How do I know what stage my dad is at? He is 89.5 constantly repetitive,mostly incontinent and dosent /can't cook ...he dosent dress properly but sometimes manages to shave ! He can't remember yesterday and says his brain is muddled(on a good day) he won't have carers and got annoyed when I got the doctor out although he swears the doctor has never been out.He lives at home with his wife of 86 who has AML!!! I care for them both but don't know what stage he is classed as being at ...can anyone suggest??? Thank you
