I can have sensible logical conversations with my wife, sometimes. Other times she will talk completely randomly about nonsense. Her mood can also change rapidly from being loving to being stand-off-ish and downright horrid. She will seem to be fully aware of where we are and who I am and then quickly demand to go home and need to ring "me" because I will be worried about her (even though I am with her). In summary, I never seem to know where I stand anymore and just when I think (almost forgetting the dementia) that we are having a "normal" conversation, like we have done for the last 30 years, she will do something that snaps me back to the present and I feel helpless again. We are 2 years 6 months following diagnosis and her random mood changes seem to have increased, as have other behavioural traits like moving and hiding things. Is this usual progression? I wish I knew which "version" of my wife I was dealing with ! Any thoughts or advice please? Thank you
