She woke up and didn't recognize her room at all. Her vision seems to be greatly diminished. She's agitated and seems to be seeing things that aren't there. She is acting the same as when she was given morphine, ( irritable, obsessing with wrinkles in the blankets, hyper, suspicious) but we have asked repeatedly if she's been given anything different and have been told no. She has not been diagnosed with Alzheimers, but rather dementia (for whatever that's worth). It has been almost 3 weeks and there has been little change. A brain scan showed no change. MRI not given due to pace maker. We are completely stumped and are paying for 24 hour "eyes on" watch due to fall risk. She is able to get up and walk, though can't see well and will now wander. This over night drastic change has us all concerned and baffled.
