The aim of the article is to describe the revised consensus criteria for the clinical diagnosis of dementia with Lewy bodies (DLB) in 2017. The criteria for the clinical diagnosis of DLB were first published as the first consensus report in 1996, and were revised in the third consensus report in 2005. After discussion in the International DLB Conference in 2015, the International DLB Consortium published the fourth consensus report including the revised consensus criteria in 2017. The 2017 revised criteria distinguish clearly between clinical features and diagnostic biomarkers and give guidance about optimal methods to establish and interpret these. Diagnostic weighting of REM sleep behaviour disorder (RBD) and iodine–123–metaiodobenzylguanidine (MIBG) myocardial scintigraphy was increased. Future directions include development of the criteria for early diagnosis (prodromal and preclinical DLB) and pathological evaluation of diagnostic accuracy of the 2017 revised diagnostic criteria.
