When someone is in a prolonged state of unconsciousness, they are in a coma. This is a medical emergency, and immediate action is required to save the individual’s brain function and life.
A series of blood tests and brain scans will be conducted to determine the cause of the coma so that the correct treatment can be administered as soon as possible.
It is rare for a coma to last longer than several weeks. When people are unconscious for an extended period of time, they are classified as being in a persistent vegetative state or brain death.
A coma is caused when there is a serious problem with the brain’s arousal system or the reticular activating system or with its communications between other brain areas, such as the cerebral hemispheres. These problems cause the brain’s activity to become impaired.
There are many possible causes for someone to experience a coma. According to the National Institute of Neurological Disorders and Stroke, some of the most common causes include:
Symptoms of a coma typically include the following:
Many people slowly recover from a coma, while others succumb to a persistent vegetative state or death. According to the Mayo Clinic, survivors of comas may be left with a mild or severe disability, typically due to the cause of the coma or delayed treatment.
Other problems people in comas commonly experience are:
Doctors will search for the cause of the coma, but a proper diagnosis may take hours or even days because of all the diagnostic testing that needs to be performed. Coma is a medical emergency, so the patient will be given immediate intensive care, which may include any or all of the following:
The severity and cause of the coma will determine the proper course of treatment. The most common treatments include:
Comas are very serious. Anyone who becomes comatose has a high chance of not waking up again.
Death is a strong possibility. Recovery mostly depends on the severity and the cause of the coma, as well as the treatment and how quickly the patient received that treatment.
There are many cases where the patient makes a full recovery with no lasting side effects. Unfortunately, there are also a large number of people who suffer various amounts of brain damage and lost brain function.
The symptoms from the damage may last for the survivor’s lifetime.
When people do not recover from a coma, they may descend into a persistent vegetative state. This is where the brain loses all higher functioning, such as consciousness, personality, and self-awareness.
The brain is still capable of maintaining involuntary functions, such as heart rate, breathing, blood pressure, and swallowing.
A vegetative state typically occurs when someone has suffered from a severe traumatic brain injury or when they have been deprived of oxygen for a prolonged amount of time. Doctors typically wait until the coma has lasted for at least three weeks before diagnosing a persistent vegetative state.
The patient may still respond to loud noises, breathe, and swallow, but they will not be capable of achieving consciousness or displaying personality.
A vegetative state may continue for months or even years with the proper care. The longer someone remains in this form of coma, the less likely they are to make a recovery.
Vegetative state coma patients are similar to coma patients. Some of the characteristics of this prolonged state include:
Common complications patients may suffer from while in a persistent vegetative state include:
If there is any hope that the patient will recover from their comatose condition, it is critical that they are kept as healthy as possible. There is no way to know how long a vegetative state will persist, but the patient’s chances of recovery decrease the longer they remain in a coma.
When the patient’s family wishes to continue medical care for the patient in hopes that they will recover, the ongoing treatment will include:
Recovery from a vegetative state is possible, but it is typically a slow process. The patient will first become aware of their surroundings and eventually become able to respond.
Sadly, only a very small number of people who wake up from a persistent vegetative state that has lasted over six months are able to continue with their daily activities and live independently. The vast majority of these survivors remain permanently disabled with brain damage.
When someone has suffered from severe brain damage and is no longer able to breathe on their own, they are diagnosed with brain death. Patients with brain death need to be kept on a respirator to keep their bodies alive.
Patients are given an electroencephalogram or EEG to check for brain activity. When there is no brain activity, that person has suffered brain death and is considered to have died.
Their heart will continue to beat, but the person will die when disconnected from the medical machinery.
The damages suffered by someone who had sustained a coma are often monumental. Patients and their families have to deal with ongoing medical and nursing home care, lost wages, loss of future income, and loss of enjoyment of life.
