Abstract
This case study explores the psychological and neuropsychological traits of a 55-year-old woman, D.R., who has Cotard's, believing her torso has dissolved and food bypasses her legs. Her delusion emerged amid major depressive disorder with psychotic features, following prodromal symptoms like body distortion and somatosensory abnormalities. A neuropsychological assessment during remission revealed low-level visual perceptual deficits in an otherwise intact cognitive profile. Subtle distortions in bodily signals and specific attribution styles were identified as vulnerability factors, suggesting that the delusion may emerge when already strained information processing systems are further challenged. This relates to models of delusion formation.
期刊介绍：
Neurocase is a rapid response journal of case studies and innovative group studies in neuropsychology, neuropsychiatry and behavioral neurology that speak to the neural basis of cognition. Four types of manuscript are considered for publication: single case investigations that bear directly on issues of relevance to theoretical issues or brain-behavior relationships; group studies of subjects with brain dysfunction that address issues relevant to the understanding of human cognition; reviews of important topics in the domains of neuropsychology, neuropsychiatry and behavioral neurology; and brief reports (up to 2500 words) that replicate previous reports dealing with issues of considerable significance. Of particular interest are investigations that include precise anatomical localization of lesions or neural activity via imaging or other techniques, as well as studies of patients with neurodegenerative diseases, since these diseases are becoming more common as our population ages. Topic reviews are included in most issues.
