16 Sep 2021 webinar at 6 pm: The many faces of dissociation: Concepts and phenomenology of dissociation and dissociative disorders

16 Septembrie 2021

Trauma-related dissociation is not conceived as a unitary phenomenon. Its fragmentary nature leads to a multitude of phenomena despite their common ground, clearly demonstrated in dissociative identity disorder (DID), the most pervasive dissociative disorder. Furthermore, dissociation may accompany almost every psychiatric disorder, influencing their phenomenology as well as their response to treatment. If not accurately detected, dissociation can interfere with proper diagnostics and assessment, and presents a confounding factor in research. Therefore, we are delighted to invite clinicians and researchers to participate in this triadic webinar where two leading experts in the field of trauma and dissociation, Prof. Vedat Sar and Prof. Martin Dorahy, will present updated information on the main concepts and phenomenology of dissociation, including new knowledge on the nature of amnesia across identities in DID.

Thursday, September 16th 2021, at 6.00-9.00 p.m. (GMT+1, Brussels / Berlin / Warsaw / Madrid time)

More specifically, the agenda for the webinar is:

6.00-7.00 p.m.: "The many faces of dissociation", by Vedat Şar. This presentation will primarily focus on definitions, symptoms, symptom clusters, and clinical presentations of dissociation including the penomenological overlap with a series of general psychiatric conditions. Key informations about clinical and standardized assessment of dissociative disorders will also be provided. Therapeutic implications of each presentation type will also be addressed.

7.00-8.00 p.m.: "Memory problems across identities in DID", by Martin Dorahy. This presentation will primarily focus on inter-identity amnesia in DID. Following an outline of research findings, including those from recent empirical work, efforts will be made to account for these findings and what they tell us about DID. Memory, metamemory and self processes may be needed to offer a full account of inter-identity amnesia.

8.00-9.00 p.m.: Panel discussion
