Example text

The patients described by French had been observed in the period 19461951 and the similarity of their clinical features to those described as PVS two decades later suggests that vegetative states did not suddenly emerge from nowhere as a new condition due to the introduction of intensive care, but had occurred previously as unaggregated, and variously categorised, cases. The increasing incidence of PVS has been identified frequently as a looming issue in resource allocation.

A change from discussing permanence of PVS to specifically designating an additional condition as the permanent vegetative state became apparent in 1995 in the practice parameters of the American Academy of Neurology (Quality Standards Committee 1995). The permanent vegetative state was defined by its irreversibility, so conflating permanence and irreversibility. An irreversible condition will always be permanent: a condition which will be permanent, in the absence of successful intervention, need not be irreversible (Howsepian 1996).

This risk will be especially high if one is examining the brain, an organ unique in the multiplicity of different structures and the complexity of their connections. In searching at autopsy for abnormal structural correlates specific for loss of capacity for consciousness in the absence of some working hypothesis that directs attention to localised regions of brain tissue, it is probable that an enormous data collection over a prolonged period would be necessary even to examine a small group of patients.
