What Was The First Sign of Alzheimer's

 The first sign was my mother's inability to balance her checkbook.
But years before that, she decided that she could no longer drive- out of the blue this person who like to drive all over the place & shop suddenly said she couldn't keep up with it.  I just attributed it to poor hearing.
years later I can remember clothes shopping with her and she kept taking the shirt she had just chosen out of the cart and asking what it was over & over & over.
