Delusion in DSM-5: A Response to Lisa


Kengo Miyazono
This post is a response to Lisa's earlier post on delusion in DSM-5.

Is the definition of delusion really different between DSM-5 and DSM-IV?

In DSM-5, definitional remarks on delusion appear twice; first, in "Schizophrenia Spectrum and Other Psychotic Disorders" in Section II (p.87) and, second, in "Glossary of Technical Terms" in Appendix (p.819). So, we need to look at both of them and compare them to their counterparts in DSM-IV.

Reactions to the Question: Are Delusions Beliefs?

Sam Wilkinson
I am currently a Postdoctoral Research Fellow at Durham University, as part of a Wellcome Trust funded project that examines voice hearing (hearingthevoice.org). Recently, I completed my PhD at the University of Edinburgh on monothematic delusions caused by brain damage.

The issue of whether delusions are beliefs has been central to philosophical work on delusion, as several of the previous posts here reflect (see especially Bortolotti and Gerrans). I'd like to express a few reactions to this debate.

Obviously, before we can ask whether delusions are beliefs, we need to get clear about the nature of delusions, and the nature of beliefs.
