Progressive cognitive impairment is essential for the diagnosis of dementia with Lewy bodies (DLB). Deficits of attention function, executive function, and visuospatial function are characteristic of DLB, whereas memory function is relatively preserved. Cognitive fluctuations and complex visual hallucinations are core features of DLB, in which cognitive impairments are deeply involved. This chapter summarizes the way to detect the deficits in each cognitive domain and the features of the deficits in DLB, discussing the neural mechanisms of the deficits.
