Hi doctor, My father is 55 years old. He is good in terms of his health and weight. He recently had a large AVM rupture and he was flown to the nearest hospital. He had a craniotomy to remove AVM and the ICH caused a large stroke. He was left paralyzed on his right side with the capability to speak, but limited. He says a few words here and there, but mostly mumbles or says things that do not fit the context of the present. He is in a rehabilitation where they are supposed to be helping him with this now. My concern is that recently he keeps having the episodes of losing consciousness. For a few times it happened for about 10 minutes and today for over an hour. He was calm and sitting up. He laid back down slowly (with my help, of course) and all of a sudden would not wake up. His vitals were fine though they had put him on oxygen this afternoon, because it was a little low (high 70's and low 80's). He was on it when this occurred. Is there any indication as to why this is happening? He has been sent to the emergency room for it a bunch of times, but each time they send him back after doing a CAT scan. By the time he would see the doctor, he would be awake. Recently, his medication was changed from Keppra to Lamictal. He has been experiencing a bit of tremors as well and I am not sure if it is the new medicine. They will be scheduling him for a neurologist appointment and an MRI in the upcoming week. Do you have an idea as to why these unconsciousness occurs? He communicates sometimes by saying yes or no, but it is inconsistent. He goes in little stages of being combative, calm, sleeping, aggressive and then basically aware. Could this unconsciousness be one of these? I seem to be the only one extremely concerned about them, but he has not seen a neurologist about it. Please help me.
