Dissociative identity state-dependent working memory in dissociative identity disorder: a controlled functional magnetic resonance imaging study.

ABSTRACT:

Background

Memory function is at the core of the psychopathology of dissociative identity disorder (DID), but little is known about its psychobiological correlates.

Aims

This study aims to investigate whether memory function in DID differs between dissociative identity states.

Method

Behavioural data and neural activation patterns were assessed in 92 sessions during an n-back working memory task. Participants were people with genuine diagnosed DID (n = 14), DID-simulating controls (n = 16) and a paired control group (post-traumatic stress disorder (n = 16), healthy controls (n = 16)). Both DID groups participated as authentic or simulated neutral and trauma-related identity states. Reaction times and errors of omission were analysed with repeated measures ANOVA. Worki
