Chronic wakefulness symptoms have Immunity building supplements and urinary incontinence. Cranial nerve and spinal reflexes are typically preserved.
Rarely, brain activity, detected by functional MRI or electroencephalography EEGindicates a response to questions and commands even though there is no behavioral response covert consciousness.
The extent of patients' actual awareness is not yet known. In most patients who have such brain activity, the vegetative state resulted from traumatic brain injury, not hypoxic encephalopathy.
Fragments of meaningful interaction with the environment are preserved. Patients in a minimally conscious state may do the following:. A vegetative state is suggested by characteristic findings eg, no purposeful activity or comprehension plus signs of an intact reticular formation.
Diagnosis is based on clinical criteria. However, neuroimaging is indicated to rule out treatable disorders. The vegetative state must be distinguished from the minimally conscious state. Both states can be permanent or temporary, and the physical examination may not reliably distinguish one from the other.
Sufficient observation is needed. If observation is too brief, evidence of awareness may be overlooked. Some patients with severe Parkinson disease are misdiagnosed as being in a vegetative state. CT or MRI can differentiate an ischemic infarct, an intracerebral hemorrhage, and a mass lesion involving the cortex or the brain stem.
Magnetic resonance angiography can be used to visualize the cerebral vasculature after exclusion of a cerebral hemorrhage. Diffusion-weighted MRI is becoming the preferred imaging modality for following ongoing ischemic changes in the brain.
Positron emission tomography PETfunctional MRI, and single-photon emission computed tomography SPECT can be used to assess cerebral function rather than brain anatomy. If the diagnosis of persistent vegetative state is in doubt, PET, SPECT, or functional MRI should be done.
In some cases, these tests can show whether parts of the brain, such as the cortex, are still functioning even if it is not evident during clinical examination.
Prognosis varies somewhat by cause and duration of the vegetative state. Prognosis may be better if the cause is a reversible metabolic condition eg, toxic encephalopathy than if the cause is neuronal death due to extensive hypoxia and ischemia or another condition.
Also, younger patients may recover more motor function than older patients but not more cognition, behavior, or speech. Recovery from a vegetative state is unlikely after 1 month if brain damage is nontraumatic and after 12 months if brain damage is traumatic.
Even if some recovery occurs after these intervals, most patients are severely disabled. If a vegetative state persists, most patients die within 6 months of the original brain damage.
The cause is usually pulmonary infection, urinary tract infection, or multiple organ failure, or death may be sudden and of unknown cause. A few patients live for decades. Most patients tend to recover consciousness but to a limited extent depending on how long the minimally conscious state has lasted.
The longer it has lasted, the less chance of patients recovering higher cortical function. Prognosis may be better if the cause is traumatic brain injury.
Rarely, patients regain clear but limited awareness after years of coma, called awakenings by the news media. Supportive care is the mainstay of treatment for patients in a vegetative state or minimally conscious state; it should include the following:.
Preventing systemic complications due to immobilization eg, pneumonia, urinary tract infection, thromboembolic disease. Preventing pressure ulcers Prevention Pressure injuries are areas of necrosis and often ulceration also called pressure ulcers where soft tissues are compressed between bony prominences and external hard surfaces.
They are caused Vegetative state has no specific treatment. Decisions about life-sustaining care should involve social services, the hospital ethics committee, and family members. Maintaining patients, especially those without advanced directives Advance Directives Advance directives are legal documents that extend a person's control over health care decisions in the event that the person becomes incapacitated.
They are called advance directives because read more to guide decisions about terminating treatment, in a prolonged vegetative state raises ethical and other eg, resource utilization questions.
Most patients in a minimally conscious state do not respond to specific treatments. However, in some cases, treatment with zolpidemapomorphineor amantadine can lead to improvement in neurologic responsiveness for as long as the drug is continued.
A growing number of studies are evaluating the effects of providing music interventions during disorders of consciousness 1 Treatment reference A vegetative state is absence of responsiveness and awareness due to overwhelming dysfunction of the cerebral hemispheres, with sufficient sparing of the diencephalon and brain stem to preserve Some studies show that music therapy may lead to positive behavioral effects and return to normal physiologic responses.
Results should be interpreted with caution because research in this area has thus far been limited. Li X, Li C, Hu N, Wang T : Music interventions for disorders of consciousness: A systematic review and meta-analysis.
J Neurosci Nurs 52 4 : —, doi: Vegetative state is typically characterized by absence of responsiveness and awareness due to overwhelming dysfunction of the cerebral hemispheres, intact brain stem function, and sometimes the simulation of awareness despite its absence. Minimally conscious state differs from vegetative state in that patients have some interaction with the environment and tend to improve over time.
Diagnosis requires exclusion of other disorders and often prolonged observation, particularly to differentiate vegetative state, minimally conscious state, and Parkinson disease. Learn more about the Merck Manuals and our commitment to Global Medical Knowledge.

