I urge you to be more realistic about the amount of skilled state of the art care given to patients in general, much less elderly residents of nursing homes.

Furthermore, from reading the alz.org caregivers forum, it appears that a number of people with dementia live in their homes and receive 24/7 care from their own families along with specialized care from doctors and therapists. And they still spend a great deal of time feeling frightened, lost, and lonely.
