My Mother, who is 92 on Friday has, in the last year, being going downhill, mentally, with vascular dementia. For her age, she was remarkable active, going shopping, walking far more, and further than people 15 years younger. She has been living with me for the last 3 years but the rate of mental deteriation is very difficult to cope with.
She is currently in a 'stepdown' accommodation, halfway between hospital and a nursing home/home. The Consultant in Elderly Care does not think she will ever be able to return home, something which is very hard to accept. Dementia is like a living death, the person you have known is no longer there in mind, just the body.
