Here the amount of recovery depends on the damage happening in brain and can not be predefined. Only once person comes out from Coma, after doing physical and medical evaluation we can assume how much recovery can be there in future. Yes but to prevent further bleeding and damage still the medication can be given to patient even though if he is in Coma,
Here, if the bleeding becomes too much then the surgical correction is also needed. That call will be taken by neuro surgeon.
Th fact is when the person is in Coma it is very difficult to judge what's happening inside brain. Until and unless we don't to testings in patients. And physical symptoms will be null so can not identify how much the functional ability is affected. So it is difficult to manage and improve but once the person comes out from Coma further guideline can be given. Take care
