  • Title: Memory fragmentation in dissociative identity disorder.
    Author: van der Hart O, Bolt H, van der Kolk BA.
    Journal: J Trauma Dissociation; 2005; 6(1):55-70. PubMed ID: 16150685.
    Abstract:
    This study examined the quality of self-reported memories of traumatic experiences in participants with dissociative identity disorder (DID) and compared them with their memories of non-traumatic, but emotionally significant life experiences. Systematic interview data were gathered from 30 DID patients in The Netherlands. All participants reported a history of severe childhood abuse; 93.3% reported some period of amnesia for the index traumatic event, and 33.3% reported periods of amnesia for significant non-traumatic childhood experiences. All participants who had been amnestic for their trauma reported that their memories were initially retrieved in the form of somatosensory flashbacks. This suggests that, like PTSD patients, DID patients at least initially recall their trauma not as a narrative, but as somatosensory re-experiencing. Surprisingly, however, DID participants also recalled emotionally charged non-traumatic life events with significant somatosensory components, a phenomenon that has not been previously reported. This finding raises important issues regarding basic memory processing abnormalities in DID patients.
