My husband is fighting Alz's; one moment he knows who I am, then doesn't know me in the next. I am sure he 'sees' things I don't see also. The only time he seems disturbed is when he sundowns and thinks people are out to kill him (career Navy). I assure him, calmly the staff is here to protect us.
I try to focus on "glass half full". My husband may not know who I am but each time he does choose me!! He is so thankful when I tell him I love him and I am married to him!! We can be happy together in that moment. In everyday life we do actually choose to be married to our loved one
Eventually as AD progresses, the whole body may be impacted. Vision may change. Your person may loose ability to speak, hold silverware, forget how to swallow, hands may curl up, forget how to walk. There's no time table to guide if/when these things may happen.
I try to keep my focus on what we can do today. I may have an idea or two for tomorrow. I have a big overarching view of the future but not long range specific plans because that takes too much effort and emotion especially if something doesn't pan out!! My plate is so full I have to be careful not to overextend myself so I have energy to enjoy and appreciate today.
Love, hugs & prayers for all on this bizarre journey!! Keep your nose above water!!
