My dad had a stroke 1 yr. ago and about 2 wks. ago he had some paranoid and rages behavior. he got put in the hospital and meds got changed got home and was doing well. Then last week he felt like he was falling while lying still in bed and wasn't tracking and saying off the wall things. Back to the hospital. When he was admitted he was in acute renal failure. That has since cleared up and all blood work, ct scan, mri, and eeg have come back fine. My dad now is not with us at all and doesn't know who we are. Can you please give me some thoughts because all the doc. are scratching there heads because they don't know what to do next.
