A high variety of factors have been implicated in the emergence of depersonalisation and derealisation episodes, including different drugs. A case abruptly induced by two applications of reboxetine, a selective and specific norepinephrine reuptake inhibitor, is reported occurring in a 50-year-old woman treated for a major depressive episode. The episode rapidly remitted after discontinuation of reboxetine. Previous data having indicated a role of the serotonin system in the pathophysiology of the phenomenon, a noradrenaline induced serotonin liberation of Raphe neurons is suggested as possible underlying mechanism.

A strong and specific link between obsessive-compulsive disorder or symptoms (OCD/S) and a tendency for dissociative experiences (e.g., depersonalization-derealization, absorption and imaginative involvement) cannot be explained by trauma and is poorly understood.

The clinical heterogeneity of dissociation constitutes a challenge to the culture-sensitive clinician. Variability in experiencing dissociation, the interplay between acute and chronic conditions, and the predominance of a nosologically interface-type of clinical surface conceal core dissociative symptoms. While the latter (amnesia, depersonalization, derealization, identity confusion, and identity alteration) usually remain underreported, the clinical surface may be dominated by acute (functional neurological symptoms, brief psychosis, an experience of possession, or acute dissociative reaction to a stressful event) or chronic (mood and personality disorders) secondary syndromes.
