Depersonalization

August 13, 2009 Mauricio Sierra

Depersonalization, a dissociative disorder marked by altered self-perception and detachment from reality, is as common as schizophrenia or bipolar disorder yet often overlooked in psychiatry. This book reviews the condition from historical, conceptual, clinical, transcultural, pharmacological, and neurobiological angles. Recent neuroimaging studies offer new insights, opening opportunities for pharmacologic and psychotherapeutic symptom management. The work is relevant to psychiatrists, clinical psychologists, primary care practitioners, neurologists, and psychiatric nurses.

Unpacking the depersonalization syndrome: an exploratory factor analysis on the Cambridge Depersonalization Scale

Psychological Medicine October 1, 2005 Mauricio Sierra, Dawn Baker, Nicholas Medford et al.

Depersonalization symptoms cluster into four distinct but related domains rather than forming a single syndrome. An analysis of responses to the Cambridge Depersonalization Scale from 138 patients diagnosed with depersonalization disorder identified four factors that together account for 73.3% of the variance: anomalous body experience, emotional numbing, anomalous subjective recall, and alienation from surroundings. This suggests that depersonalization is not a unitary condition but comprises separable psychopathological dimensions.
