I m 70 years old...in the past year or so I ve found myself not being able to think of a word...common words that I know perfectly well, but just cannot pull it up! Simple words like apricot or simple words in conversation...its just not there. But if I concentrate for several minutes it will almost always come to me. I m very concerned that it might be the onset of Alzheimer s. I ve always had a very good vocabulary (just now as I am writing this, I couldn t come up with the word vocabulary ....I had to think for a minute or so for it to come to me) and its very frustrating and worrisome... I don t have any of the other symptoms listed in early onset Alzheimer s....no losing things or putting things in strange places, I don t forget how to get to familiar places, etc. Does this seem a normal aging problem or could it be something more?
