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.
Most comas don't last more than two to four weeks. Recovery is typically gradual, with patients gaining awareness over time. They may be awake and alert for just a few minutes the first day, but gradually stay awake for longer and longer periods.
Can Your Loved One Hear You? During a coma, the individual is unconscious, meaning they are unable to respond to any sounds. However, the brain may still be able to pick up on sounds from loved ones. In fact, some studies suggest talking and touching a loved one while they are in a coma may help them recover.
Post-traumatic amnesia typically occurs after a survivor wakes up from a coma, a period of unconsciousness. During this time the survivor may not be able to recall certain memories. This can last from a few minutes to a couple weeks, depending on the severity of the brain injury.
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.
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.
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.
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 .
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. They may need physiotherapy, occupational therapy and psychological assessment and support during a period of rehabilitation, and may need care for the rest of their lives.
The patient will be confused about where he or she is and what has happened. The patient will have difficulty with memory and behavior. The patient's confusion may lead to yelling, swearing, biting, or striking out.
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. However, stress is low.
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.
Depth of coma
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.
Coma is a state of unconsciousness in which a patient does not react with the surrounding environment. 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.
Comas are usually side effects of: Blunt trauma: When the brain swells, causing certain parts of the RAS (reticular activating system) to shut down, this can cause a person to enter a comatose state.
Brain death: Irreversible cessation of all functions of the entire brain, including the brain stem. A person who is brain dead is dead, with no chance of revival. Coma: A state of profound unresponsiveness as a result of severe illness or brain injury.
Coma is caused by dysfunction of the reticular activating system (RAS) in the brain stem or both cerebral hemispheres.
People in a coma are completely unresponsive. They do not move, do not react to light or sound and cannot feel pain. Their eyes are closed.
Drug induced comas are used to protect the brain during major neurosurgery, as a last line of treatment in certain cases of status epilepticus that have not responded to other treatments, and in refractory intracranial hypertension following traumatic brain injury.
Familiar Voices And Stories Speed Coma Recovery
Patients in comas may benefit from the familiar voices of loved ones, which may help awaken the unconscious brain and speed recovery, according to research from Northwestern Medicine and Hines VA Hospital.
When someone is in a coma, they cannot interact with their environment. The brain is still working, however, and the degree of brain activity varies from patient to patient. New tools for mapping brain activity have helped doctors illuminate what is happening inside the brain, which informs their treatment and care.
A coma patient's lack of a gag reflex and use of a feeding tube can result in food, drink or other solid organic matter being lodged within their lower respiratory tract (from the trachea to the lungs).
In some cases, it may be that the family believe that the patient would have wanted ongoing treatment regardless of their level of consciousness or prognosis. Alternatively, some family members may be hoping for a “miracle” recovery or are simply not yet ready to let go of a loved one.
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.
