Last Summer my wife asked me who I was a few times - even waking me in the middle of the night to ask me on two occasions. On other occasions she has asked me if I’m David or called me mummy or daddy. Most of these occasions coincide with short periods of increased confusion and they don’t last. It’s as if her brain is going through a computer like reboot so not working properly for a while. I don’t let it ruffle me and always assume that it’s just another little bit of brain being lost and the signals being rerouted.
