Hi - I am in a very similar situation to you. My husband - 73 - has been having memory and delirium problems. We are actually going for the scan today - Bath. Once the doctor said he need a scan and booked it he has just gone along with the idea. It has taken quite sometime for the appointment to come through, I would suggest that you get the appointment booked and don't worry until you've got a date. Then tell him its a regular check up that they do now - for men/women of a certain age. xxx
