we have experienced many times in which we do not have facial recognition, and very few memories of one of my middle daughters. i have experienced this many times...when i awaken, or when i have been very drunk. I have no problem recognizing any of my other family members. It takes a few seconds to know whom she is. I am very worried about this. It is as if she does not have much of a presense. I am worried some day she will just dissapear from all of our memories.
