Adaptive immersive Virtual Environments as a treatment for depersonalization disorder

Psychiatriki. 2021 Aug 5. doi: 10.22365/jpsych.2021.032. Online ahead of print.ABSTRACTDepersonalization is a dissociative disorder associated to a profound disruption of self-awareness in the form of emotional numbing and feelings of disembodiment. The salient feature of depersonalization is a breakdown in the familiarity of one's psychological and somatic self (and surroundings when derealization is also present), in spite of being aware of the unreality of the change. At an early stage of research it was realized that people inclined to dissociation find it harder to tolerate discontinuity in perceptual environments, possibly due to a rigid perceptual attitude. Consequently, perceptual discontinuity experienced during momentary immersion into a VE would be expected to increase symptoms of dissociation among individuals prone to develop them. It has been put forward that a tendency toward immersion or absorption, linking to imaginative processes underlying the dissociative experience, significantly relates to the level of change in virtual reality-induced dissociative symptoms. Consequently, it has been implied that increased tolerability of perceptual discontinuities and a more flexible perceptual attitude in people suffering depersonalization/derealization disorder may be of help. We propose the use of adaptive immersive virtual environments to the treatment of depersonalization. In particular, we propose that implementation of biofeedback electrical stimulation to detect...
