My husband asked me to post this for comments. His Mom is 88 and quite active. Has mild/moderate Alzheimer's. Insists on living along. Forgets that due to osteoporosis she is not supposed to climb on ladders, pick up large and heavy objects etc. Keeps hurting herself and breaking more vertabrae. Her doctor is of the opinion to let nature take its course since she fights tooth and nail with anyone (doctor, lawyer, her only son) who might suggest anything. Always a no.
And since you are not supposed to try to reason with a person with dementia, what do you do?
Her viewpoint is "leave me alone. I am not hurting anyone."
