They do not respond to touch, sound or pain, and cannot be awakened. Their brains often show no signs of the normal sleep-wakefulness cycle, which means they are unlikely to be dreaming. Yet many people who have recovered from comas report dreams into which something of the outside world penetrated.
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's ability to dream is most likely determined by the underlying medical condition that put them in a coma.
A coma is similar to a dream-like state because the individual is alive but not conscious. A coma occurs when there is little-to-no brain activity. The patient is unable to respond to touch, sound, and other stimuli. It is also rare for someone in a coma to cough, sneeze, or communicate in any way.
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].
A person in a coma is unconscious, not sleeping
Someone who is in a coma is unconscious and won't respond to voices, other sounds or any type of activity happening around them. A person in a coma is still alive, but the brain is functioning at its lowest stage of alertness.
In patients with a scale from 5 to 7, 53% will die or remain in a vegetative state, while 34% will have a moderate disability and/or good recovery. In patients with a Glasgow Coma Scale of 8 to 10, 27% will die or remain in a coma, while 68% will have a moderate disability and/or good recovery.
They said: 'The first few days was a genuine coma, after that it was induced by the doctors with ketamine. Waking up was kind of like emerging from deep waters. It took me a few days to actually be fully aware, I attribute that to the meds. 'Before that, it felt like time was skipping at random.
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.
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.
Elaine Esposito (December 3, 1934 – November 25, 1978) held the record for the longest period of time in a coma according to Guinness World Records, having lost consciousness in 1941 and eventually dying in that condition more than 37 years later.
What Happens During a Coma. A comatose person may move in ways that seem like they're awake, which can be misleading to friends and family. For example, they may grimace if something causes pain. However, these responses are just reflexes.
Someone in a coma needs intensive care in hospital. They may need help with breathing, they will be fed through a tube and they will receive blood and fluids through a drip inserted into the vein. The cause of their coma will also need to be treated to prevent further brain damage.
coma patients that are most aware of their environment react to pain as much as healthy people. Researchers who did the scans in Belgium say it justifies giving pain relief to all patients in this “minimally conscious state” (MCS).
Some people may recover from these states gradually, while others may not improve for years, if at all. 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.
If your family member is comatose, a mouth sponge, kind of like a little chunk of sponge on a stick, can be used to swab a bacteria killing solution called Peridex on the teeth a couple of times a day. Even a very small amount of this product will do quite a bit to reduce the effect of the comatose period on the teeth.
Comas can last from several days to, in particularly extreme cases, years. Some patients eventually gradually come out of the coma, some progress to a vegetative state or a minimally conscious state, and others die.
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.
On TV, it seems like someone in a coma wakes up right away, looks around, and is able to think and talk normally. But in real life, this rarely happens. When coming out of a coma, a person probably will be confused and only slowly respond to what's going on.
You can't "pull the plug" if there is brain activity. Longest coma someone woke up from was about 37 years. I would have to be sure that there was no chance for recovery.
Coma occurs when there is a serious problem with the brain's arousal system (the reticular activating system), or with its communications between other brain areas (such as the cerebral hemispheres) and the brain's activity becomes impaired.
In a coma, a patient is alive and there is some brain activity. Depending on the severity of the injury, recovery time varies and comas can be temporary or permanent. Patients in a coma might have brain stem responses, spontaneous breathing and/or non-purposeful motor responses.
The levels of response in the components of the Glasgow Coma Scale are 'scored' from 1, for no response, up to normal values of 4 (Eye-opening response) 5 ( Verbal response) and 6 (Motor response) The total Coma Score thus has values between three and 15, three being the worst and 15 being the highest.
