Most psychological disorders show a steady rise in
prevalence from the mid-1980s through 2003. By contrast, the number of
publications regarding dissociative amnesia and DID rose from low levels in the
mid-1980s to a sharp peak in the 1990s followed by an equally sharp decline by
2003 (Pope et al., 2006). Worldwide, in 2003, the literature reported only 13
explicit cases of dissociative amnesia and DID. How would you explain this
phenomenon?
