ABSTRACT
The study of consciousness disorders is a scientifi c challenge,
and clinical differentiation among the various sorts of alterations
in consciousness is diffi cult. Persistent vegetative state was defi
ned in 1972, but years later cases appeared in which diagnosed
patients showed signs of cognitive activity, and therefore could
not be considered vegetative. Minimally conscious state was defi
ned in 2002. This article discusses minimally conscious state
based on a literature review and the author’s clinical experience.
A brief historical outline is given, starting from 1886 when Horsley
analyzed level of consciousness. The article reviews criteria
for defi ning minimally conscious state, as well as the differential
diagnosis from persistent vegetative state, brain death, coma,
locked-in syndrome and akinetic mutism. Modern discoveries
of residual cognitive functioning and new neural correlates have
contributed to increased knowledge of this condition. Regardless,
minimally conscious state continues to be a challenge for neuroscientists
around the world, with issues still to be resolved.
