Background: Somatoparaphrenia (SP) is a neuropsychological condition, mainly observed in brain-damaged patients, characterized by the delusional belief about the patient's body, that the contralesional limbs belong to someone else. The key feature of SP is, therefore, the presence of an ownership misattribution of the denied limbs. The present scoping review aims to give a proper definition and specific diagnostic criteria for SP, which, due to its nature, has been subjected to many misdiagnoses throughout history and in literature. Moreover, the deficits connected to the disorder are identified in the review, and a discussion on a theoretical categorization of SP is opened. Methods: The studies in the scoping review were selected by searching keywords in the PubMed portal. The studies included in the review had to be case studies, case reports, or review articles. To meet the inclusion criteria, at least one patient/case study, a disorder label/diagnosis, and a description of the patient's symptoms/ direct transcript of the patient disturb description were needed. Results: The review included 40 articles, 23 of which contained misdiagnoses. The patient sample consisted of 153 individuals: 42 were correctly diagnosed with SP, 55 were misdiagnosed, and the remaining 56 were diagnosed with other disorders of bodily awareness. The most common misdiagnosis was Delusional misidentification, and the most common deficit was extrapersonal neglect. Conclusions: The present scoping review contains a new and more unified view of SP. It offers more detailed criteria for a precise diagnosis of SP, defining the main characteristics unique to this disorder. Identifying the deficits connected to SP is relevant to understanding the severity of the illness. Finally, the reasoning behind the idea of the disorders of bodily awareness being placed on a continuum, and among these disorders, if SP itself can belong to said continuum, could have great diagnostic significance.

Abstract
Background: Somatoparaphrenia (SP) is a neuropsychological condition, mainly observed in brain-damaged patients, characterized by the delusional belief about the patient's body, that the contralesional limbs belong to someone else. The key feature of SP is, therefore, the presence of an ownership misattribution of the denied limbs. The present scoping review aims to give a proper definition and specific diagnostic criteria for SP, which, due to its nature, has been subjected to many misdiagnoses throughout history and in literature. Moreover, the deficits connected to the disorder are identified in the review, and a discussion on a theoretical categorization of SP is opened. Methods: The studies in the scoping review were selected by searching keywords in the PubMed portal. The studies included in the review had to be case studies, case reports, or review articles. To meet the inclusion criteria, at least one patient/case study, a disorder label/diagnosis, and a description of the patient's symptoms/ direct transcript of the patient disturb description were needed. Results: The review included 40 articles, 23 of which contained misdiagnoses. The patient sample consisted of 153 individuals: 42 were correctly diagnosed with SP, 55 were misdiagnosed, and the remaining 56 were diagnosed with other disorders of bodily awareness. The most common misdiagnosis was Delusional misidentification, and the most common deficit was extrapersonal neglect. Conclusions: The present scoping review contains a new and more unified view of SP. It offers more detailed criteria for a precise diagnosis of SP, defining the main characteristics unique to this disorder. Identifying the deficits connected to SP is relevant to understanding the severity of the illness. Finally, the reasoning behind the idea of the disorders of bodily awareness being placed on a continuum, and among these disorders, if SP itself can belong to said continuum, could have great diagnostic significance.| File | Dimensione | Formato | |
