Peter's diagnosis was made on the basis of a MRI brain scan he had. It showed significant areas of atrophy in both frontal temporal areas but very little loss in other brain areas.
However, I was rather surprised to see the consultant and his registrars referring to medical journals at Peter's first assesment review meeting. They all turned to each other and said things like "well, I think it's like page 75, what do you think?" There was lots of toing and froing of ideas until they all settled on "most probably Picks, but definately some sort of FTD"
And I thought they were the experts and I was terrified going into the meeting!
