Persistent vegetative state; Unresponsiveness wakefulness syndrome
Apallic syndrome is an older term that was first replaced by persistent vegetative state. More recently, unresponsive wakefulness syndrome (UWS) is the proposed nomenclature. The syndrome is a clinical condition describing patients who fail to show voluntary motor responsiveness in the presence of eyes-open wakefulness. Patients show reflexive behavior such as spontaneous breathing, but no signs of awareness of the self or the environment. A thorough clinical evaluation may be required to distinguish between UWS and other conditions, including coma, brain death, and locked-in syndrome.
