puppydog, this is your second post in 11 days. I responded to your Aug 17th post asking you for more information but you did not respond.
I don't want to appear rude, but this site is for spouse caregivers. Are you a spouse caring for your spouse with dementia? What do you mean by 3rd stage? What type of help/advice do you need? We need to know more so we can help you.
Perhaps if you do not want to provide more information this is not the appropriate forum for you.
