rede--My very old mother (96) was doing well until about a year ago. One thing I have noticed recently is that what I think you mean by "subjective aspect of experience" has completely disappeared for her. It is as though someone has pressed the delete button and the whole experinence has vanished. It is most distressing to watch but she seems unaware of it unless her attention is drawn to it when she gets cross and argues it never hasppened. This is not the same as forgetting, it just wasn't there to remember. The odd part of it is that she enjoys life in the present, there seems to be participation and enjoyment---just NO recall whatsoever.
