Abstract
This case series elucidates pathological signs for diagnosis in two patients with Dementia. The first case highlights the term 'Smartphone sign', a novel psychopathology uncovered based on the existing 'TV sign', a rare type of delusional misidentification syndrome (DMS). The second case had symptoms consistent with the 'TV sign'. The possible underlying cause of these signs was hypothesized based on psychopathology, brain region, sensory system, cognition, and environmental factors. Moreover, the treatment outcome in terms of cognition and behavior on low doses of Risperidone and Escitalopram shows promising results and paves the way for the treatment of other DMS.
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.
