92 yo discharged from 2-day hospital obs at 5pm. disoriented to place. now confusing people and events. pleasant but juvenile. delerium or sundowning?

Both: Can be both. Delerium is a reversible, acute change in mental status. Sundowning occurs when folks with dementia or delirium get tired towards the later part of day and have a change in mentation. In this case it could be both. Treat underlying cause of delirium and give it time. If they are in danger of hurting themselves, get medical help.

Or both: The information provided supports either diagnosis and the treatments overlap greatly. I think the important point is that both issues are treatable and should be addressed.

These are signs of dementia, and statistically, higher likelihood of Alzheimer's, but other problems such as vascular dementia may be considered. A neurologist can evaluate and provide medications which may benefit.
