I wonder if there are special medical facilities at his home in Delaware for treating his dementia to keep it more secret. If so it ain’t working to improve his status.

It’s his home. Dementia patients are vastly more comfortable in their homes (surroundings they know) than unknown surrounding (think White House). There is less confusion at home.
Evidence: that incident where he had trouble finding the door to the White House with two aides guiding him in.
