Dementia with Lewy bodies (DLB) is the second to third most common cause of neurodegenerative dementia after Alzheimer’s disease (AD). It is characterised by cognitive fluctuations, visual hallucinations, and Parkinsonism. However at early stages, both diseases can present similar clinical phenotypes which obstruct differential diagnosis and proper treatment.In this study, we analysed resting state fMRI (rs-fMRI) images from AD and DLB patients as well as healthy controls using graph theory. The use of network analysis to the study of DLB revealed significant differences with AD and healthy controls
