A vegetative person is in a persistent vegetative state, which is in fact a special kind of consciousness disorder with consciousness but no cognitive ability, and is related to abnormalities of the nervous system, metabolic diseases, acute brain injuries and other factors. Although the vegetative person in this state can’t move his body, can’t make normal response to external stimuli, and doesn’t have the ability to take care of himself at all, his consciousness exists. The vegetative person can hear other people’s words and feel other people’s touch. After positive and persistent treatment or continuous external stimulation, the vegetative person can make some weak responses, such as frowning, finger flexion, tears, etc., and even have the possibility of resuscitation. Therefore, family members should have a positive attitude, pay attention to verbal expression when communicating with the vegetative person, and give appropriate stimulation to help him/her regain consciousness as soon as possible.
