Capgras syndrome: a reduplicative phenomenon.

A patient recovering from a severe head injury developed a prolonged Capgras syndrome in which he believed his wife and five children had been replaced by nearly identical substitutes. Although this phenomenon is considered a functional disorder in the psychiatric literature, recent reports postulate an organic basis. Recent studies of the comparable neurologic disorder, reduplicative paramnesia, have stressed the importance of bilateral frontal and right hemisphere pathology. Neuropsychologic and neuroradiologic data in our patient revealed this combination, suggesting that the Capgras syndrome may be a form of reduplicative paramnesia with the same pathologic substrate.

An extraordinary form of confabulation.

We describe five patients with spontaneous, persistent confabulation. While the basis of confabulation in general is not known, the evidence in this specific group of patients with spectacular, impulsive, and spontaneous confabulation suggests a marked deficit in frontal function, superimposed upon a basic defect in memory, as a possible mechanism.

Assessment of neuropsychological dysfunction in frontal lobe degeneration.

The quality of the neuropsychological investigation of behavioural changes in frontal dementias is dependent on the specificity of the behavioural analyses. A review of methodological issues and published findings identifies possible potential reasons for misinterpretation of research neuropsychological data in these studies. The areas reviewed include the operational definitions of terms such as 'frontal lobes' and 'frontal functions'; identification of experimental limitations in frontal lobe research; and highlights of neuropsychological investigations of frontal lobe functions. These deliberations suggest a practical approach to the behavioural assessment of frontal dementias.
