1, voluntary movement's loss, limbs sometimes have flexion escape response to pain stimuli. Therefore, such patients can't move or change their body position by themselves, but lie in bed and must be taken care of by others.

3. Loss of active eating ability, confusion between hunger and satiety, and sometimes swallowing, chewing and grinding teeth.

4, incontinence.

5. EEG is flat or has resting potential, and high amplitude slow wave or occasional α rhythm may appear several months after injury.

Restoration of plant state:

Once the vegetative state lasts for more than a few months, it rarely improves, and no one can fully recover. Adults who are in a persistent vegetative state have a 50% chance of recovering consciousness and responding to the environment within 6 months after head injury.

Permanent brain dysfunction usually occurs. After half a year, fewer and fewer patients can have any systematic perception of the surrounding environment.

Only 65,438+00% ~ 65,438+05% of patients in vegetative state after cardiac arrest in hospital can regain consciousness, and less than 5% of patients in vegetative state after brain injury can regain consciousness.

About 60% can regain consciousness within 1 year, but the prognosis of children with hypoxic brain injury is almost the same as that of adults. Only a few cases can recover a considerable degree of consciousness after 6 months, so that they can live independently.
