The probability of awakening from a brain hemorrhage vegetative, if we look at the global statistics, will be about 10-15%, but it must be treated specifically according to the specific condition of each person. In general, if it becomes a vegetative state, it means that the condition is very serious. And an EEG must be done to clarify whether there are stimulated brain waves generated or whether there is a normal cranial waveform. Often vegetative people do not have such waveforms, signaling that they will not be able to wake up in the later stages, and many people will exist in a state of brain death. However, in the vegetative state of survival, wakefulness promotion is a hope and a means, the main one is neuroelectrical stimulation therapy, but it is not particularly reliable and not as life-saving as craniotomy for brain hemorrhage, which is relatively expensive and has a low success rate, but it is still in a research state.
