matters needing attention

Once the vegetative state continues for more than a few months, it is rare to get better. Adults in a persistent vegetative state have about 50% chance to regain a certain degree of consciousness within 6 months after head injury. They are able to respond to the environment and usually have permanent brain dysfunction. After half a year, fewer and fewer patients can have any systematic perception of the surrounding environment. Only 10% ~ 15% of the patients with vegetative state after cardiac arrest in hospital can recover consciousness, and no more than 5% of the patients with cardiac arrest outside the hospital can recover consciousness. About 60% of the children with persistent vegetative state after brain injury can recover consciousness within one year, but the prognosis of children with hypoxic brain damage is similar to that of adult cases, Only a small number of patients can recover consciousness to a certain extent after 6 months, so that they can take care of themselves independently.
