Clinical features and diagnosis of dementia with Lewy bodies
WEBAug 22, 2024 · Dementia with Lewy bodies (DLB) is one of the most common types of degenerative dementia, second to Alzheimer disease (AD). In addition to dementia, distinctive clinical features include visual hallucinations, parkinsonism, cognitive fluctuations, dysautonomia, sleep disorders, and neuroleptic sensitivity. …

Neuroimaging characteristics of dementia with Lewy bodies
WEBApr 9, 2014 · Structural MRI has been widely used to compare regional structural changes in patients with DLB against AD, PDD and their healthy controls. In this section, we summarise the principal findings using MRI to distinguish DLB from other subtypes of dementia (Table 1).
WEBProbable DLB can be diagnosed if: a) two or more core clinical features of DLB are present, with or without the presence of indicative biomarkers, or. b) only one core clinical feature is present, but with one or more indicative biomarkers. Probable DLB should not be diagnosed on the basis of biomarkers alone. Possible DLB can be diagnosed if:

Differentiating Dementia with Lewy Bodies and Alzheimer's
WEBIn this study, we investigated how a deep learning approach would be able to differentiate DLB from AD with structural MRI data. Methods: Two-hundred and eight patients (101 DLB, 69 AD, and 38 controls) participated in this retrospective study.
Brain Imaging for Lewy Body Dementia
WEBThe first is a special MRI technique called functional MRI (fMRI). The fMRI takes advantage of the fact that brain cells increase their use of oxygen when activated giving off a special magnetic signal called BOLD (blood oxygen level dependent) activity.
