After taking care of Bertie, I often wonder if my "antenna" is just
hypersensiive to any signs of alzheimers disease.  I know that Aunt
Flo seeing monkeys on the wall is a definite red flag.  We are getting
ready to do a family intervention and see how far we can get with that
before going on to the next step.

We are now having some real concerns about my 86 year old mother.  She
seems to have little if any awareness of any kind of social propriety.
What makes this so hard to accept is that it is so unlike her.  This
woman still gets up every morning and puts on full make up. Until
recently she would never dream of using the wrong fork, or eating with
her elbows on the table, or failing to send a thank you card, etc.  
Using improper English was something she absolutely looked down on.(
She has always been somewhat of a snob)  But my sister says that now
she sits around picking her nose, she passes gas in public, and she
cheats at scrabble.  You can't imagine what a change this is for her.
If I remember correctly, a fading social awareness was one of the
early signs with Bertie.  Is that typical?
