title: [Dementia with Lewy bodies].
abstract: It is important to differentiate dementia with Lewy bodies (DLB) and other dementia, especially Alzheimer disease (AD), because the medical treatment, management, and the prognosis of these diseases are different. In regard to clinical features, DLB patients have relatively mild memory disturbance, fluctuating cognition, more severe disturbances of attention, executive function, visuospacial function, visual hallucination, depression, autonomic symptoms, REM sleep behavior disorder, and idiopathic parkinsonism compared to AD patients. In regard to imaging tools, DLB patients have milder atrophy of medial temporal lobe by brain MRI, reduced occipital activity by SPECT or PET, reduced MIBG uptake by MIBG cardiac scintigraphy, and low dopamine transporter activity in the basal ganglia by SPECT or PET.
