Abstract	Delusional misidentification syndrome is more commonly associated dementia with Lewy bodies. We presented a case of probable DLB presenting with Cotard syndrome and a case of probable DLB presenting with nurturing syndrome. After Ramachardan's explanations for Capgras syndrome, we discussed the neurobasis of delusional misidentification syndrome, especially, Cotard syndrome and nurturing syndrome and hypothesized that delusional misidentification syndrome was attributable to the defective visual perception and the dysfunction of amygdala. These features, which are compatible with neuropsychological and neuroimaging findings in DLB, likely reflect the distributions of the pathological changes in DLB
Keywords	Dementia with Lewy bodies, delusional misidentification syndrome, Capgras syndrome, Cotard syndrome, nurturing syndrom
