Wife of 50 years has Alzheimer's. She is 71 y/o. She still recognizes me and our son. She does go to daycare at a memory care center and seems happiest when at the center. Her daycare center is where she is most likely to be placed. Geriatric psychiatrist defines condition as severe.
But please, make sure that you have support for yourself at this time. Make sure that you are eating properly and will be getting enough sleep. Do you have outside interests to keep you involved and busy? Once she has moved, there will be a big change in your household, please be on the lookout for changes in yourself that might need attention. God bless you for taking such good care of your wife. Good wishes to both of you as you work through this.