Another group of brain disorders, called spongiform encephalopathies, are caused by read more can result in a vegetative state. People in a vegetative state can do some things because some parts of the brain are functioning:. They have relatively regular sleeping and waking patterns but not necessarily related to day and night. Because of these responses, they may appear to be aware of their surroundings. However, they have no awareness of themselves or their environment. Their apparent responses to their surroundings result from automatic involuntary basic reflexes and not from a conscious action. For example, they may instinctively grasp an object when it touches their hand, as a baby does. People in a vegetative state cannot do things that require thought or conscious intention. They cannot speak, follow commands, move their limbs purposefully, or move to avoid a painful stimulus. Most people in a vegetative state have lost all capacity for awareness, thought, and conscious behavior. However in a few people, functional magnetic resonance imaging Functional MRI Magnetic resonance imaging MRI is a type of medical imaging that uses a strong magnetic field and very high frequency radio waves to produce highly detailed images. During an MRI, a computer read more fMRI and electroencephalography Electroencephalography Diagnostic procedures may be needed to confirm a diagnosis suggested by the medical history and neurologic examination. Imaging tests commonly used to diagnose nervous system neurologic disorders read more EEG have detected evidence of some brain activity suggesting possible awareness. In these people, the cause was usually a head injury, not a disorder that resulted in the brain being deprived of oxygen. When the people were asked to imagine moving a part of their body, these tests showed appropriate brain activity for such an action although the people did not do the action. However, these tests cannot determine how much awareness these people have. Awareness that can be detected only by these tests is called covert hidden consciousness. People in a vegetative state have no control over urination and bowel movements are incontinent. People in a vegetative state go to sleep and awaken regularly, and their eyes open and move, but typically, they have lost all capacity for thought and conscious behavior. Doctors suspect a vegetative state based on symptoms. However, before a vegetative state can be diagnosed, people should be observed for a period of time and on more than one occasion. If people are not observed long enough, evidence of awareness may be missed. People who have some awareness may be in a minimally conscious state Minimally Conscious State A minimally conscious state is severe but not complete impairment of awareness. read more rather than a vegetative state.

Some people spontaneously recover from a vegetative state, but recovery is usually incomplete. The chances of recovery depend on the cause and extent of the brain damage and the person's age, as for the following:. Some recovery is more likely if the cause is a head injury, a reversible metabolic abnormality such as low blood sugar , or a drug overdose rather than a major stroke or cardiac arrest. Younger people may recover more use of their muscles than older people, but differences in recovery of mental function, behavior, and speech are not significant. If a vegetative state lasts for more than a few months, people are unlikely to recover consciousness. |

Some recovery is more likely if the cause is a head injury, a reversible metabolic abnormality such as low blood sugar , or a drug overdose rather than a major stroke or cardiac arrest. Younger people may recover more use of their muscles than older people, but differences in recovery of mental function, behavior, and speech are not significant. If a vegetative state lasts for more than a few months, people are unlikely to recover consciousness. If people do recover, they are likely to be severely disabled. Any recovery from a vegetative state is unlikely after 1 month if the cause was anything other than a head injury. If the cause was a head injury, recovery is unlikely after 12 months. However, a few people improve over a period of months or years. Rarely, improvement occurs late. Most people who remain in a vegetative state die within 6 months of the original brain damage. Most of the others live about 2 to 5 years. The cause of death is often a respiratory or urinary tract infection or severe malfunction failure of several organs. But death may occur suddenly, and the cause may be unknown. A few people live for several years. There have been reports of people regaining some awareness after spending years in what appears to be in a vegetative state or coma. These reports often involve people who had been in a minimally conscious state, usually after a head injury. Chances of recovery from a minimally conscious state are unpredictable but better than those from a vegetative state. Music therapy may have slight beneficial effects by stimulating a response in people in a vegetative state or other types of impaired consciousness. But the usefulness of this therapy is as yet unclear. Like people in a coma Stupor and Coma Stupor is unresponsiveness from which a person can be aroused only by vigorous, physical stimulation.

Contractures: Lack of movement can also lead to permanent stiffening and shortening of muscles contractures causing joints to become permanently bent. Blood clots: Lack of movement makes blood clots more likely to form in leg veins—called deep vein thrombosis Deep Vein Thrombosis DVT Deep vein thrombosis is the formation of blood clots thrombi in the deep veins, usually in the legs. Blood clots may form in veins if the vein is injured, a disorder causes the blood to clot Pressure sores can be prevented by frequently repositioning the person and placing protective padding under parts of the body that are in contact with the bed, such as the heels, to protect them. Preventing blood clots includes use of drugs Anticoagulant medications Deep vein thrombosis is the formation of blood clots thrombi in the deep veins, usually in the legs. read more and compression or elevation of the person's legs. Moving the limbs, as occurs in passive-range-of-motion exercises, may also help prevent blood clots. Because people are incontinent, care should be taken to keep the skin clean and dry. If the bladder is not functioning and urine is being retained, a tube catheter may be placed in the bladder to drain urine. Catheters are carefully cleaned and regularly examined to prevent urinary tract infections from developing. If recovery is unlikely, doctors, family members, and sometimes the hospital ethics committee should discuss how aggressively future medical problems should be pursued and when and if life-sustaining treatment should be withdrawn.

The mother remained in an unaware and unresponsive state for another month before she died. In another case , a woman was about 4 weeks pregnant when she entered an unaware and unresponsive state. With care, she was able to carry the fetus for another 29 weeks. Following premature labor, she gave birth to a healthy baby. The mother remained in the same neurological state. A person in this neurological state can survive for decades, but most people will only survive for a few years. As a family member, you may have to make many important decisions about their care, such as:. If the person has no living will or medical power of attorney, it may be helpful to consult with an attorney about your rights and responsibilities. Some will gradually regain consciousness.

Among people with TBI who remain in an unaware and unresponsive neurological state for a month, about 50 percent regain consciousness. Some may be left with chronic disabilities. Recovery may be more difficult for people who experienced illness or nontraumatic brain injury. Those who do regain consciousness after an extended period may be left with severe disabilities due to brain damage. They might be in a minimally conscious state at first, so progress can stall and gradually improve again. Recovery varies from person to person. After thorough evaluation, the doctor can provide more information about their general outlook and what you can do to help. Your brain stem still functions, and you move through a sleep-wake cycle.
