An 86-year-old is brought in by her daughter due to a week

history of confusion and inability to manage at home.  She has been living independently for the

last 12 months since being widowed, but in the last week there have been times where she has not remembered to take her medications or eat meals at the right time.  She was seen by the GP but at that point seemed reasonably good and the GP didn't think there was anything to worry about. Her daughter has no confidence in the GP

and hence brought her into the ED.

Which of the following in the history is suggestive of

delirium and not dementia?
