Psychometric Investigation of Patients with Delusional Misidentification Syndromes
The term “syndrome of doubles” usually refers to the delusional negation of identity of familiar persons originally described by Capgras and Reboul — Lachaux (1923). This rare phenomenon has been explained on the basis of various pathogenetic frameworks summarized by Enoch et al (1967). Since the syndrome is characterized by a separation of the normally intergrated functions of perception and recognition, organic factors might be responsible for or might contribute to the pathogenesis of the syndrome. This possibility has been backed mainly by clinical observations (Gluckman, 1968; Weston and Whitlock, 1971; Nilsson and Perris, 1971; Mac Callum, 1973; Hay et al 1974; Hayman and Abrams, 1977) as well as by a study concerning 11 patients studied clinically and by EEG, echo-encephalographic, air-encephalographic and psychological methods (Christodoulou, 1977).
