Have We Not Progressed?

I came across this article, Differential Diagnosis of Dementia, from 1986.   In reading through it, it struck me that the diagnostic steps reads as if the article was written more recently.  In the 25 years since this article has written, it seems that we have not progressed much.  As we've found over the past several months, dementia, especially an early diagnosis such as Lyn's is still a differential diagnosis.
