Things were probably first really noticeable when one evening, we were at a concert and I had become acutely confused. Sue became worried when I had not returned after a comfort break. She had to send an attendant to look for me. When he located me, he clearly thought I was intoxicated and we made a hasty retreat back home. Shortly afterwards on a weekend break to London the same thing happened when, on the third morning, I could not locate the breakfast buffet (even though I had used it the previous two mornings). Then as we disembarked from the plane home later that day, I told my wife that she was in no fit state to drive as she had had too much to drink.... It was 10 am. At this point, Sue finally persuaded me to seek advice from my neurological colleagues (she had been at me for weeks to do so) and one of my colleagues, who was on call that weekend, kindly came out to see me at home that day. He immediately realised that there was indeed something wrong and arranged an urgent MRI. I had this the next day (probably a case of not what you know but who you know). As Sue was driving me home, we got the phone call that no one really wants:
