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.
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.
Some people feel they can remember events that happened around them while they were in a coma, while others don't. Some people have reported feeling enormous reassurance from the presence of a loved one when coming out of a coma.
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.
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.
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.
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.
According to many coma survivors, the unconscious experience feels almost like a dream, at least in retrospect. One person said it was "kind of like a normal dream where you don't have any concept of time, but things seem to be happening." This person had "about four different dreams" in their less-than-a-week coma.
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.
A coma rarely lasts more than 2 to 4 weeks. Some patients may regain a degree of awareness after persistent vegetative state. Others may remain in that state for years or even decades. The most common cause of death for someone in a persistent vegetative state is infection, such as pneumonia.
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.
It can have a variety of causes, including traumatic head injury, stroke, brain tumor, or drug or alcohol intoxication. A coma may even be caused by an underlying illness, such as diabetes or an infection. Coma is a medical emergency. Quick action is needed to preserve life and brain function.
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.
Skin breakdown and ulcers occur commonly, since the person is unable to move and is incontinent, with no ability to control passage of urine or stool.
Rehabilitation centres and care homes. Most patients in a prolonged vegetative or minimally conscious state will eventually be transferred from hospital to a rehabilitation or long-term care setting.
The person's recovery depends on the cause and severity of the coma, but anyone who falls into a comatose state is at risk of dying. In some cases, there may be a complete recovery with no loss of brain functioning, while in other cases, lifelong brain damage is the result.
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.
Roving eye movements are slow, conjugate, lateral, and to-and-fro excursions, generally seen in normal sleep and in comatose patients with toxic, metabolic strokes 1.
Most comas do not last for more than two to four weeks, but there are patients who have woken after decades. The story of how Munira Abdulla spontaneously woke from a coma after 27 years has shed light on how someone could come back to life after decades of unconsciousness.
Some comas are caused by metabolic issues like diabetes. If doctors are able to administer medication to treat these problems, the coma can be broken. Comas created by brain tumors and severe brain injuries, however, may last longer since the underlying causes are usually harder to treat.
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.
CT scan. This uses a series of X-rays to create a detailed image of the brain. A CT scan can show bleeding in the brain, tumors, strokes and other conditions. This test is often used to diagnose and determine the cause of a 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.
