Abstract
Dementia with Lewy bodies (DLB) is strongly associated with Alzheimer disease (AD)-type pathology and tends to mask the core clinical features of DLB. Therefore, there may be cases of undiagnosed DLB without suggestive biomarkers of DLB. We describe the case of a 63-year-old woman who was initially diagnosed as having AD and later diagnosed with DLB based on suggestive biomarkers of DLB. In this case, transient sleep talking with physical movements for several days led to the assessment of suggestive biomarkers for DLB in the absence of the core clinical features of DLB. For clinicians, diagnosing DLB in patients with AD-type pathology is challenging. However, the application of biomarkers suggestive of DLB to all patients with dementia is not realistic. To overcome the difficulties of clinical diagnosis of DLB, further research is needed regarding strategies for the application of suggestive biomarkers for DLB to appropriately diagnose DLB.
期刊介绍：
Alzheimer Disease & Associated Disorders is a peer-reviewed, multidisciplinary journal directed to an audience of clinicians and researchers, with primary emphasis on Alzheimer disease and associated disorders. The journal publishes original articles emphasizing research in humans including epidemiologic studies, clinical trials and experimental studies, studies of diagnosis and biomarkers, as well as research on the health of persons with dementia and their caregivers. The scientific portion of the journal is augmented by reviews of the current literature, concepts, conjectures, and hypotheses in dementia, brief reports, and letters to the editor.
