In fact, even minimal improvement after this period is extremely improbable.

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. In the minimally conscious state, patients show preserved arousal level and exhibit discernible but fluctuating signs of awareness. Peripheral neuropathies can affect one or several sites in the body. Patients have fecal and urinary incontinence. Seizure activity may be present but not be clinically evident.Traditionally, a vegetative state that lasts > 1 month is considered to be a persistent vegetative state. Coma and Impaired Consciousness
Sufficient observation is needed. 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. Magnetic resonance angiography can be used to visualize the cerebral vasculature after exclusion of a cerebral hemorrhage.

1 In patients with traumatic head injury, a vegetative state that holds for more than 1 year is considered to be “permanent”, which implies irreversibility.
However, neuroimaging is indicated to rule out treatable disorders.The vegetative state must be distinguished from the minimally conscious state.

Pain usually elicits a motor response (typically decorticate or decerebrate posturing) but no purposeful avoidance.
The longer it has lasted, the less chance of patients recovering higher cortical function. Rarely, improvement occurs late; after 5 years, about 3% of patients recover the ability to communicate and comprehend, but even fewer can live independently; no patients regain normal function.If a vegetative state persists, most patients die within 6 months of the original brain damage. This state may be the first indication of brain damage or may follow a vegetative state as people recover some function. and, hence, of awareness whereas the vegetative state is defined by recovery of arousal in the absence of any sign of awareness. Diagnosis is based on clinical criteria. Hypothalamic and medullary brain stem functions remain intact to support cardiorespiratory and autonomic functions and are sufficient for survival if medical and nursing care is adequate.

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.
Basal Ganglia: Regional Dissection
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. The cause is usually pulmonary infection, urinary tract infection, or multiple organ failure, or death may be sudden and of unknown cause. 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)Providing physical therapy to prevent limb contracturesVegetative state has no specific treatment. In both cases, the patient is alive, but the brain does not function fully.
