Cognitive Fragmentation Disorder (CFD) is a personality disorder caused by nanites. The nanites "overwrite" the victim's personality with that of an AI. Victims of CFD (or at least the AIs) refer to themselves as "monads"; while the more derogatory term, "headcase" has become popular in the shadow communities. Identified victims include several members of JackPoint; including FastJack, Riser, and Plan 9.
