Moments of memory loss are not uncommon, I think. Most of us will have gone upstairs and wondered why, or gone to the fridge for something, and forgotten what. It is the not knowing what the fridge is, that is when memory becomes a problem. A specialist told us that some time ago. When I was in hospital recently, I was asked to say the months of the year in reverse, I managed this easily, thank goodness, but there were one or two others who got so far and became confused, I think this is the time to start to worry,not Panic, but realise something is not quite right. (The reason I was asked to do this was because I had been asked how I slept, and I said badly, and when asked why, I said that I felt the bed was rushing away with me and it was quite frightening - the doctor put down against my reply "demented").
