Cognitive neuropsychological analysis of differential reading and spelling disorder mechanisms in a patient with aphasia.

abstract：:This paper reports the case of a patient, M.P., who developed delusion of inanimate doubles, without Capgras syndrome, after traumatic brain injury. His delusional symptoms were studied longitudinally and the cognitive impairments associated with delusion were investigated. Data suggest that M.P. did 'perceive' the ac...
