<s>[INST] HI My grandmother has been unconscious in a hospital for more than a week now. She had very low sodium and Calcium. She has been receiving IV fluid and oxygen in ICU and now her sodium as well as calcium is normal but, she hasn t gained consciousness yet. Doctors have done all kinds of tests but they didn t find anything abnormal. She seems to be in pain. She clutches and shakes her right hand every time she feels pain. No response from the left portion of her body. She also opens her eyes and blinks fast several times a day. She had abdomenal pain before she got unconscious. No diagnosis has been made so far. [/INST] Dear friend. Do you have a CT scan or MRI report done on your grandmother's brain. Low sodium & calcium can cause problems but does not usually cause a deep level of unconsciousness. Of course it is good that gradually it has been corrected.One of the reasons for unconsciousness at this age is a stroke .This happens either due to a blood clot blocking the blood vessels of the brain so that part of the brain dies which results in a lack of functioning in those parts of the body that are supplied by that part of the brain. A stroke can also occur when the blood vessels in the brain burst either due to a bulge in the vessels or due to raised blood pressure etc. I may be able to give a better explanation if I get more information on the medical problems that your grandmother had earlier, the medications and the tests & investigations reports. Best regards. </s>
