People who do wake up from a coma usually come round gradually. They may be very agitated and confused to begin with. Some people will make a full recovery and be completely unaffected by the coma. Others will have disabilities caused by the damage to their brain.
Whether they dream or not probably depends on the cause of the coma. If the visual cortex is badly damaged, visual dreams will be lost; if the auditory cortex is destroyed, then they will be unable to hear dreamed voices.
Typically, a coma does not last more than a few days or couple of weeks. 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.
Usually, coma patients have their eyes closed and cannot see what happens around them. But their ears keep receiving sounds from the environment. In some cases, the brains of coma patients can process sounds, for example the voice of someone speaking to them [2].
What Happens When Someone Is in a Coma? 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.
When your survivor emerges from her coma, she likely will have little or no short-term memory. She may be disoriented, agitated, angry, impulsive, or extremely emotional. She may be disinhibited, demonstrating a complete disregard for social conventions.
People in a coma will not age like conscious people living life. Muscles weaken & emaciate. The damaged part of the brain might deteriorate as a result of inflammation to the area.
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 case of pituitary coma with continuing menstruation is presented. This association is extremely rare, but a history of recent menstrual periods does not exclude advanced hypopituitarism from the differential diagnosis of severe hyponatraemia.
Even though those in a persistent vegetative state lose their higher brain functions, other key functions such as breathing and circulation remain relatively intact. Spontaneous movements may occur, and the eyes may open in response to external stimuli. Individuals may even occasionally grimace, cry, or laugh.
The different levels of coma. Recovery from coma. Post-traumatic amnesia. Vegetative state.
Someone who is in a coma is unconscious and has minimal brain activity. It is not possible to wake a coma patient using physical or auditory stimulation. 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.
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.
The soul of a person in a coma is still there, but mostly the vegetative part of it. You see, there are three aspects of a human soul—the vegetative, the sentient and the rational. The reason a person in a coma is still alive, though unconscious, is because of the vegetative part of the soul.
When Edwarda O'Bara died on 21 November 2012, she had survived 15,663 days (about 42 years) in a coma. Born in 1953, in Miami, Florida, O'Bara suffered a childhood history of diabetes, which she successfully managed with insulin.
Whyte says that coma patients who recover seldom complain of painful events or treatment during their comatose state, but this shouldn't be taken as evidence they never felt pain, because their memories are so impaired during this time that they wouldn't remember anyway even if they did feel pain.
Within six hours of coma onset those patients who show eye opening have almost a one in five chance of achieving a good recovery whereas those who do not have a one in 10 chance. Those who show no motor response have a 3% chance of making a good recovery whereas those who show flexion have a better than 15% chance.
It can result from injury to the brain, such as a severe head injury or stroke. A coma can also be caused by severe alcohol poisoning or a brain infection (encephalitis). People with diabetes could fall into a coma if their blood glucose levels suddenly became very low (hypoglycaemia) or very high (hyperglycaemia).
It often shows up suddenly, within hours or days. Some features of delirium include having trouble focusing (called inattention), sudden changes in behavior, and confusion. For most people, delirium doesn't last long – usually only a few days.
It can be like one long out-of-body experience.
Some survivors liken comas to an uncanny experience where you're wondering if you're the only person feeling what you're feeling. "If I had to compare it to real life," one writes, "I'd say it's like when you hear your name in a crowd.
Stage 4: Higher Level of Responsiveness
At this stage, a patient may be able to complete routine tasks without difficulty. However, they may still have issues with problem-solving, judgment, and decision-making.
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.
