Age 23. coma patient. diffused axonal injury. intraventricular hemmorhage. bleeding in frontal lobe. chances of survival? any possible impairment?

Not good : Sorry about this one, but there will be a suboptimal outcome at best. Survival may be issue, talk to your doctors, and perhaps an eeg can guide decisions, but hard to predict outcome of comas. Sounds like a profound traumatic event, and since young and severe, have a family conference with the treatment team, and get all your questions answered.
