I know you will find many friends and help on this board. There is a wealth of information and you will find answers to many of your questions as I have!
My husband just turned 75 in December and was diagnosed with AD five years ago. He too is in the mood swing stages and becomes very angry and swears and talks to himself a lot. If I take issue with anything he says he gets right in my face and yells at the top of his lungs. Sometimes it scares me a little and my kids are worried about me. However, he has never laid a hand on me (yet).
I don't know if you have noticed whether or not this is more common in the everning than during the morning hours. I notice that this is most common with my husband in the late afternoon or evening hours. Nothing is right with him then and he finds fault with the food I prepare and says it tastes like cement and spits it out, etc. He doesn't seem to like the foods that he used to really enjoy. I have noticed also that he seems to go for the soft food. Has anyone else found this to be true???
This stage has been lasting a while and I sure will be glad when it passes. I don't mean for him to become worse faster but this is really miserable!!!!
Take care and good luck to you.
