Always wanting to call someone by a different name, or actually doing it, because they look like or remind you of that other person. A disorder closely related to "namesia."
My clonesia kicked in as I saw "Al" walking toward me -- no, that's "Charlie" (I think). So, I kept my greeting to a simple, "Hi, how are ya?"

Inability or slowness to recall peoples' names. Especially in the case of names that you should be able to remember because you see the person more than occasionally. A variation of namesia is always wanting to call someone by a different name because they remind you of someone else (see "clonesia").
At the family reunion, I was embarrassed that my namesia prevented me from recalling my cousin's name.
