<s>[INST] my dad went into a coma following a heart attack after two weeks we were told he was in a vegetative state he is recieving no support apart from being fed and is completely supporting himself, yesterday he woke up and tried to talk several times he also responds to some commands does this mean he may recover ? [/INST] Hello, The situation you have mentioned is very positive as long his recovery is concerned. He is most probably in the recovery phase.  It all depends on the severity and Reversibility of brain trauma or the cause of unconsciousness. Just keep on feeding him.  Keep his pelvic area washed or moped at least once a day. Keep on giving him passive exercises and keep on changing his posture 2 hourly so that he doesn't develop bedsores.  This will help your patient to be in a better physical state once he is out of the coma. And I am good sure about his recovery.  The extent of recovery will be dependent on the severity of brain trauma, which in most cases is irreversible, if there. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  </s>
