My Mum too, although she doesn't have Vascular Dementia (so far as we know!).jenniferpa said:... she becomes fixated on something .... this went on then suddenly, that was replaced by something else to worry about. Jennifer
She'll drive me to distraction by obsessing about one thing for weeks, then it will suddenly disappear off the radar completely, to be replaced in her mind by something else. I TRY (not always successfully) to tell myself it's real to her at the time. Not being a saint, I usually end up snapping at her sometime during the fixation stage.
