The author presents a review of 34 cases of Fregoli syndrome in the English and French language literature, discussing the syndrome's definition, aetiology and course and suggested that although an organic substrate may be found in some cases, it is the dominant psychotic theme which determines the content of the syndrome.
Delusional hyper‐identifications of the Frégoli type
Seven patients with the Frégoli syndrome were described. These patients were studied clinically and by routine laboratory tests, electroencephalograms (standard and sleep recordings, sphenoidal
Localization and lateralization in the delusion of substitution. Capgras symptom and its variants.
Five hundred and seventy cases in 252 reports of the delusion of substitution yielded 200 cases with an organic contributor to the occurrence of the delusion. In 79 cases lateralization or
The role of the right hemisphere in the Capgras delusion.
There was no difference in performance when the faces appeared bilaterally, which fails to support the hypothesis that poor interhemispheric communication may give rise to CD, and a model of what may be the right hemisphere mechanisms giving rise toCD was explored.

Psychodynamic approaches to the Capgras delusion: a critical historical review.
Over the last eight decades a plethora of psychodynamic explanations have been invoked to account for the Capgras delusion. While often ill-founded and convoluted, these formulations have, until
Psychodynamic approaches to the Capgras delusion: a critical historical review.
It is shown that psychosocial factors can and often do play a part in the development, content and course of the Capgras delusion in individual patients, but it remains to be proven that such factors are necessary and sufficient to account for delusional misidentification in general and the Cap Gras delusions in particular.
