Capgras syndrome is a condition characterized by the belief that a relative has been replaced by an almost identical imposter. The disorder has been reported in several neurological diseases. We describe the uncommon case of a transient Capgras syndrome manifesting as focal temporal seizures in a woman with a right frontal meningioma. Our patient represents an exceptional case of Capgras syndrome for several reasons, namely, the association with meningioma, very rarely reported before, the transient manifestation of symptoms, and, most importantly, the epileptic etiology of reduplicative paramnesias. Lastly, our report also confirms the importance of frontal and right hemisphere dysfunction in generating Capgras syndrome-like delusions.

ObjectiveAsymmetry in brain structure and function is implicated in the pathogenesis of psychiatric disorders. Although right hemisphere abnormality has been documented in obsessive–compulsive disorder (OCD), cerebral asymmetry is rarely examined. Therefore, in this study, we examined anomalous cerebral asymmetry in OCD patients using the line bisection task.MethodsA total of 30 patients with OCD and 30 matched healthy controls were examined using a reliable and valid two-hand line bisection (LBS) task. The comparative profiles of LBS scores were analysed using analysis of covariance.ResultsPatients with OCD bisected significantly less number of lines to the left and had significant rightward deviation than controls, indicating right hemisphere dysfunction. The correlations observed in this study suggest that those with impaired laterality had more severe illness at baseline.ConclusionsThe findings of this study indicate abnormal cerebral lateralisation and right hemisphere dysfunction in OCD patients.
