It is about memory loss, how much is enough to be concerned and ask your doctor about it. It is the big alzhimers, is it is , or is it not. I have real trouble with short range, and one that scares me most, is I need to stop and think about my right and left. Another one I should remember is my address and phone number. I have trouble with words. Trying to get the right word and I can t find the right words to hold a normal conversation. It really scares me.
