Dementia with Lewy Bodies
Diffuse Lewy Body Disease; Cortical Lewy Body Disease; Senile Dementia of Lewy Type
Dementia with Lewy Bodies (DLB) is the second most common cause of dementia, accounting for approximately 20–30% of all cases of dementia (Zaccai et al., 2005). Patients may be present with dementia and later develop Parkinsonism or may develop Parkinsonism with dementia following. In those patients for whom Parkinsonism precedes dementia, an arbitrary cut-off for the onset of dementia of one year after the onset of Parkinsonism has been used to distinguish Dementia with Lewy Bodies B from Parkinson's disease with dementia.
