 — the longest-ever coma, according to Guinness World Records.
Annie Shapiro (1913–2003) was a Canadian apron shop owner who was in a coma for 29 years because of a massive stroke and suddenly awakened in 1992. Apart from the patients in the true story Awakenings, Shapiro was the longest a person has been in a coma like state and woken up.
There are a number of criteria for diagnosing brain death.
a person must be unconscious and fail to respond to outside stimulation. a person's heartbeat and breathing can only be maintained using a ventilator. there must be clear evidence that serious brain damage has occurred and it cannot be cured.
Being comatose is being in a coma, unconscious and unable to communicate, often for long periods of time. A bad illness or unexpected accident or injury — especially to the head — can make you comatose and trapped inside a body that isn't working.
Severe brain injury is usually defined as being a condition where the patient has been in an unconscious state for 6 hours or more, or a post-traumatic amnesia of 24 hours or more. These patients are likely to be hospitalised and receive rehabilitation once the acute phase has passed.
Use objects with pleasant tactile sensations and different textures such as soft toys, silk scarves or books. Put a bunch of flowers in the person's room or spray their favourite perfume.
Some examples of early responses to watch for are: Localized response: These are appropriate movements by the patient in response to sound, touch, or sight. Turning toward a sound, pulling away from something uncomfortable, or following movement with the eyes are examples.
Stage 4: Higher Level of Responsiveness
A patient at this stage may not be fully aware of their limitations. Family and friends might notice some personality changes at this stage as well. The recovery process is different for everyone, and some patients could stay in one stage longer than the other.
People in a vegetative state can open their eyes, but they cannot speak or do things that require thought or conscious intention, and they have no awareness of themselves or their environment.
the cellular mechanism for ageing has been associated with progressive shortening of telomere length on the ends of each chromosome with each cell cycle.. in the contect of this, a coma wouldnt necessarily keep you young, but you would age just the same.
