TL;DR: There is consistent meta-analytical evidence for better long-term prognosis of brief psychotic episodes compared with remitted first-episode schizophrenia and there was no prognostic difference in risk of psychotic recurrence between ATPD, BPD, BLIPS, and BIPS at any follow-up.
Journal ArticleDOI
Lack of Use in the Literature From the Last 20 Years Supports Dropping Traditional Schizophrenia Subtypes From DSM-5 and ICD-11
TL;DR: Factors strongly support DSM-5 and ICD-11 proposed elimination of traditional schizophrenia subtypes from a research and evolving knowledge perspective because traditional subtypes are simply no longer being used much in the scientific literature.

Elliot C. Brown,Samantha M. Hack,James M. Gold,William T. Carpenter,William T. Carpenter,Bernard A. Fischer,Bernard A. Fischer,Kristen P. Prentice,James A. Waltz +8 more
TL;DR: It is argued that performance deficits on the Iowa Gambling Task in SZ patients are more likely the result of a reinforcement learning deficit, specifically involving the integration of frequencies and magnitudes of rewards and punishments in the trial-by-trial estimation of expected value.
