Yes!
Juggling with words, and pronouncing them wrong or mix them up, to me is a sign that my symptoms are increasing.
One of the words I mix up without realizing is that I say "goodnight" to my daughter when I want to say "goodbye". She just looks at me with utter confusion, and then i realise i must have said it again.
Forgetting names, words, falling back to stupid descriptions of the word I cannot come up with.
"you know, the big yellow and blue thing, that brings you from one city to another"? "you know, the thing you can sit in and read a book while travelling?"
- You mean the train? ( Yes!)
Arggh!
