<P> Coma has a wide variety of emotional reactions from the family members of the affected patients, as well as the primary care givers taking care of the patients . Common reactions, such as desperation, anger, frustration, and denial are possible . The focus of the patient care should be on creating an amicable relationship with the family members or dependents of a comatose patient as well as creating a rapport with the medical staff . </P> <P> Comas can last from several days to several weeks . In more severe cases a coma may last for over five weeks, while some have lasted as long as several years . After this time, some patients gradually come out of the coma, some progress to a vegetative state, and others die . Some patients who have entered a vegetative state go on to regain a degree of awareness . Others remain in a vegetative state for years or even decades (the longest recorded period being 42 years). </P> <P> The outcome for coma and vegetative state depends on the cause, location, severity and extent of neurological damage . A deeper coma alone does not necessarily mean a slimmer chance of recovery, because some people in deep coma recover well while others in a so - called milder coma sometimes fail to improve . </P> <P> People may emerge from a coma with a combination of physical, intellectual, and psychological difficulties that need special attention . Recovery usually occurs gradually--patients acquire more and more ability to respond . Some patients never progress beyond very basic responses, but many recover full awareness . Regaining consciousness is not instant: in the first days, patients are only awake for a few minutes, and duration of time awake gradually increases . This is unlike the situation in many movies where people who awake from comas are instantly able to continue their normal lives . In reality, the coma patient awakes sometimes in a profound state of confusion, not knowing how they got there and sometimes suffering from dysarthria, the inability to articulate any speech, and with many other disabilities . </P>
