Depersonalization is an unpleasant alteration in the perception or experience of the self, first comprehensively described by the French psychiatrist Ludovic Dugas in 1898 [1]. According to the American Psychiatric Association’s DSM-IV, “Depersonalization Disorder” is characterized by persistent or recurrent episodes of “a feeling of detachment or estrangement from one’s self” and “there may be the sensation of being an outside observer on one’s own mental processes”.
