There often does not seem to be any rhyme or reason to which people are “remembered” and which are not by a person with Alzheimer's disease (AD). Generally, those individuals who have been known by the person with AD the longest, or those who lately are in most frequent contact with the person, tend to be remembered better, though this certainly is not always the case. For instance, an AD patient might not recognize his own wife but instead remember the boss he worked for 30 years prior.
