<P> A persistent vegetative state ( PVS ) is a disorder of consciousness in which patients with severe brain damage are in a state of partial arousal rather than true awareness . After four weeks in a vegetative state ( VS ) , the patient is classified as in a persistent vegetative state . This diagnosis is classified as a permanent vegetative state some months ( 3 in the US and 6 in the UK ) after a non-traumatic brain injury or one year after a traumatic injury . Nowadays , more doctors and neuroscientists prefer to call the state of consciousness an unresponsive wakefulness syndrome , primarily because of ethical questions about whether a patient can be called `` vegetative '' or not . </P>
